根据浙江省2008-2010年ADTD闪电定位仪资料，首次将平均地闪强度引入雷电灾害风险评估中，结合杭州市的人口经济影响和自然地理要素，选取地闪密度、平均地闪强度、人口密度等16个雷电灾害风险评价指标，采用层次分析法计算各要素权重，从危险性、敏感性、易损性和防灾能力建立雷电灾害风险评估模型，分析雷电灾害的综合风险。从雷电灾害综合风险区划图可以看出，总体上雷电灾害综合风险在杭州市西南地区比较低，近海的东北地区则比较高；杭州市主城区、萧山区、余杭区、临安市和近富春江地区是雷电灾害综合风险较高的区域，低风险的区域主要在杭州中西部地区。对杭州市雷电灾害进行了灾度评价，以验证风险区划的正确性，证实区划结果与实际雷电灾害的发生具有较好的一致性。

Based on the thunderstorm day data from Hangzhou City during 1966 to 2010 and the lightning detection data from Zhejiang Province during 2008 to 2010 , and combined with population and economic impacts and natural geographical factors , this study selected the appropriate disaster risk evaluation indexes . This study analyzed the risk of lightning hazard in Hangzhou City ,by the use of ArcGIS spatial analysis and fuzzy comprehensive evaluation method , divided into five risk lightning hazard , and then drew 1 km × 1 km grid of lightning hazard zoning . The evaluation of lightning disaster in Hangzhou City had been made to verify the validity of the risk division , and the lightning hazard division was consistent with the actual lightning disasters .
