Abstract Lightning disaster is one of the most important nature disasters.It has an important meaning to found the lightning disaster risk zoning of the area.In this paper,using the number of thunderstorm days in a year of Jilin province between 1977 and 2012,and lightning disaster statistics between 2002 and 2012,referring to the population density of Jilin province,social and economic characteristics like city development,selecting the number of thunderstorm days,lightning disaster frequency,economic vulnerability modulus and life vulnerability modulus as evaluation index of the lightning disaster risk,the risk assessment formula to divide the risk grade of lightning is established.The results show that the city of Changchun,Siping,Tonghua and Liaoyuan are strong risk regions of lightning disaster,the city of Songyuan,Jilin,Baishan and Baicheng are high risk regions of lightning disaster,and the Yanbian Korean autonomous is a medium risk region.
