Research On The Planning Of Urban Disaster-prevention And Avoidance Green Space

While we praise the city that have created unlimited wealth and civilization, frequent earthquakes, floods, terrorist attacks, other natural and man-made disasters have been bringing massive loss to the city in recent years, which also show us the vulnerable aspect of the city. China is a country which the natural disaster frequently outbreak .We still remember the tragic earthquake in 2008, drought of Yunnan and Sichuan, earthquake of magnitude 7.1 in Yushu of Qinghai, mudslide in Zhouqu of Gansu and so on, which have been shocking our heart again and again in this year .China is in the stage of rapid urbanization, urban population density is increasing. Meanwhile, china is a country which is short of land resources. Currently, in Chinese urban planning, how to arrange enough evacuation and disaster-prevention places in limited urban construction land is one of the major problems which must be focused on. Without doubt, constructing the evacuation and disaster-prevention place with green space is a effective way to solve the contradictory which between shortage of land for urban construction and land demand for disaster-prevention. Therefor, the research on urban disaster prevention and avoidance green space is imminent.Firstly, the writer analyzes the problems of urban disaster prevention and avoidance green space planning in china, and defines some related concepts. Then the third chapter has research on the personnel scattered behavior rule in emergency case and the planning indicators of disaster-prevention place home and abroad. Simultaneously unifies the related planning specification and constrcution situation of domestic park and green space. After this, the author proposes a set of planning specification of urban disaster prevention and avoidance green space which contains urgent disaster-avoidance green space, temporary disaster-avoidance green space, fixed disaster-avoidance green space, green evacuation routes and isolation buffer green belt, and suitable to chinese national condition. In the fourth chapter, the author constrcuts a network planning layout model of urban disaster prevention and avoidance green space with community, disaster-prevention district and city three levels, which based on thorough analysis of the problems existed in domestic urban disaster prevention and avoidance green space planning layout currently, also inspired by the ideas of The Security Community,Disaster-prevention District,Japanes Disaster -prevention and Living Area and so on, and the rationality of the model was verified in this chapter. .In the fifth chapter,the author summarizes and induces a perfect system of indicators for urban disaster prevention and avoidance green space matching facilities by studing on Haidian Park planning in Beijing ,Taipei City Disaster-prevention planning,etc., refering to the relevant urban planning standards, basic human common sense and so on, and considering the rules of personnel scattered behavior and the features of various types of avoidance green space.Next, the research results was used in the urban disaster prevention and avoidance green space planning of Luan city, the author believes that the feedback from the Luan practice would make the research more perfect. Finally, the author hopes that the research results would be the reference to urban disaster-prevention and avoidance green space in the future.
