国外sci论文有保发表的吗

sci源刊,级别较高。一般情况,单位是以检索为准,不是很好发

发表SCI论文不仅要求科研搞得好,而且必须还得有一个好的英语功底,在国内是最不容易发表的期刊。SCI论文本身来说,我国科研工作者大多面临英语能力匮乏的缺陷,尤其对于年龄大和专业性强的科技工作者来说,内容不是问题,英语往往成为了制约的瓶颈。SCI论文对我国大部分科技工作者来说依然是神秘的,难于发表的,正基于此,大部分科研机构、高校等单位引入作为评价标准,这也是有失公正,虽然缺少人为干预的评价标准,但科研工作者在工作的同时,不得不将精力浪费在于SCI论文的写作与发表;虽然使得我国科研可与国际接轨,培养我国科技工作者运用SCI官网进行现有论文和科技成果的查询与搜索的习惯,但制约了我国的科技水准,使科研人员不得不分出一部分精力用在外语上,使大量优秀研究成果流入英文期刊,破坏了中文期刊的发展,降低了中文在科技领域的“币值”。

肯定是不好发的呀,要不然就不叫sci了。我一直都认为,选择期刊的时候,不一定影响因子越高期刊就越好,你的文章不背录用也是白忙活,我建议还是在录用率高的期刊,如 汉 斯 出 版 社的

SCI是美国科学信息研究所出版的文献检索工具,是一种代表国际水平的检索数据库。被sci收录的期刊称为SCI期刊。要说怎么发表,就是写好你本专业的论文,然后你要知道并熟悉你那个专业的一些期刊,然后找一个适合你水平的期刊,投稿过去,然后等着消息就行了,通过了就等着发表,没有通过,继续修改继续再投稿。就是这么个流程。如果你着急发表,你可以去淘淘论文网看下,那边可以协助发表,但是主要是理工科的。如果文章质量比较高,建议你选择合适自己的期刊投稿试试。

国外发表的环保论文

生态经济 生态经济学是一个跨社会科学(经济学)跨学科的自然学科(生态学)。生态经济学是研究再生产过程中,经济系统和生态系统之间的物质循环,能量转换,和值的扩散规律及其应用的科学。生态环境已经从纯粹的自然意义上的人类生存的因子在社会意义上的经济因素,这有两层含义。首先,在与人类生活需要良好的生态环境已经出现供不应求的良好环境,已成为幸福的人们追求的目标之一。二,自然生态环境的废物吸收能力或接近饱和,在某些领域甚至已重载继续使用它的生产必须复制新的环境容量,因此需要投入资金,为“建设(生态恢复与污染控制)良好的生态环境,已成为“产品”的劳动。换句话说,良好的生态环境为目标,从生产的角度来看,具有双重功能,那就是,从生活的角度,已成为生产要素和条件。

