The Lightningprone areas in Anhui are divided by the natural breakpoint method in use of the twodimensional ADTD lightning location data after the quality control from 2010 to 2016 Results show:(1) The high lightningprone areas were mainly distributed in Chizhou, Tongling, Wuhu, the middle east part of Xuancheng, eastern Chuzhou and Lu’an, western Anqing, and some parts of Huangshan; the medium lightningprone areas were mainly distributed in south of the Huaihe river, such as Chuzhou, Ma’anshan, most parts of Anqing and Lu'an City, western and southern Hefei and Xuancheng; the general lightningprone areas were mainly distributed near the areas along the Huaihe River and north of Huaihe river, such as Suzhou, Huaibei, Bozhou, Fuyang, Huainan, most parts of Bengbu and middle east of Hefei. (2) The lightning current intensity is divided into three levels by using the percentile method. The lightning densities of different intensity levels were generally high in south and low in north in Anhui, but in some areas there is bigger difference, and the distribution features of the first or second intensity levels are relatively close. (3) Terrain factors have great influence on lightning activities. The higherlevel lightning densities were found in the Dabie Mountain area, southern Anhui mountain area and eastern Anhui hilly area than in the areas north of the Huaihe River. The positive correlation between lightning density and river network density is found in the areas south of the Huaihe River; however, there was no significant correlation between lightning density and river network distribution or soil conductivity in the area north of the Huaihe River.
