The Lightning Disaster Risk Zoning Based on MultiSource Data in Shenzhen

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 highrisk areas are mainly in Longgang and Baoan districts. The general-risks areas are mainly in Kwai Chung and Dapeng Peninsula in the east.
