Lightning Hazard Assessment in Hainan Island Based on Hierarchical Analysis Model

Abstract

According to the lightning monitoring data of Hainan Province from 2011 to 2020,eight cities in Hainan Province were selected as the evaluation units.Combined with the statistics of population, lightning weather, economic characteristics and land area of each city, the population density, GDP value, thunderstorm days, illiteracy level and lightning frequency (density) of each city were selected as risk assessment indicators, and the evaluation model was established by AHP. Get the weight of each index and calculate the lightning risk disaster index of each city according to the numerical value of each index of each city. After consulting relevant materials, it is found that the construction of communication base stations will also induce lightning disaster accidents, and the evaluation results of each city will also be affected by the number of communication base stations in the region, so the correctness of the results also indicates the rationality of the evaluation method.
