Abstract：The present study employed a combination of location-based analytics platform(i.e.,ArcGIS)and analytical hierarchical process(AHP)techniques to analyze the lightning risk zoning of Hainan Island.Data used included lightning location data from 2014 to 2020,1 km×1 km gridded GDP data(2019),and 30 m×30 m gridded land use type,elevation,and soil conductivity data(2020).The results indicated that(1)the high-risk lightning zones are predominantly located in the northwest of Hainan Island and the northern part of Haikou City.Medium-risk zones are found across the central and northern parts of the island,while low to very low-risk areas are located in the central mountainous region and the southeastern coastal areas of the island.(2)The central mountainous region,characterized by moderate economic activity and low population density,coupled with the island's distinctive climatic conditions,is less prone to severe lightning hazards.