What Environmental Disaster? We have developed a huge and thriving society; and in the process we deforest huge sections of land for living and livestock grazing. This decreases oxygen and increases carbon dioxide in the atmosphere; possibly adding to global warming though the greenhouse effect. This mass population produces mass amounts of waste, so to deal with that we just throw it into the ground, which in turn contaminates our water supply and contributes to further deforestation. We develop motorized transportation; and then burn non-renewable fossil fuels that put lead, carbon monoxide, sulfur and nitrogen oxides, ozone, excess carbon dioxide, and other harmful particulates into the atmosphere (Skjel & Whorton 95-108). This produces dangers like smog and cancer and contributes to global warming. In the production of fuel we exhaust oil reserves and pollute the oceans through spills from tankers. This endangers wilderness and wildlife. We produce an inert, easily producible propellant for aerosols; and then realize it's only inert on the ground. Once it's bombarded by UV ray in the upper atmosphere it releases a highly destructive ion that wreaks havoc on the protective ozone layer shielding us from those same deadly UV rays, creating a hole in the layer allowing the radiation through, increasing cancer and other genetic defects. We build rockets capable of going into space and breaking the earth's gravitational pull; and then immediately start to pollute this new environment with spent rockets and boosters along with other miscellaneous particles of debris (Curran and Haw 3). Michael Crichton writes, "What we call nature is a complex system of far greater subtlety than we are willing to accept. We make a simplified view of nature and then botch it all up. ...You have to understand what you don't understand. How many times must the point be made? How many times must we see the evidence? We build the Aswan Dam and claim it is going to revitalize the country. Instead, it destroys the fertile Nile Delta, produces parasitic infestation, and wrecks the Egyptian economy" (Jurassic Park 91). To the common person our current situation contains little hope. All the advancement and improvements have done little to further our species. With each one has come a new environmental issue. You almost need to evaluate each situation in terms of positives and negatives. However, at the root of all this chaos you'll find anthropocentrism, a human centered way of thinking. This way of thinking as an attitude, and moral theory, centers on humans as the highest of the significant beings. The theory views nature and the environment in terms of their use value for humans only (Michaels 7). So all of the above developments with costs can be justified through their usefulness for humans. The human centered ethic is deeply rooted in the past through the ancient Greek and Roman societies. To pursue further development based on this ethic would be disastrous. With our current numbers of population and rate of growth we're just asking for an environmental catastrophe of the highest magnitude to act as a wake up call. Granted that a great deal of the population realizes that unless action is taken today then we'll have to face that disaster tomorrow. The principle question is how to go about alleviating and repairing the damage we've already caused. We also need to address how to prevent doing further damage for the sake of future generations. The only problem with this view is that it is still a human centered ethic. It still sees the environment as a thing to be utilized by humans for their own pleasure. It doesn't do enough. The problems aren't getting fixed. Better ways of doing things are being researched, but the underlying problem is not receiving any attention. So the environmental downward spiral is only slowed down and is not fixed. We've still got the same problems. To take the conservationist attitude further you would see all sentient beings as holding moral standing and due consideration. This includes most of the animals in the world; any animal capable of experiencing pleasure and pain. Through these experiences you form the basis for the extended moral theory. If the animals perish through their habitat's destruction or outside influences, then their future pleasures will no longer be. When you take into account whole societies and communities of animals then the added value to the environment increases exponentially as you combine their happiness with the happiness never experienced by their future generations (Singer 275-276). So by taking this viewpoint you place even more intrinsic value on the environment through the experiences of all sentient animals involved. But at a time when our behavior may well lead us to extinction, I see no reason to assume that we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion" (The Lost World 7-8). Granted this does not present a case for sentience on the basis of pain vs. pleasure, but it does present an interesting way to think about classifying sentience. So you can see drawing the cut off line for even lower animals could present considerable challenges. You have trouble reaching an adequate definition of "sentient." You are now facing how much awareness a creature has to perceive pain and pleasure along with joy from anticipation of future events to consider it morally significant. If a cat is significant, but not a fish, what makes the cat a moral patient while the fish is not? Where is there a difference? There is a problem of arbitrarily assigning moral value when actual feelings and emotions are beyond description. To go a step further away from human sentience you would hold all living thing to be of moral value. This would then bring plants and non-sentient animals into the picture. This view holds life as the ultimate intrinsic value. Beings have moral value in just being alive. So life is viewed as an intrinsic good, and no verifying pleasures or pains being experienced are needed to allot this worth. Anything living is held with a reverence for that life (Singer 277-278). 