摘　　要：对江苏省电力部门和江苏省气象部门的两种不同闪电定位系统记录的地闪资料统计分析,发现电力部门的闪电观测记录明显比气象部门的多,而二者变化趋势基本一致,介绍了经采用剔除不可靠观测记录以及用回击、电流处理方法修正处理后的两套系统探测数据的对比分析发现,电力部门和气象部门的闪电记录相差很小,有关南京地区的闪电月分布、日分布、闪电密度空间分布大抵相符,表明这种对观测结果进行修正的方法是有效的,有利于双方资料的共享与互补。The lightning record analysis of two lightning positioning systems which are owned by Jiangsu electric power department and Jiangsu meteorological department respectively shows that the recorded lightning frequency of the electric power department is more than that of the meteorological department, however, the changing tendency of the two are almost the same. By using some amendment methods such as eliminating the unreliable observation record as well as the method of lightning return stroke and lightning current treatment, the lightning records of the two departments became similar, with their records on monthly and daily lightning distribution almost the same, as well as that on spatial distribution of lightning density, which proves that the amendment methods are effective.
