The discussion demonstrates the space design Abstract: Demonstrated that the spacialism design, will be refers to the specific goods decorates and the demonstration design according to the specific subject and the goal. It is take the information transmission as the goal space design form, including the museum, the science and technology museum, the Guangzhou Export Commodities Fair, the exposition and each kind sells, the exposition and so on, but also has the market inside and outside display windows and the booth, the shelf arrangement. The modern demonstration is one has the rich content, involves the wide realm and along with the time development, but enriches its connotation unceasingly the topic. Demonstrated that the environment the space design is also one by the environmental art design discipline primarily, involves other many kinds of related discipline the design domain. In the design method and the project approach, demonstrated that the environment design has the environmental art discipline related domain, like indoor aspect and so on design, public space design, landscape design and visual transmission design characteristics; Simultaneously has at the same time own specialized characteristic. Says from the demonstration angle, demonstrated that the spacialism design the goal is not the demonstration itself, but through the design, utilization methods and so on space plan, plane layout, light control, color disposition, builds a rich artistic power and the artistic individuality demonstration environment; And through this environment, has the plan, to have the goal, to gather logic the content development which demonstrated to give the audience, and makes every effort to cause the audience to accept the designer to plan the transmission the information. The demonstration design including the thing, the location, the person and the time four essential factors, these four essential factors in fact constituted “the space”. The demonstration designs the successful key to lie in the space design the success. Therefore, designs in the research demonstration, we creative the steric factor take key, from “space” the angle obtains, to carry on the modernized demonstration design the research and the exploration. The space is demonstrated that in the design the base element, this article from the demonstration design's spatial concept, demonstrated in the environment to function space's processing, demonstrated the space design some basic principles and so on have discussed the space problem initially which in the demonstration design involves. How to process in the demonstration environment spatial and the spatial relations, with using the demonstration in illumination, how the color and the decoration afforests to build the comfortable spatial atmosphere, demonstrated that spatial questions and so on function have done the careful research.