2】The Environmental Revolution - We Can Make a Difference! Since the first time having blown bubbles in my Open Water class, I've logged over 100 dives. This love for diving has evolved into an intense passion towards protecting the ocean, and all of its inhabitants. I've chosen to put my love for the ocean into action, as an environmentalist. Actually, this passion extends out towards efforts that look to help all the planetary domains gain protection. As such, I appreciate when others take the time educate me on those other realms for which I know less about. To be an environmentalist, one must choose the cause which resonates within ones sole, and run with it. One must be willing to educate people about the environment while being open to education from those people who support other causes. Together we can help each other towards learning how to become a true "Environmentalist". We must all encourage positive collaboration and education as opposed to being against something. For example, sharks are being decimated to near extinction simply for their fins. The fins are used to make Shark Fin soup, a delicacy popular particularly in Taiwan and Singapore. It would be easy to blame these communities for creating the demand. However, in conversing with Asian environmentalists, they liken the culture around eating Shark Fin soup to the culture surrounding Americans eating turkey for Thanksgiving dinner. There are ongoing efforts to educate these people, by members of their own community, on just how dangerous this cultural practice is and the devastating impact this could have on their (our) world if all the sharks were to disappear as a result. Environmentalists everywhere are making a difference! Famous restaurants have taken endangered Swordfish off their menus, these same restaurants are buying wild-caught salmon (and boosting the economy of local fisheries in the process), laundromats have started selling green detergent, this just to name a few of these enlightened changes. This is how the "Environmentalist" can begin the revolution. Just find something you believe in and make a stand. One by one, we can make our planet a cleaner place to live, steeped in healthy bio-diversity for generations to come. 3Giving 1% to Protect Our Environment Though most of the world's surface is covered by water, since the Earth is so large relative to human horizons, there doesn't appear to be a shortage of land. However, when one begins to think of land in terms of a human resource, i.e., a producer of food, a provider of wood, an expanse for passage, one realizes that many portions are either too lacking in nutrients, too high in elevation, too prone to flooding, or too cold or ice-ridden for extensive use. Furthermore, habitable lands are becoming less abundant due to desertification (the expansion of deserts due to the misuse of land), agricultural expansions and rising sea levels. Since humans aren't the only species that need land, it isn't surprising that this resource is becoming limited for other forms of life too. In part as a result of this added stress on living things, we are also witnessing extinctions of grand proportions-at a rate of many thousands species per year. Since these losses are largely due to human actions, such as deforestation and non-native species introduction, many are beginning to pay attention to how we use and protect land. Recent ecological research has also recently provided a message of hope concerning the future well-being of life on this planet. In the world today, scientists estimate that the Earth is losing at least 1 percent of species every ten years, and the percentage loss may be close to 5 percent. Even if only the lower rate persists, the Earth will have lost near half of its biological diversity by 2070. Can this be possible? Many esteemed scientists think so. While the future appears bleak, several recent insights tell us that we have the potential to significantly reduce what amounts to a biotic holocaust, one not witnessed on Earth for over 60,000,000 years. While there are hopeful signs in the area of human activities (such as increased acreage of nature preserves and national parks), the hope of which I speak of here stems from specific characteristics of the other forms of life which may enable us to mutually coexist in the long term. The Earth's organisms are wonderfully varied in size, shape, function, behavior, and genetic code. One only need to consider that there are ~ 15,000 species of butterflies and ~50,000 species of mushrooms worldwide to begin to fathom the immensity of variety that this planet has. Yet, as different as the species come, the bulk of living things are also similar in a couple of very important ways. Most living things live in relatively small regions and do not travel far from where they or their parents were born. In fact, recent biological and ecological work has determined that most land species are very particular about where they live. As opposed to humans whose choice of home is largely driven by economic and political forces (mobility driven by availability of wealth or forced relocation), flora and fauna find themselves in locations for which they are adapted. We now know that many species of insects and plants have a very restricted range in which they found. Very few organisms are ubiquitous like we are. It goes without saying that you aren't going to find a Great Blue Heron or a Grizzly visiting Antarctica or climbing Mt. Everest; yet you might find the snow bear (recently discovered and previously known as the Abominable Snowman) doing the latter. Recognizing that most living things are rather localized during their lifetimes has profound implications, both hopeful and cautious. On the one hand, it suggests that we can learn a lot about species by parking our scientific minds in specific locations. On the other hand, it means that if we destroy even small areas of the globe we are likely causing great and even irreversible destruction to the species that are found there. We have also determined that there are specific locations on our planet where a disproportionate number of species live. For our species, Asia serves as the homeland for most. In fact more than 60 percent of humans lives on this largest of continents (which only makes up 24 percent of the land surface on the planet). With other life forms, geographic concentrations sometimes defy description. We only recently became aware that the vast majority of terrestrial (as distinguished from oceanic or riparian) species collectively live on just 1 percent of the Earth's land surface. (If humans lived at a comparable concentration level, we'd