摘　　要：通过对闪电频次、闪电强度、人口、经济、爆炸火灾危险场所分布、地形地貌、海拔、历史雷灾等多种资料统计,形成1 km × 1 km栅格数据,建立风险指数模型,使用层次分析法确定指标权重,利用GIS进行绘制出图,最后得出区域内雷电灾害风险,结果表明:风险区划的结果是各指标综合作用的结果,爆炸火灾危险场所分布对雷电灾害风险区划结果是有影响的。Based on the statistics of lightning frequency, lightning intensity, population, economy, distribution of explosion and fire hazard areas, topography, altitude, historical thunderstorm and other data, it formed 1 km × 1 km grid, and established the risk index mode. Then the index weight is determined by AHP. GIS is used to draw a map, and finally, the lightning disaster risk in the region is determined. The results show that the risk is the result of the comprehensive effect of various indicators, and the distribution of explosion and fire hazard areas has an impact on the results of lightning disaster risk zoning.
