Abstract:The correlation between thunderstorm and lightning disaster is analyzed,based on thunderstorm data in past 60 years,lightning data in recent 5 years and lightning disasters in past 10 years of Changzhou.Results show that the occurrence of lightning disaster can not be solely attributed to natural factors like thunderstorm,flash;anthropogenic factors like economic development,population density,and lightning protection level may also influence the occurrence and level of lightning disaster.In the loss caused by lightning,failure of electrical and electronic system accounts for the largest proportion.And the local residents are the most vulnerable to lightning disasters in all industries,which is associated with people's indifference to lightning protection and short of lightning protection device for residential buildings.Combined with actual situation,7 indexes are put forward to evaluate the lightning disaster vulnerability of Changzhou,including thunderstorm days,lightning density,lightning disaster frequency,economic development,population density,vulnerability of economy and population.Based on data about the population,area and economy in all districts of Changzhou from the statistical yearbook of Jiangsu,lightning disaster vulnerability risk of each district is calculated by analytic hierarchy method,and the risk zoning is classified as high risk area(Wujin district),relatively high risk area(Tianning district and Jintan city),middle risk area(Zhonglou district,Qishuyan district and Liyang city) and low risk area(Xinbei district).
