Risk assessment of Karst waterlogging disaster in Debao County of Guangxi
摘要
Abstract
The paper used the disaster risk evaluation model based on ArcGIS technology and analytic hierarchy process to conduct risk assessment for karst waterlogging disasters in Debao county of Guangxi in order to provide important scientific basis for the prevention and treatment of karst waterlogging.By comparing the factors of Debao country such as rainfall,socio-economic and natural environment,it used AHP to determine the weight each factor,and then made use of ArcGIS to get the hazard and vulnerability zoning map of karst waterlogging disaster.The results indicated that high risk areas are mainly located in Chengguan town of densely-populated areas.The secondary high risk areas are mainly located in the northern area of the county where agricultural acreage is widely distributed.The waterlogging disaster risk in the eastern and western of Debao county is low.关键词
