Abstract:
By means of lightning disaster data for nearly six years and annual thunderstorm data for 40 years, considering the background of the geographical environment and climate, the vulnerability of thunder disasters in Dalian is assessed, in which six indicators are selected, calculated by using AHP, and passed the significance test. The results show that Jinzhou has the highest risk; Wafangdian is the second, Dalian, Pulandian, and Zhuanghe are the next; Lushun has relatively low risk. It is showed that the risk assessment for regional lightning disasters is not only depended on the number of thunder storm days, but also on the economic development, the density of population, the history of disasters, as well as the weights of different indexes. The assessment analysis of regional thunder storm disasters with AHP can reduce the impact of man induced factors effectively.The results provide a basis for lightning protection and disaster reduction.
