摘　　要：基于2012—2013年江西省闪电定位系统资料和2011—2013年雷电灾害统计资料,运用Arc Gis空间分析技术,得到江西省雷电时空分布特征,并选取雷电灾害频数、雷电密度、生命易损模数和经济易损频度作为江西省各地级市雷电灾害易损性评估指标。分析结果表明,江西省雷电活动集中发生在4—9月份,尤其以夏季最多,雷电多发时段为14:00—21:00;全省地闪密度较大区域常位于山脉迎风坡和河流附近;上饶市、九江市、南昌市和鹰潭市为江西省雷电灾害高易损区。Based on 2012—2013 lighting detection data and 2011—2013 lighting disaster statistical data, the Arc GIS was used to analyze the temporal and spatial distribution of lightning activity, lighting disaster frequency, lightning density vital vulnerability module and economic vulnerability module were selected as assessment indices of risk zoning of regional lightning disaster. The result shows the lightning in Jiangxi mostly occurred in the period from march to September,especially in summer,and the lighting activities occurred frequently in the period from 14：00 to 21：00. High lighting density occurred on the windward slopes of mountain and nearby the river. Jiujiang, Nanchang, Yingtan and Shangrao are the maximal vulnerability area.