all have to cluster together in an area roughly the size of Antarctica or twice that of Australia.) This mind-blowing realization has prompted those that have been struggling to protect organisms a new way of thinking about such protection. They have concluded that if we humans could somehow find a way to avoid disturbing just 1-2 percent of the land surface, nearly 70 percent of the world's terrestrial species might be able to survive. Recently some conservationists have refocused their attention on these unique locations. The regions of the globe that contain such a splendid array of biological diversity have been named "hot spots," a name that communicates their critical status. In what has to be the most beautiful books I have seen, Hotspots represents the collective work of scientists Russ and Cristina Mittermeier and Norman Myers as well as photographer Patricio Robles Gil. In this oversized volume, these four scholars have assembled more than three hundred vivid photographs of some of the world's endangered species and threatened ecosystems. These absolutely breath-taking images come from the what they refer to as "the 25 most critically important regions" in the world. These regions originally constituted almost 12 percent of the world's land surface but now, due to human pressure at many levels, only a little more than 1 percent remains intact. What makes these locations, which are found on all continents except Antarctica, so "hot" is that they are home to hordes of the Earth's plants and animals and they face imminent danger from a variety of human activities. The Hotshot authors and others strongly believe that the global community can do wonders if these areas move to the top of our priority list. But what will have to happen for these spots to be protected? There are no simple answers to this central question. Unfortunately, those of us in the United States who have the luxury of time to even ponder such questions, face many obvious difficulties. First, nearly all of the hotspots are located outside of our territorial boundaries, exceptions being the forests of Oregon and California as well as portions of Southern Florida (namely the Keys and the Everglades). Key hotspots are found in New Zealand, Madagascar, and Indonesia as well as the continental parts of south-east Asia. Obviously we cannot expect that we will be able to force other countries to enact and enforce laws that will greatly reduce biological degradation. Yet, while many other countries have ratified the Biodiversity Treaty that was drafted at the 1992 Rio Earth Summit, it has never reached the floors of the U.S. Congress for a vote; Canada, Japan, and the European Union are among those to ratify it. By this inaction our nation apparently lacks the wherewithal to support global conservation efforts as a matter of principle. However, given that the wealthy nations in concert with international banks promote unsustainable extraction of resources in the world's developing countries, it would appear that we have an obligation to do so. If our national policy makers are unwilling to commit themselves to the protection of global ecosystems and species, we still have ourselves to look to for sources of positive change. All of us have tremendous purchasing power, especially in comparison to the majority of the other human residents on this planet; Barry Bearak, a Pulitzer Prize-winner journalist who recently spoke at Knox College's convocation, referred to the residents of the United States as "filthy rich," a conclusion he came to after spending a great deal of time in the poorer regions of the world, particularly Afghanistan and India. What we buy makes a difference. The environmental campaign to support shade coffee rather than sun coffee is just one of many attempts for the consumer to support sustainable practices in regions of great ecological diversity. According to the Northwest Shad Coffee Campaign, shade coffee agricultural allows for the extraction of a desired resource but at the same time allows between 3-8 times as many birds species to persist not to mention many more mid-size mammals as well as amphibians and beetles. Coffee is also a particularly important commodity in terms of the health of ecological systems because the countries that produce the bulk of it are precisely the same countries that are home to the majority of the world's species; the countries of Brazil, Bolivia, Indonesia, Vietnam collectively produce ~40 percent of the 17 billion pounds of coffee that are harvested each year (folks, that's more than 3 pounds per person!). Burdensome debts also force many developing countries to endlessly delay infrastructure investment. Debt-for-nature swaps, an idea proposed by Dr. Thomas Lovejoy of the World Wildlife Federation in the mid-1980s, have enabled poor countries to relieve foreign debt and international nongovernmental organizations (NGOs) to increase commitment to conservation programs both at the same time. In these swaps, NGOs pay off a poor country's debt to a bank or well-to-do country at greatly reduced costs in order to establish agreements for investment in national parks, for example. While not a cure-all, these efforts have begun the paradigm shift from unabated expansion and unhealthy extraction to one supportive of saving natural ecosystems and securing the health and welfare of all human populations. Threats to these locations represent massive scale intrusions taken by societies found on every continent. Unfortunately, there is so much that will be lost if these "special" places aren't quickly protected from future degradation. On the bright side though, so much of the world's genetic diversity lives in just a couple handfuls of "hotspots" that if these locations were saved hordes of species would be able to persist into the next millennium. The time is now to respond to this fairly recent observation and insight. It is time for the world to begin to act like a civilized 21st Century society. It is incumbent upon us, those with time and wealth, to maintain the momentum that others have started. The masses of life forms are relying on us to make the best attempt at this daunting yet critical task. Hopefully our species will be sensible enough to leave at least 1 percent of land alone, so that other life forms may continue to exist. Do we need all 100 percent? 写不下了,如果觉得不够,邮箱可否留一下,我继续补充

