Urban Disaster-prevention Green Space Planning And Construction In Multi-ethnic Areas

Security is a prerequisite for a livable urban. For the unexpected earthquake,the green space can play the enormous function. Disaster-prevention green space is the important part of urban spatial system of disaster prevention and also an indispensable type of urban emergency shelters. Multi-ethnic regions have many ethnic groups and there are different in costom and religion.The planning and construction of disaster-prevention green space is different from the non-ethnic areas. Study on the theory and practice based on the research gaps of the current disaster-prevention green space planning and construction in multi-ethnic area of China.The main content includes:(1)Summarizes and analyzes the development of urban disaster-prevention green space in domestic and foreign,according to the actual situation in China,explain the"disaster-prevention green space"and clearly the status of urban disaster-prevention green space system.(2)Disaster-prevention green space combined with urban green space system planning and urban planning on earthquake resistance and hazardous prevention. The role of disaster-prevention green space system is relevant to reasonable indexes. Considering the many factors to determine indexes of disaster prevention green system planning and disaster-prevention green space construction, to guide the construction.(3)Considering behavioral and psychological needs of disaster prevention, Proposed the theoretic of disaster prevention green space planning and construction and guided the planning and building. First, put forward the disaster-prevention green space service radius basis on population density and green capacity, and the urban disaster-prevention green space system spatial layout based on this theory.(4)Based on cultural diversity, different customs, socio-economic development of backward, discussed the construction methods of disaster-prevention green in multi-ethnic urban. Take Urumqi as the example, according to the ethnic composition, multicultural, population density, green space system characteristics and the spatial structure of urban development, build disaster-prevention green system, and the center for disaster prevention green space planning, to make recommendations the configuration of disaster facilities.(5)Disaster-prevention green space has multi-function.There are different contents and focus in daily management, disaster management and disaster recovery management.
