随着全球洪水灾害的在近几年的不断猖獗,防洪工程的研究,特别是防洪工程的经济评价研究显得愈加重要。因此,有必要通过对具体的洪灾覆盖区的脆弱性评价,建立脆弱性评价模型,确定脆弱性,并针对是否需要进行防洪工程的建设,从脆弱性和工程经济综合的角度,提出对防洪工程的经济评价。 With the continuous flood of global flood disaster in recent years, the research of flood control engineering, especially the economic evaluation of flood control project, becomes more and more important. Therefore, it is necessary to establish a vulnerability assessment model to determine the vulnerability of the specific flood cover area, and to determine whether the need for flood control projects, from the perspective of vulnerability and engineering economy, put forward the flood control project Economic evaluation.
