摘要： 为了掌握雷电发生规律、防御和减轻雷电灾害，以菏泽地区2007—2013年地闪资料为基础，详细分析其时空分布特征。结果表明，菏泽地区地闪主要受下垫面影响，空间分布差异明显，水体附近地闪密度较大。地闪时分布呈多峰状，2个最大的峰值出现在5时和11时左右。负地闪的雷电流强度分布和总地闪的吻合度很好，地闪密度和强电流分布高值区一致，分布在东明县南部和曹县西北部。

Abstract: The paper aims to understand the occurrence law of lightning, and the mitigation of lightning disasters. Based on the cloud-to-ground lightning data in Heze during 2007-2013, the authors analyzed the spatio-temporal distribution characteristics of cloud-to-ground lightning. The results showed that: cloud-to-ground lightning in Heze was mainly affected by underlying surface and the spatial distribution was significantly different, lightning had a greater density near water; the moment distribution of cloud-to-ground lightning was multimodal, two of the largest peak appeared at around 5 am and 11 am; the lightning current intensity distribution of negative cloud-to-ground lightning matched the total flash well; the density of cloud-to-ground lightning and high values of high current density distribution were consistent, which was located in southern Dongming and northwestern Caoxian.
