The model considered the natural conditions,social economic conditions and other factors,and the main assessment factors were selected,containing ＂ flash density,lightning current intensity,annual thunderstorm days,lightning disaster frequency,construction area per capita and GDP per capita＂,in order to establish the evaluation model,and divide the level of risk. The results showed that the lightning risk in Meizhou area roughly had the trend of ＂ center higher than all-around,the south higher than the north,the west higher than the east＂. High-risk area was in the most region of Meijiang District and central region of Meixian District,and Wuhua County was next high-risk area. Xingning City and Fengshun County were medium risk areas,most of the other were low risk area. The result of regionalization was consistent with the actual situation,and the evaluation method was scientific and effective. Through the analysis of the lightning risk zoning,this paper could provide a scientific basis for the lightning protection and disaster reduction in the region in the future.展开更多
