摘　　要：牛栏江—滇池补水工程是滇池流域及周边地区的水资源综合利用工程,是增加滇池生态环境水量,改善滇池水资源质量的重要工程,对于保障现代新昆明建设和云南省经济社会可持续发展具有重大战略意义。然而近年的监测结果表明,牛栏江流域水资源质量有下降趋势。在以往的研究中曾提出面源污染是主要污染源。通过研究,发现牛栏江水污染物以总磷(TP)为主,且主要集中在七星桥断面以上;总磷(TP)污染主要来自于工业排放。并据此提出水污染治理的水资源保护对策。水环境治理措施和水质监测结果验证了结果的可靠性。The Niulanjiang River-Dianchi Lake Water Supplement Project,as a synthetic utilization project of water resources in Dianchi Lake basin and surrounding areas,is crucial for increasing the ecological and environmental water supplement and improving the quality of water resources in Dianchi Lake.As a consequence,this project plays a great strategic role in ensuring the construction of the new Kunming city and the economic and social sustainable development of Yunnan Province.But the monitoring results of recent years suggest that the quality of water resources in the Niulanjiang River has entered in a downtrend.Non-point source pollution has been considered as the major pollution sources in previous studies.This research shows that the major pollutant in the Niulanjiang River is total phosphorus,which mainly comes from the industrial discharge,most being found at the Qixingqiao Section.And based on the research,this paper also proposed some water resources protection countermeasures to control the water pollution.The reliability of the conclusion has been proved by the result of water environment governance measures and water quality monitoring.
