摘要
灾害损失的严重程度由致灾环境的危险性、承灾体的脆弱性,以及区域的应急能力决定的。承灾体脆弱性研究对灾害风险管理、区域防灾减灾、减灾投资,以及灾害保险等有着重要的意义。建立了针对自然灾害的区域承灾体脆弱性评估指标体系;在此基础上,引入精细化土地类型,基于GIS对承灾体脆弱性做了基于精细网格的量化模型研究;并以浙江德清县自然灾害区划为例进行了试验。
The seriousness of disaster losses is decided by the risk degree of disaster environment,vulnerability degree of disaster body and emergency response capacity of the region.The study on vulnerability of disaster body is of importance to disaster risk management,regional hazard prevention and investment in disaster reduction and insurance.An indexes system for regional vulnerability assessment of natural disasters is established.Refined land type data are introduced and a quantitative study on regional vulnerability by defining fine spatial grid as the basic evaluation unit based on GIS is conducted.As an example,the natural disaster zoning in Deqing country of Zhejiang province is tested.
