Research on Natural Disaster Risk Assessment and Optimization Strategy of Traditional Villages in Hebei Province Based on AHP-Entropy Weight Method
Traditional villages have high historical preservation value,with a gathering of historical and characteristic buildings.However,they are mostly located in remote areas,with a lack of disaster prevention infrastructure,inconvenient rescue work,and are prone to natural disasters with severe damage.Therefore,conducting pre-disaster natural disaster risk assessment has become an important foundation for protecting traditional villages and reducing disaster losses.Taking the traditional villages in Hebei Province as the research object,based on the AHP-entropy weight method,a comprehensive risk assessment system of natural disasters such as rainstorm,flood,drought,geological disasters and other typical disasters is constructed.The spatial division of natural disaster risk levels in traditional villages in Hebei Province is realized by using GIS technology.Relevant optimization strategies are proposed to provide a basis for promoting the protection and disaster prevention and control of traditional villages in Hebei Province.
