| With global climate change have had a broad effect on human lives and production activities and urban construction and development, the research about global climate change causes more and more attention, how to respond to disasters which caused by global climate change has become a hot spot. Binhai New Area as a National Pilot Zone for Overall Reform, the developing speed of industry, population and economic is very quickly. Research on disasters risk assessment and prevention strategies, which disasters caused by global climate change in Binhai New Area, have great significance.The purpose of this paper is to study the responsibility of disaster prevention and reduction in Binhai New Area under the conditions of global climate change. Based on the investigation of the affection and mechanism between global climate change and disasters, collecting related data about natural disasters in Binhai New Area to establish a index system of disaster risk evaluation with the clear understanding of indicator standard. Use AHP method to determine the weight of the indicators and in an integrated way to score comprehensive disaster risk of Binhai New Area under the conditions of global climate change. Evaluation results show that the ability of comprehensive disaster prevention and mitigation of Tianjin Binhai New Area is greater, but still should be improved. Through analyzing the composite score of rule layer indicators results that we should raise emergency logistic support capability and put rational distribution of population and industry correctly to improve the comprehensive disaster prevention and mitigation in Binhai New Area. Based on the result of the disaster risk evaluation, use GIS platform to establish a geodatabase of Binhai New Area. On the support of the geodatabase, use the technology of spatial overlay analysis to get the vulnerability spatial distribution map of flood disaster, storm surge disaster, ground subsidence disaster and comprehensive disaster. Combined with the overall plan of Binhai New Area to give some suggestion to spatial distribution optimization.According to the results of comprehensive disaster risk evaluation and spatial analysis on vulnerability of disaster prevention under the global climate change, to give strategies of disaster prevention and mitigation from the management, policy and technology aspacts for Binhai New Area as theoretical support and layout proposals. |
