摘要
2010—2011年对北京市怀沙河流域的水质理化指标进行了监测,根据监测结果对怀沙河流域的水环境现状进行了模糊评价。评价结果显示,在调查期间,怀沙河流域上游和中游的水质多数属于Ⅰ~Ⅲ类水,在怀沙河流域的下游水质多属于Ⅳ~Ⅴ类水,从隶属度来看,主要是总氮、总磷污染比较严重。
The main physicochemical factors were monitored in Huaisha river basin in Beijing from 2010 to 2011,and the water quality was evaluated by means of fuzzy evaluation based on the monitoring results. The evaluation results showed that the water quality in the upstream and midstream was mostly levelⅠ- Ⅲ,but the water quality in the downstream was mostly level Ⅳ- Ⅴ. In consideration of the membership degree,the total nitrogen（ TN） and the to- tal phosphorus（ TP） pollution were serious in Huaisha river.
