Abstract: Using lightning disaster data from 2005 to 2014 and ADTD (Active Divectory Topology Diagrammer) lightning location data from 2008 to 2014 in Beijing,the characteristics of lightning disaster and lightning were analyzed based on statistic approaches.The results show that there are totally 532 cases of lightning disasters from 2005 to 2014,with an average of 53.2 cases per year in Beijing.The annual direct economic losses are more than three million yuan.The lightning disaster mainly occurs during June to August,especially in June,mostly happening at 17:00 to 23:00,especially at 19:00.The spatial distribution of lightning disaster demonstrates that there is a higher value in the urban and southern parts and lower in the suburb and northern parts.The lightning disaster primarily happens in the civilian,business,transportation,electric power,communication,petrochemical,finance,and tourism industries.The victims of lightning disaster generally include office (54.12%) and household (30.47%) electronic appliances.The lightning disasters usually focus on the living,office and production spaces.The temporal distribution of lightning disaster is basically consistent with that of the lightning,while the spatial density distributions of them are a little different.
