摘　　要：根据2011—2014年滇池水质监测资料,分析了牛栏江—滇池补水工程实施前后滇池外海中总磷和总氮的变化趋势及变化原因。结果表明:引牛栏江水入滇池后明显地降低了滇池中总磷和总氮含量,减轻了滇池富营养化程度,从而有效改善了滇池的水质。The changes of the concentrations of total nitrogen and total phosphorus before and after the construction of the water supply engineering from Niulanjiang River to Waihai of Dianchi Lake was analyzed as well as the reasons based on the water quality monitoring data from the year of 2011 to 2014.The results showed that the water from Niulanjiang River obviously decreased the concentrations of total nitrogen and total phosphorus and alleviated the eutrophication degree of Waihia and improved the water quality of Dianchi Lake.