整个自然科学和社会科学的循环经济,是一个交叉学科,需要使用的知识,生态学,经济学,进一步划分也涉及哲学,植物和动物生态学,资源经济学,环境经济学,生态经济,工业生态等方面的内容,研究循环经济系统,往往采用物质流分析(分析资源的利用效率),生命周期分析,环境管理系统和其他工具。循环经济的发展理念,发展模式,产业形态,是一个系统的科学。 循环经济是人类经济活动的生态规律的科学的研究。循环经济是基于资源的使用效率和环境友好型的社会生产和再生产活动,新的生产方式的特点。所不同的是,传统的经济增长模式:传统的地球,从地球的一端无限的资源库和污水处理领域的经济增长,大量的矿产资源的消费电子产品在生产中排放大量的废水,废气和环境的废渣,另一端插入到“资源 - 产品 - 废弃物”的线性增长模式的体现。循环经济需要使用所有可用资源的生产和再生产周期的各个方面,提高资源的利用效率,物质代谢和/或共生关系,延伸产业链,被遗弃的 - “资源 - 产品 - 再生资源”的表现集约型增长模式的形式。循环经济是解决资源约束和环境污染的矛盾,这个想法的?发展是人类社会实现可持续发展的有效途径。 循环经济在最近几年中,不仅融入了中央决策在中国领域的,在前所未有的关注,也成为研究领域的重点。从“循环经济在中国长大,当地产业的实践经验的总结,循环经济发展规划的制定和实施,除了循环经济科学发展的理念,协调,可持续发展的体现,但也反映了发展循环经济的重要意义,为中国提高资源的利用效率,缓解压力,对环境的污染,实现社会经济的可持续发展。 :典型案例的卡伦堡模式 卡伦堡是一个沿海城市在丹麦,是世界上最成功的工业生态系统运行的模型。工业生态系统的植物群和动物群的生态系统中的共生原则适用于工业活动,形成了企业共存“产业链”。在卡伦堡生态工业园区,不同的企业从废物变成原料贸易有着密切的联系。卡伦堡生态工业园区,主要工业企业,电厂,炼油厂,制药厂和石膏板厂。四企业为核心,废物或产品在生产过程中,通过各种形式的贸易为其他公司使用的原材料,或取代部分的原料;本企业链的温室农场,养殖场,硫酸厂供热站,水泥工厂,农场。 循环经济的内涵及产生背景 周期“循环经济”的生态意义周期,而不是??经济学意义上的循环。生态循环,经济活动中的物质循环和新陈代谢,这是循环经济的讨论的重点主要涉及物质流循环在经济意义上,从时间的角度来看,体现在循环的区域互动的要求,从空间 循环经济是人类发展模式的反映,是一个不断发展的完善的过程。下的第一次工业革命之前,人类干预自然的能力,环境污染和生态破坏是唯一的局部的,小的,不起眼,它的影响是有限的。工业革命后,社会生产力的快速发展,人口迅速增长,人类社会活动的规模不断扩大,自然索取的能力,环境的干预也越来越大,资源消耗大,速度快,废弃物排放量显着增加,结合的局限性和主观睡眠的理解,从而导致更多和更严重的环境污染问题,污染事故频繁发生,对人类生命构成更大的威胁财产以及社会经济的发展,以在1962年,美国生物学家蕾切尔·卡逊出版的“寂静的春天”一书描述的大量使用农药对人类和环境的危害骇人听闻的案件,生动的语言,敲响了工业社会,的环境危机警报。1970年4月22日,美国举行了大规模的游行示威的保护地球环境,它标志着的人的高度关注有关全球环境问题的要求。在1972年,一个民间学术组织的科学家,经济学家和企业家 - 罗马俱乐部发表“的极限增长”的报告中,第一次正式发出警告世界:“如果世界人口,工业化,污染,粮食生产和资源消耗的趋势继续,的极限的增长在此星球有一天会出现在未来的一百年。 “这份报告被认为是第一个系统研究经济增长与人口,自然资源,生态环境之间的关系,科学和技术的进步。报告查看自然资源和环境容量的几分之一片面和悲观,但供应不符合点的外延生长,还提醒人们,生态环境作为经济增长的一个制约因素。从那时起引起世界的关注。同年,联合国发表了“人类环境宣言”, “郑重声明只有一个地球,人类开发和利用自然,但也承担了义务,保持自然的。 20世纪70年代,三大石油危机,让人们感受到在危机中的资源供给和提高资源的利用效率已成为人们的追求。在同一时间,在快速增长的固体废物管理战略,这是在海外发展循环经济和建立资源循环型首先,西方国家的社会中,大量的自然资源消耗在工业化的过程中,经历了长时间的产业化发展积累的大量的废物,如废钢铁,老旧汽车,废旧家电,废纸,废物循环再造的目标要求,以降低经济发展的成本。事实上,正是因为这些废物的基础上回收之前,只有发展循环经济的物质基础。 />近年来,中国的宣传,以促进世界经济周期的研究和发展。发布国内外一方面,大量的生态和经济方面的工业生态学专着或文章,但几乎没有循环经济专着;没有看到国外高等教育的学科设置的循环经济。另一方面,截至2004年底,中国不仅是循环经济的文章,专着或汇编出版也已发表论文近,循环经济是它的出版业在2005年的热门话题。可以说,循环经济是一个彻头彻尾的概念,中国学者根据自己的国情,创新发展理论和发展模式,同时,经济的情况下,全球化的日益推进,循环经济是国外学者已经提出了“中国因素”也不例外,在中国环境与发展国际合作委员会(国合会)由中国专家合作的外国专家参与深化循环的理论研究中国的循环经济概念的世界经济,外国专家,促进循环经济在中国的发展,吸引了国际组织和外国政府的关注,并成为与中国合作的重点领域之一。 涉及每一个公民,每一个家庭,每一个社区,每一个企业,每一个地区,乃至整个中国民族的主要经济周期的执行情况。例如,一个家庭的节能,节水,废物分类活动;一个办公建筑的能源的节约,前面和背面的复印纸,碳粉盒,水的使用,一个干净的生产企业,综合利用资源产业的发展,社会的废物分离和回收,利用太阳能再利用,这些活动可以产生降低系统物质流的影响,因而是圆形区域的经济。随着中国的工业化和城市化是不是还没有完成,它是可以实现材料减少经济活动,除非它会不再开发,这是违反我们的主张和推进循环经济的出发点,这是说,没有集中中国,以促进循环经济的发展。所谓的窄废物再利用循环经济,循环经济发展,相当于“垃圾经济”,“范围内的废物经济”,日本提出建设循环型社会,强调废物减量化,再利用和回收,与相应的静脉产业。周围形成所谓的“静脉产业废弃物资源化产业,与动脉产业动脉产业“指的是对自然资源的开发和利用,形成了行业。 研究基金会循环经济 讨论学科循环经济的基础,不能离开的综合性自然科学和社会科学。 1,生态基础 生态学研究生物和环境科学之间。作为仿生学循环经济是研究人的自然代谢,循环,共生和组织经济活动的法律为蓝本,英国学者坦斯利(AG坦斯利)1936年生态系统的概念,强调一定的自然生物和地理,生物和生物功能非生物环境统一的生态系统,包括生物和周围所有的空间和所有的生物直接或间接影响的有机体;影响经济增长,开发,复制,形态特征,生理功能和地理分布的环境条件,生态因素。法律生态系统可以归纳如下:整体,协调,循环,再生,生态规律已经被应用的领域,如农业,工业,循环经济的实践。 2,经济基础 > 从经济学的出生日期,资源分配,特别是分配稀缺资源的经济学的研究对象。渐渐稀少的生态环境条件,经济将扩大对生态环境的研究对象也就不足为奇了。 资源经济学,资源经济学认为经济的性质,将其转换为生存而数据的天然资源。资源的自然和社会资源,社会资源,包括人力,知识,信息,科学和技术,以及积累的资本和社会财富,其最大的特点是累积性和可变性。自然资源,包括土地,森林,草原,降水,河流和湖泊,能源,矿产资源,其本质特征是有限的,某些类型的不可再生的资源。循环经济研究与资源经济学包括的关系之间的供应和需求,价格和税收上的供给和需求的影响之间的关系。废物变成原始材料“链接之间的行业的能力,以形成和最终决定由资源经济学。 环境经济学。各国政府促进循环经济的发展,因为它涉及到的外部问题的原因。福利经济学告诉我们:如果一种商品的生产或消费会带来成本,也不能反映在市场价格将产生“外部效应”。外部是有害还是有益的影响不会直接参与这样的活动,企业或个人的一些产品的生产和消费。之一的有利影响,外部经济“,否则”外部不经济的“生态环境是一种公共产品。作为一个公共的环境中,”公地悲剧“ -

