摘要
为解决评价指标与洪灾风险的不确定性关系,将集对分析理论应用于洪灾风险的评价中,同时为考虑等级标准边界的模糊性引入置信度准则,以北江流域为例,建立了集对分析评价模型,获得了北江流域洪灾风险危险区具体分布状况,评价结果与实际情况吻合,验证了模型的合理性。
In order to solve the problem of uncertain relationship between the evaluation indexes and flood hazard risk, set pair analysis （SPA） theory is adopted to evaluate the comprehensive flood hazard risk. Considering the grade standard of boundary ambiguity, confidence is introduced to establish the model of flood hazard risk evaluation, Taking Beijiang River Basin as a case study, the specific distribution of high risk which can better reflect the actual situation of flood hazard is obtained and the result validates the rationality of the presented model.
