基于GIS的广西农业暴雨洪涝灾害风险评估
GIS-based Assessment of Agricultural Flood and Water-logging Risk in Guangxi
摘要
Abstract
By use of natural disaster risk assessment theory and methods and based on remote sensing background data, weather data, geographic information data and socio-economic data, the index system for evaluation of storm rain and flood risk of agriculture in Guangxi is established. Using the AHP method and weighted synthesis, agricultural flood risk evaluation model is worked out. With GIS technology, agricultural flood risk, sensitivity of disaster development environment, vulnerability of disaster-bearing bodies, disaster prevention and mitigation capabilities and integrated risk index in Guangxi are calculated and agricultural flood risk in Guangxi is zoned. Using correlation analysis method, the consequences of flood disasters of agriculture flood disasters and historical data of agricultural rainstorm and flood disasters in Guangxi are compared and verified. The results show that the distribution of results of agricultural rainstorm and flood risk is basically consistent with spatial distribution of flood disaster losses, the strongest risk in the southern coastal area and the lowest risk in the western coastal area.关键词