资源的可用性有着积极的作用,或直接在自然的能力,吸收压力。在后一种情况下,超过自然的废物直接排放到实用程序或资源的可用性产生负面影响的吸收能力。基于这个广泛的概念,包括的吸收能力,皮尔斯和自然资源管理的两个规则:可再生能源的可再生资源的开采速度不是它的速度,较小的排放到环境中的废物流比或等于的吸收能力环境。他们还提出了资源股的特点:可耗竭性资源减少(可持续发展)应该补偿的可再生资源的增加,达到一定的生活水准,我们必须减少消耗的资源或可再生资源股票(提高效率)。 类似的工业代谢,自然循环和工业循环的循环经济模式。这两个循环的繁殖,也就是提供的再生产和消费的物质基础;产生超过直接消费效用(如美的欣赏)的原料。自然循环被吸收的环境消化废物,废物吸收的经济来源承担的经济体制;工业循环有助于??减少自然同化能力的压力,而产生额外的资源。此外,循环也有助于减少对环境的同化能力的压力。但是,工业循环也需要资本投资,并产生额外的压力同化能力。也就是说,二次污染,导致吸收能力的下降。 循环经济的过程中,中国的发展 在中国发展循环经济有一个逐渐清晰的概念内涵,扩大重点进行调整,不仅为国家和性能环境法律,法规和标准,并制定了一系列的优惠政策,约束,鼓励企业开展资源节约和综合利用,推进工业“三废”,“吃干榨尽。可以推断,循环经济将成为实现可持续发展的方式之一。 在我们国家已经做了很多工作,以提高资源的利用效率 >自改革开放以来,国家制定了一系列促进企业的能源,水,土地,材料和资源节约法规,政策,标准和管理措施,加大结构调整和技术改造力度,以节约能源的主要内容,推广先进,适用的技术,流程和设备的发展,资源的利用效率已得到大大改善。统计显示,:在2003年,中国的能源消耗每万元国内生产总值在1980年下降65.5%;每万元GDP用水量相比1980年下降了84.7%;综合利用,工业“三废”的14.6倍,1985年的产值;报废回收的材料总价值的12.4倍,1985年,经济,社会的有机统一和环境效益。 首先,工业废物综合利用率。在重新冶炼渣屑制砖或烧制水泥,废钢回收利用的税收减免等政策激励,在中国的一些企业中,和重用冷却水和其他措施,开展企业资源再生或循环再造。2003年全国工业“三废”综合利用产值达40亿元人民币,工业固体废物综合利用率达到53%,综合利用率约65% ?粉煤灰,煤矸石综合利用率约56%。 返回。我们的的城市包装材料,如酒精和烟草包装纸箱回收废旧物资回收已经形成了相对供应的废物流零售商,批发商,批发商再集中返回的生产企业重复使用的,有些废料物质的分散回收集中分类,废金属加工成的冶炼厂,旧家具,废纸,塑料,废木材,废家电回收行业,已经形成了网络和规模,2003年,5000多名各类废旧物资回收企业,回收网点16万,超过3000个回收加工企业,从业人员140余人,再生资源回收利用的价值约50十亿人民币,在发展模式调整废料和社会回收网点遍布全国各地。再利用生产和消费的过程中,无论从事机械,电器等产品的生产领域的消费领域我们的维修团队,一些企业开展近年来开始探索和实践,一方面报废汽车发动机废旧机电产品再制造,实现资源的循环利用的包装材料,如玻璃容器,纸箱,周转箱的回收及循环再造。提高资源的利用效率,另一方面,解决供应配件停产的老款车型的产品更新,可谓一举多得。此外,国家鼓励发展的旧货市场,充分利用的跳蚤资源,以满足低收入消费群体的需求。 四,环保产业的快速发展。“末端”不属于循环经济领域的,但循环经济的内容。热利用城市生活垃圾分类,回收和最终处置生活垃圾堆肥处理和垃圾填埋气,废物转化为能源,形成产业链,循环经济的内容。2003 ,40多利用垃圾发电或热利用企业。加快沿海地区形成的中小型企业进入园区,污水集中处理模型的过程中,以市场为导向的工业废水和生活污水处理。 ,不仅是为了减少污水处理的资金,部分企业也成为当地的纳税大户。促进循环经济的努力,加强宣传国家的发展增加了近年。循环经济作为一个新的概念,有一个逐步认识和深化的过程。近年来,国家有关部门,新闻单位要加强对循环经济的概念,这个想法的?宣传,创造一个良好的社会氛围循环经济的发展,同时,绿色服务业(第三产业),环境标志认证体系,绿色学校,绿色社区,绿色政府采购是一些地方推进循环经济方向。 