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 analysis between the flood disaster loss and meteorological and hydrological elements, a correlation model between the area and property of flood disaster loss and historical meteorological and hydrologic factors was developed. The property loss rate and background 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 Huaihe River in Anhui Province in 2007 was analyzed, which provided similar assessment results of flood disaster loss with those reported data in reality. Therefore, the evaluation method is applicable and reliable.
