Southwest Mountain Urban Disaster Prevention Hedge Green Space Overall Planning Method Research

China is a mountainous country, mountainous city disaster grim. With the mountainous city scale southwest rapid expansion and population density of excessive concentration, sound urban disaster prevention system has become the urgent task. As urban disaster prevention system of urban green space is an important part of ecology, landscape, not only has the recreation and culture functions, but also with disaster prevention hedge function.Based on the Japanese and the European and American countries of rich experience, mountainous city from southwest, we analyzed the features of urban planning, the landscape, disasters elements of urban disaster prevention aspects, the influence of hedge green space based on the integration of southwest formed mountainous city characteristics of overall planning method disaster prevention hedge green hill, the construction measures southwest urban disaster prevention with green space system hedge construction standards, in order to enhance mountain urban disaster prevention hedge green maneuverability. The science of disaster and active hedge, used limited combining prevention based resources will maximize the function of green space.According to shelter the resettlement of behavior characters and green requirements, the paper puts forward the general planning of disaster prevention hedge green space planning methods including planning and implementation of the management two big system. Planning discusses in such planning mountainous city the characteristics and countermeasures, based on the characteristics of mountainous southwest, combined with more plagues mountainous city complex topographical layout structure, constructed urban disaster prevention system, define the suitable hedge green hill, green urban road network planning, and evacuation passageway for complex terrain site characters of urban disaster prevention hedge greenbelts construction standards; Implementing the management of the main management and operation system, from green hand, through the capital, regulation law and public participation to guarantee security prevention hedge green space system is established.In the end, the essay panzhihua urban disaster prevention hedge green space planning for empirical research. Based on regional environmental mr.zhang and urban development analysis, evaluation of urban development impact mostly hazards species; Based on current green space and urban planning the green land resources total size and space distribution of analysis, phases and points of regional make feasible construction standards. Integration of urban population distribution, urban functional partition and administrative boundaries, HuaShe comprehensive disaster prevention partition. According to each major disasters disaster partition type, clear within the type and division green green Spaces construction content. Integration of resources to optimize the disaster-reduction hedge green space, overall layout in satisfying the green capacity and service radius premise, according to the disaster prevention hedge green hierarchies determine its corresponding responsibility divisions. Relying on green city road, evacuation passageway organization, and according to the disaster prevention division level set corresponding disaster prevention with support system project.
