摘要
洪涝灾害损失评估是我国洪涝灾害救助中非常重要的环节,对于灾害科学研究和救灾工作具有重要的理论和实践意义。根据洪涝灾害损失与气象水文要素之间的相关分析,建立了历史气象水文要素和受灾面积、财产之间的关系模型,利用财产损失率和固定资产本底数据,评估洪涝灾害造成的直接经济损失,用于灾前预评估和灾后快速评估。以淮河流域中游安徽段为例,选取2007年淮河洪水进行了分析,评估结果与实际上报数据进行了比对,表明该评估方法可行,评估结果可靠。
The flood and waterlogging disaster loss assessment is a very important component for the disaster relief work, which has important theoretical and practical significance for the research of disaster and its relief. According to the correlation analy- sis between the flood disaster loss and meteorological and hydrological elements, a correlation model between the area and prop- erty of flood disaster loss and historical meteorological and hydrologic factors was developed. The property loss rate and back- ground data of permanent assets were used to evaluate the direct economic losses caused by flood disaster, which are useful for the pre-disaster preliminary assessment and post-disaster rapid assessment. In this paper, the flood of the middle reach of Hua- ihe River in Anhui Province in 2007 was analyzed, which provided similar assessment results of flood disaster loss with those re- ported data in reality. Therefore, the evaluation method is applicable and reliable.
