Analysis of characteristics of lightning disaster and risk zoning in Ningbo Area(宁波地区雷电灾害特征分析及风险区划)
Zhejiang Daxue xuebao. Lixue ban, 2014 根据宁波地区ADTD闪电定位系统2010~2012年的地闪监测数据、雷灾资料以及2012年宁波地区人口及GDP数据，选取年平均地闪密度、单位面积雷灾频数、经济损失、人员伤亡、人员易损、经济易损6项指标，在详细分析宁波雷灾分布特征的基础上，采用主成分分析法对宁波各县地区雷灾易损性指标进行综合评价，并利用分层聚类分析法得出：政治经济文化中心的海曙区为雷灾极高易损区，经济发达的江东区以及工业基地镇海区为高易损区，江北区为中易损区，鄞州区、北仑区、象山县、宁海县、奉化市为低易损区，慈溪市和余姚市为极低易损区.
