摘　　要：地闪密度分布图能够反映雷电的活动分布和变化特征,可为电网防雷提供基础资料。编写Visual C++程序,能够自动生成地闪密度分布图和相应的MIF文件,生成的MIF文件可以在MapInfo中转换为MapInfo Tab图,并做进一步分析。这就避免了专业的Mapbasic语言,只需通用的Visual C++语言即可在MapInfo中成图。最后将程序做成动态链接库,节省了系统资源,提高了运行效率。Cloud-to-ground flash density map could reflect distribution of activity and variation characteristics of thunder and lightning, and provide basic data for lightning protection. We developed a Visual C＋＋ program, which is capable of automatically generating cloud-to-ground flash density map and corresponding MIF file. The MIF file can be converted to the Maplnfo Tab diagram by using the MapInfo software for further analysis. It avoids Mapbasic language and only uses general Visual C ＋＋ in the process of map-making based on MapInfo. At last, we make dynamic link library with program, in order to save the system resources and improve the operation efficiency.
