The Security Design Research About Exterior Space Of Architecture

In the traditional disaster-prevention research, we always focused on the strategy of architecture, comparatively, less about the security design of exterior space. As a matter of fact, multitudes will take refuge from leaving their inside space to getting exterior safe space. On the other hand, our urban disaster-prevention space system planning is separated in several mono-disaster prevention planning. As the improvement of urbanization, complication of urban functions, categories and characteristics are beyond our abilities.Therefore, we change the method of research, based on the exterior safe space, paying more attention to the succor, colligating the limited resource of the city. This article is mainly about efficiently and harmoniously planning and developing urban space from view of disaster-prevention. Some main points are as follows:First of all, considered from actuality, we found some conflicts between urban space developing and disaster-prevention. Put forward the concept of urban disaster-prevention space and point out space character and space form. This concept made up the limitation of traditional research and point out the main range of urban disaster-prevention space system involved in this article.Secondly, we study the strategy in detail on different levels. On the macro-level, the disaster-prevention ability of urban general space structure is focused from the view of city itself; On the middle-level, we discuss a basic unit of disaster-prevention and point out the main constitutes; On the micro-level, development of urban disaster-prevent facilities space system is also mentioned, mainly about factors design of facilities.In the last part of the article, we put forward some assumption and suggestion in the disaster-prevention space system of the exterior space in the city.
