中文摘要：

根据自然灾害风险评估理论，利用地闪密度、雷电流强度分布、土壤、海拔、地形起伏、社会经济人口数据以及雷电灾害数据，采用熵值法、百分位法、自然断点法，从致灾因子危险性、承灾体暴露度和脆弱性等方面进行分析，得出了基于多源数据的深圳市雷电灾害风险区划结果。区划结果表明，深圳市雷电极高风险区主要分布在深圳中西部，高风险区主要分布在宝安区和龙岗区的大部份区域，一般风险主要分布在东部的葵涌、大鹏半岛等地。

Abstract：

In this paper, according to the natural disaster risk assessment theory, the lightning disaster risk zoning in Shenzhen is obtained after the analyses of hazard factors, the exposure and vulnerability of hazardous body. The data used includes the cloud-ground flash density, lightning current intensity distribution data, soil, elevation, topographic fluctuations, socio-economic population and lightning disaster data. The methods used include entropy method, percentile method and natural breakpoint method. The results show that the extremely high-risk areas are mainly in the central and western parts of Shenzhen, and the high-risk areas are mainly in Longgang and Baoan districts. The general-risks areas are mainly in Kwai Chung and Dapeng Peninsula in the east.
