浙江省雷电灾害易损性分析及风险区划

根据 2007-2011 年浙江省雷电灾害事故调查资料、浙江省地闪监测资料，选取地闪密度、灾害频数、经济（GDP）损失模数、生命易损模数、雷灾经济损失、人员伤亡等作为浙江省各市雷电灾害易损性评估指标，对浙江省各市进行雷电灾害易损性综合评估，并结合 GIS 方法对浙江省进行了雷电灾害易损性风险区划，为有针对性做好防御雷电灾害规划提供科学依据.

Vulnerability analysis and risk zoning of regional lightning disaster in Zhejiang province

Based on the lightning disaster investigation data,lightning monitoring data in Zhejiang province from 2007 to 2010,vulnerability analysis and risk zoning of lightning disaster in Zhejiang province are made in this paper.Indicators,such as cloud to ground lightning density,the frequency of lightning disaster,economic vulnerability module,vital vulnerability module,the loss of lightning disaster and the number of casualties,are selected as indexes for risk assessment of regional lightning disaster and comprehensive evaluation of the vulnerability of each city and county in Zhejiang province.Finally,the vulnerability zoning map is made in Zhejiang by means of GIS,which provides scientific basis and valuable reference for the reasonable planning of lightning disaster prevention and reduction in Zhejiang province.
