GIS-based analysis of flood disaster risk in LECZ of China and population exposure

China's Low Elevation Coastal Zone (LECZ) is prone to flood, where the population exposure, death risk and economic loss risk are very high. We apply an ArcGIS environment to combine the gridded data of the world population (GPW) and flood disaster risk data from Hotspots and Chinese administrative division to analyze the spatial distributions of flood occurrence frequency, death risk, economic loss risk and the population exposure characteristics at the provincial level in East China's coastal lowlands. The spatial patterns of the flood risk and population exposure in the provincial administrative regions are presented, the prone disaster areas and the related risk factors, social and economic vulnerabilities were identified. This work provides basic information for understanding and mitigating the flood risk in LECZ.
