基于变权理论的河北省洪涝灾害风险评估研究
Flood Disaster Risk Assessment in Hebei Province Based on Variable Weight Theory
摘要
Abstract
Disaster risk assessment is an important means to reduce disaster loss.Following the risk system theory and combining the disaster characteristics and economic development of Hebei Province,four dimension in-dicators are selected as disaster causing factor risk,disaster-induced environmental sensitivity,disaster-bearing body vulnerability and disaster prevention and reduction ability.By using entropy weight method to determine the constant weight of indicators,flood disaster risk assessment index system of Hebei Province is established.Based on meteorological and hydrological data,landform and geomorphology data,social and economic data,the state variable weight vector conforming to the characteristics of flood disaster risk assessment is constructed,and the flood disaster risk assessment model of Hebei Province is established to carry out refined risk assessment for county units in Hebei Province.The results show that the flood disaster in Hebei Province was high in the eastern coastal counties,medium in the southern plain and low in the northern mountainous counties.关键词
