| 摘要: |
| 基于海南岛 2014—2020年闪电定位数据、2019年公里网格 GDP及人口数据、2020年 30 m网格土地利用类型、高程数据和土壤电导率数据，采用 ArcGIS软件，运用层次分析法(Analytic Hierarchy Process)，分析了海南岛雷电灾害风险区划。结果表明：(1)海南岛的雷电高风险区集中在海南岛西北区域以及海口市的北部；中风险区则分布在海南岛中部地区和北部地区，次低和低风险地区则分布在海南岛的中部山脉地区和东南边沿海地区；(2)海南岛中部山脉地区人口稀少，经济发展水平一般，加上海南岛本身气候特殊，不易形成严重的雷电灾害。 |

| 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. |
