Abstract: Distribution characteristics of lightning damage vulnerability in Beijing area are researched by establishing the evaluation model refer to the disaster factors’ hazard, sensitivity of disaster environment, vulnerability of bearing body. The data of meteorological observation, geographic information, and social surveys are used for analytic hierarchy process (AHP) and hierarchical statistics. The results show that the maximum value of disaster factors is distributed in Huairou, Miyun and Mentougou. The low sensitive areas of the disaster environment are mainly distributed in the areas where the buildings with reinforced concrete structure. The most vulnerable area is distributed in the East, the West, Haidian and Chaoyang. In addition, regional distribution of lightning damage vulnerability is relatively scattered in Beijing area. The highest-risk areas are distributed in the East, the West, Yanqing and Miyun, the sub-highest-risk in Fengtai, Mentougou, Fangshan and Huairou, these areas account for more than 62% of Beijing.