组织试点示范。中国的圆经济试点工作进行了三个层面上。大力推动清洁生产在企业层面,建立生态工业园工业园区,发展循环经济省,市试点,并取得了初步成效。 > 积极推行清洁生产。中国是国际上公认的清洁生产,取得了较好的发展中国家。在1993年,中国利用世界银行开展清洁生产试点项目,在酿造,造纸,化工等行业通过不断改进设计,使用清洁的能源和原料,采用先进的技术和设备,完善的管理和其他措施,以提高资源的利用效率,减少或避免污染物的产生。国家相关部门,重点对一些重大清洁生产技术开发和产业化示范工程,并在全国20多个省(自治区,直辖市),20多个行业,400多家企业开展清洁生产审核工作,建立了20个行业或地方的清洁生产中心,超过10000人参加了清洁生产的不同类型的培训,提高企业污染防治能力。 在集中地区促进生态产业发展。的行业,经济开发区,积极发展生态工业废物原料的上游和下游企业,延长生产链,从上游企业在这些公园生态原则的基础上,组织生产,实现高效区域或企业集团,废物的产生,甚至“零排放”的最低金额之间的资源分配,国家环保总局已批准了14种类型的生态工业园建设的公园在江苏省具有不同的功能,上海的废物饭盒回收产业链,天津开发区基本形成无废物排放园区。这些做法可以总结和推广。 取得了长足的进步,在发展生态农业。自20世纪90年代以来,该部农业部在两组51生态农业示范县,国家批准。经过积极探索农业领域,养殖业,农产品加工业总结出数百从材料的接触角,生态农业模式物质代谢类型的生态农业模式。 ,产业共生型和混合型三大类。 法律,法规和政策,创造体制环境 自改革开放以来,中国政府从法律,法规,政策,标准,发展循环经济的措施,以建立有利于资源节约和环境保护的制度环境约束和激励机制的引入。 首先,法律和法规不断完善。 2003年1月1日实施的“清洁生产促进法”第九条规定:“调整产业结构,发展循环经济,促进企业在资源和废物综合利用领域的合作,更有效地运用,回收资源“环境影响评价法”,“节约能源法”,“可再生能源法”,提出了发展循环经济的要求。 2004年修订的“固体废物污染防治和控制环境法:”国家固体废物污染环境的防治,实行减少固体废物和危险,充分合理利用固体废物和无害化处置固体废物的原则,促进清洁生产和循环经济发展。 “国家还推出了节能和长期规划。废旧家电及电子产品回收利用,清洁生产审计方法,轮廓节水技术”的规定进行了介绍。当地的法律和法规还介绍了2003年左右,陕西,辽宁,江苏等省份和城市,如沉阳,太原还制定了地方清洁生产政策和法规。贵阳市建设循环经济生态城市条例的颁布和实施。这些都依法奠定了基础,促进循环经济发展的。 通过优惠政策鼓励企业发展循环经济。资源综合利用,废旧物资,回收和环保产业,循环经济的重要组成部分,一直是国家鼓励和支持的工作。为了调动企业开展资源综合利用的积极性和主动性,国家发展和实施了一系列优惠政策,鼓励资源综合利用。例如,国家经贸委和国务院其他部门批准的1996年“意见”的进一步发展的资源综合利用(国发[1996] 36号),国家资源的综合利用经济和社会发展的长期战略方针。开发两批当前国家重点鼓励发展的产业,产品和技术目录“,根据国务院第36号,原国家经贸委,财政部,国家税务总局等部门联合下发的利废企业和产品的减免税优惠政策的有关优惠政策。 另外,国家有关部门组织了大量的理论和实践研究。在2004年中央财经领导小组办公室显著研究,“循环经济地位,中国的资源战略和措施,研究建立。由国家发展和改革委员会委托,国务院发展研究中心开展了循环经济政策,思考研究发展循环经济,建设节约型社会“十一五”规划。环境与发展国际合作委员会开展清洁生产和循环经济的专门研究。国家中期??和长期科学和技术发展规划战略研究,生态建设,环境保护和循环经济,科学和技术问题为主题。项目支持科学技术部,国家环保总局开展软科学的循环经济技术支撑体系。循环经济在中国的发展已引起国际社会的高度重视循环经济的优先领域的国际合作项目。例如,世界银行支持全国人大开展的研究循环经济的法律框架,以支持国家环保总局开展循环经济的政策研究,德国支持贵阳市循环经济的实践。所有这些都为中国循环经济的发展奠定了基础。

