Abstract
In order to define the degree of lightning disaster risk of different areas and counties, taking Xiuyan County in Anshan, Linghai City in Jinzhou and Dashiqiao City in Yingkou of Liaoning Province as examples, this paper uses lightning locator data and geographic information data, adopts normalization method and natural break point method, and considers two evaluation indexes: the risk of disaster causing factors and the sensitivity of disaster causing environment. The lightning hazard zoning model was established by selecting ground lightning density, ground lightning intensity, altitude, topographic relief and soil electrical conductivity, and the lightning hazard zoning map was drawn. The results showed that the northwest and northeast of Xiuyan County, the northwest of Linghai City and the southeast of Dashiqiao City were high to very high risk areas, and the other areas were low risk areas and general risk areas.
