Mountain Ous City Shelter Accessibility Research

In recent years, with the earthquake, the earthquake in Haiti, Chile earthquake and Yushu earthquakes have occurred, the world's natural disasters are increasingly frequent trend. In China, Wenchuan, and Yushu of disasters on urban disaster prevention and disaster prevention in the community's attention to reach a new level, at the same time, China's rapid urbanization is storing up risks for urban safety, building evacuation lagging and safety education is still in the blank have increased the uncertainty after the disaster, especially when people leave the building, how to quickly and safely to shelter the evacuation of this important process has not conducted any relevant research and design making system for disaster prevention is not perfect.As a multi-mountain country, mountain area and the mountain city distribution and quantity of an important proportion of the city's construction and development of mountain has its own specific characteristics and the regularity of the structure because of terrain and urban roads in particular, post-disaster evacuation route the problem more complex study of this issue, in the city's comprehensive disaster prevention and disaster reduction and relief system, a very important position.In this paper, in drawing up the landscape of learning theory research methods, based on architecture and urban planning with subject knowledge, to study the theory of urban disaster prevention, urban green space system planning theory, combined with transport, urban safety theory, the environment factors theory theory and related disciplines based on the mountain city shelter accessibility study. First of all, up to the notion of system and its application, proposed the theory applied to shelter up to the strategy of shelter in the accessibility of content and features based on the accessibility system that reachability includes thinking up, visual and behavioral knock up. Then on the basis of theoretical research in Beijing, Shanghai, Chongqing and other cities of Panzhihua field shelters to take photos, people visit, and Design Institute interviews conducted research, and statistical analysis of the data to be summarized, that exist in the design with such unreasonable design, lack of security, lack of awareness on asylum issues residents. On this basis, combined with relevant cases and theories on how to improve shelter accessibility vision and ideas proposed optimization strategy. Again the spatial accessibility of shelters conducted in-depth analysis, the core factor in the proposed "security", and "efficiency" based on the point of starting from the designers to find their "road" "road network" " Construction "and" environment "aspect of the design factors, identify them with" security "and" efficiency "of the inner link, the method by a mathematical model to quantify the accessibility of space, design and research for the following reference.Object of this paper is the mountain city, in the course of study focused on the characteristics of a specific combination of its research focuses on accessibility, in particular the "safety factor" in mountain city in the particularity and importance of disaster prevention, through mathematical model of the way, the efficiency of accessibility and security issues, combined with the use of practical examples, draw reasonable conclusions for the design of shelters to provide new direction for urban disaster prevention and mitigation planning, management, decision-making reference to based.
