基于GIS的陕西省洪涝灾害风险评估及区划
Assessment and Regionalization of Flood Disaster Risk in Shaanxi Province Based on GIS
摘要
Abstract
Based on the fact that flooding is frequent in Shaanxi Province, we can recognize that disaster risk assessment is helpful in reducing casualties and financial loss, which include rainfall record in 84 Forain Smart Stations in Shaanxi Province, the historical flooding trace from 1950 to 2000, and the latest social and economic message of Shaanxi Province in 2015 to scientifically and systematically carry out the work of disaster risk assessment and prediction.We adopt the way of Analytic Hierarchy Process (AHP) to explore risks of flooding in fatalness, exposure, and vulnerability and disaster prevention and mitigation capacity.The four major factors to poor standardization of sub factors data processing, comprehensive weighting method is used to calculate the index coefficient, and combined with the Arc-spatial analysis function of GIS, flooding factors of districts in Shaanxi province.The results show that the frequent flood are mainly distributed in Shaanxi province Ankang municipality;Weinan, severe exposure in Xi'an, Xianyang;extreme vulnerability in Yulin and Xi'an;advanced ability of disaster prevention and mitigation in Xi'an;Comprehensive risk in Ankang municipality, Weinan, Xianyang.Flooding is closely related to the climate, topography and social economy.The results show that the divisions are identical to the flooding happened in recent decade's years, so has some reference value.关键词