可以看下(环境保护前沿)这本期刊或者这类型的期刊~多看下论文~总能写出优秀的论文

sci期刊都是国外的吗

是的,上面说的对。

sci是美国《科学引文索引》

SCI全称Science Citation Index,翻译成中文的意思就是科学引文索引。SCI可以说是当今世界上最重要的几个检索性刊物之一。一般搞学术的人都知道,如果您可以发表一篇SCI,这对你的职业发展是多么的重要。

发表一篇SCI意味着保研几率大增。如果你非常优秀,可以在大学期间,发表1篇SCI论文,这对你保送研究生帮助非常大,分区越高,加分越多。但是,发表SCI并不意味着你一定可以成功,同时也要看你的学分绩点、专业课的成绩单、在班级和学院的排名等。

本科发表SCI对保研的好处还需要看具体的院校情况,每个学校保研都是有名额的,但是在同等条件下,发表SCI的本科生,容易优先获得保研名额;另一方面,保研的学生,往往还要进行面试,有含金量高的SCI,获得的认可度也比较高,通过面试非常容易。

总之,本科发表SCI对保研有好处,同时也要注意保研的其他要求。另外,发表SCI对本科生来说是一个很好的机会,而且SCI期刊的水准越高,对本科生的好处也会越多。

sci4大区:

中文被SCI检录也算SCI

SCI论文,是指被SCI,即科学引文索引所收录的SCI期刊上刊登的学术期刊论文。

我国民众对SCI论文概念模糊,小部分民众误认为SCI是一本期刊,此期刊由南京大学引入并成为各大高校和科研机构学术评价和奖惩的一类刊物。

SCI对全球的自然科学刊物进行考察,凡影响因子大于某一临界值的刊物,则可以进入SCI系统。 进入SCI系统的刊物分为两类,即内圈和外圈,前者的影响因子高于后者,前者称为SCI刊物,后者称为SCIsearch刊物。

扩展资料:

SCI由外国机构创办,是国内外学术交流的平台之一。但随着SCI论文相关标准“独霸”教育、科研领域各类重要核心评价体系,“科技创新价值追求扭曲、学风浮夸浮躁和急功近利”等弊端日益凸显。

“SCI论文至上”扭曲岗位评价导向。广东某高校人事处负责人说,当前教职工的科研项目、个人发展、薪酬待遇等都与SCI论文指标挂钩,这导致指标与岗位标准错位,导致管理、教辅等非科研岗位职工也盲目追求发表SCI论文。
