摘 要:通过对大冶湖流域的面源污染进行系统调查,分析了其污染特征和成因。结果表明,农村生活产生的化学需氧量、总磷和总氮量均最大;水产养殖排放的总磷和总氮最大;对大冶湖流域水环境污染影响较大的地区是阳新县所辖的3乡镇和1开发区、金山店镇和还地桥镇。农业生产技术落后、农村环保设施薄弱、超面积围网养殖、农民环保意识淡薄,是造成面源污染的主要原因。针对流域面源污染现状,提出了相应的治理对策,为治理大冶湖流域污染提供可靠的依据。By system investigation of non-point source pollution in Daye Lake basin, the pollution characteristics and causes were analyzed. The results showed that the biggest production of COD, TP and TN were from the rural life ; aquaculture discharged the biggest loads of TP and TN ; the areas larger impacting water environment of Daye Lake basin were in three jurisdiction towns and one industrial zone of Yangxin County, Jins- han Town and Huandiqiao Town. The main causes of non-point source pollution were backward technology of agricultural production, weak protec- tion infrastructure in rural environmental, super net breeding area, and farmers' weak environmental consciousness. According to current situa- tion of watershed non-point source pollution, the corresponding countermeasures were put forward to provide a reliable basis for controlling pollu- tion in Daye Lake basin.
