摘　　要：为了更全面地了解LD-Ⅱ和ADTD型闪电定位资料的准确性,利用安徽省2010年3—9月两套闪电定位系统监测到的资料,对比分析安徽省雷电活动规律,结果表明:两套资料在地闪总数、地闪时间变化、地闪空间分布、雷电流极性和强度等方面都存在较大的差异,LD-Ⅱ型闪电定位系统积累的资料时间较长,但ADTD型闪电定位系统在地闪空间分布、雷电流极性和强度的探测方面准确度更高.与雷灾资料对比发现,ADTD型闪电定位仪监测到的闪电记录距离受灾点较近、误差较小.This paper intends to compare the accuracy of the LD-Ⅱ and ADTD lightning location data.Based on the LD-Ⅱ and ADTD lightning location data from March to September of 2010,lightning characteristics in Anhui province was analyzed.The result shows that there are many differences in monthly variation, daily variation, lightning density and intensity of lightning current between the two lightning location systems. LD-Ⅱ has the longer observation time, while ADTD has a higher degree of accuracy in lightning density and intensity of lightning current.Compared with the data of lightning disaster, ADTD lightning location system is more accurate in lightning positioning.
