Research On The Water Network Of Urban Disaster Prevention And Mitigation Planning Strategies

The effects of natural disasters to human gradually become the focus of attention. In order to effectively deal with all kinds of natural disasters, establish a strong disaster prevention space system, improve the urban disaster prevention ability, to explore the relatively safe mode of the urban environment has gradually become the common concern of humankind today’s topic. The water network clouds, population and wealth accumulation along the water net area is located in one of the three natural disasters in China, All the year round by typhoon, flood and other disasters, serious disaster system complexity and loss is particularly prominent, proposed the urgent demand to the disaster prevention and reduction system and the scientific construction of urban.First of all, in the city of domestic and international disaster prevention and mitigation of theoretical research and practice of the comprehensive review and summary based on disaster prevention and mitigation research, summed up the development trend, combined with the water town environment characteristics and the main types of natural disaster prone, find out the problems in disaster prevention, analyze urban water network build disaster prevention and mitigation system faces major challenges. Secondly, combining urban water network typhoons, floods, fires and other disasters destructive characteristics and urban water network (disaster bodies) the vulnerability of features, key and space requirements analysis of major hazard reduction, and emphasizes the disaster derivation rules (longitudinal) research and disaster chain control core, the main spatial interoperability of disaster prevention and reduction of the (horizontal), and provide a theoretical basis for disaster prevention and mitigation measures in the implementation of urban space. Again, using the "figure-ground relationship" principle, the disaster prevention and mitigation measures to the construction of the urban space system of multidimensional perspective, in order to realize the active and comprehensive disaster prevention and mitigation. Finally, with the model of human behavior, urban construction, the comprehensive benefits of water environment, the principle of combining is proposed based on disaster prevention, construction of water town needs to focus on rivers, rivers, urban layout form of disaster prevention and disaster prevention space road system, the multistage network oriented, strengthen the different levels of disaster prevention mitigation planning on the cohesion, the space system of comprehensive disaster prevention planning strategy for water towns, and make the system at the same time have the maneuverability, to enhance the urban integrated disaster disaster recovery capability, to water towns are relatively safe and healthy sustainable development target method.This paper puts forward three new ideas on urban disaster prevention and mitigation research:First, focusing on water reticulation system space, combine the system of disaster prevention and reduction system and water town environment closely, crossing point for both and the balance point, strong coordination, construction of disaster prevention and mitigation system for water town; Second, grasp the core, active control, puts forward the core of disaster prevention and mitigation system should be in-depth analysis of derivative and role of disaster, spatial Interoperability for disaster prevention and mitigation, develop urban spatial system of disaster prevention initiative, spread to contain the disaster chain.
