The results indicated that national lightning disasters showed increasing trend in recent 11years, the lightning peak period was from June to August of each year. Geographical distribution of lightning disasters in China mostly concentrated in Southern and Eastern coastal most severe lightning accidents in China appeared in electrical power industry. The ratio of building damage, power failure, fire and explosion due to lightning occurred in China was about 9:5:3 in recent years. The ratio of deaths and injuries due to lightning is 1:1. Finally, use the gray relational method to forecast the lightning disasters economic losses of China.
