摘　　要：基于模糊评价和层次分析法(AHP)开展大伙房水库水质评价,选择反映大伙房水库入库、库区、出库的7个水质监测断面7项水质污染因子监测值为对象开展分析。结果表明:2010年大伙房水库主要受氮磷营养盐污染;入库河流中浑河的污染程度最高;库区水质主要为Ⅱ类,出库水质为Ⅱ类,水质安全、可靠。从浑73、浑37、浑7三断面2005—2010年水质监测值变化来看,库区污染得到了有效控制,库区水质稳定提升。It evaluated the water quality of Dahuofang Reservoir based on fuzzy evaluation and AHP method and selected seven water pollution fac- tors as the object, which came from seven monitoring sections of Dahuofang Reservoir. The result demonstrates that Dahuofang Reservoir is mainly affected by nitrogen and phosphorus pollution in 2010. Hunhe River is the most seriously polluted storage among the reservoir inflow. The water quality of reservoir is mainly Ⅱ grade. The water quality of reservoir outflow is Ⅱ grade, which is safe and reliable. The research also selects the Hun73, Hun37 and Hun7 water quality monitoring sections as the study object. According to the change of water quality monitoring values in the period of 2005 - 2010, it is concluded that the reservoir＇ s pollution has been effectively controlled and the water quality has been improved stably.
