摘　　要：跨区域跨流域调水是我国水资源优化配置的重要组成部分之一。太湖流域内水流缓慢,环境容量低,引水清污成为太湖流域改善水环境质量的手段之一。在污染源难以得到有效治理的条件下,引水使得江河原水中污染物发生二次迁移,对流域水环境质量产生污染风险。基于三角模糊数原理以及a-截集技术,选取氨氮关键水质参数,评估太湖流域典型调水试验受水区水质污染风险程度,从而为太湖流域水利工程的科学调度提供理论依据。Inter-basin water transfer is an important component of optimal deployment of water resources. Slow velocity of plain river networks leads to little water environmental capacity in Taihu drainage basin. Diverting water to flush out pollutants becomes a solu- tion to improving water environment. Combining failure probability with calamity consequence of inter-basin water transfer projects, the risk assessment system of water transfer project has been proposed. Then, ammonia nitrogen as triangular fuzzy numbers is uti- lized to assess the recontamination risk of water diversion experiment in Taihu Lake. A case study shows that the models provided here are quite suitable for pollutants recontamination risk assessment of typical transferring water experiment.
