• As the agricultural nfs is the most important factor for water environmental deterioration and lake eutrophication in china , more and more scientists and technologists focus on the control countermeasurc and pollution mechanism of agricultural non - point source ( nfs ) . based on the investigation of natural resource and agricultural distribution , the loss rule of nitrogen and phosphorus in the typical land of qiandao lake watershed and distribution rule of the phytoplankton and physico - chemical characteristic in the lake were studied , and the input loading of nitrogen and phosphorus was also calculated by the annagnps model in this thesis . according to the routine monitoring data of the water environment in qiandao lake from 1989 to 2001 , the concentrations of toxic substance and heavy metal were under the monitoring limit , but the total nitrogen ( tn ) and total phosphorus ( tp ) were much higher than the criterion for lake and reservoir
  本文调查了千岛湖流域的自然资源和农业生产情况，研究了典型坡地降雨径流中的氮、磷污染物的输出规律，利用annagnps模型估算流域农业非点源污染物输入负荷，并在千岛湖内设点采样，对水质理化指标和浮游植物群落进行系统的研究，得出以下结论： 1989 2001年间的水环境常规监测资料统计分析表明，有毒物质和重金属浓度长期在监测下限内， no _ 2 - n 、 no _ 3 - n 、 nh _ 3 - n年平均浓度均符合类标准，但湖泊水库特定项目tn和tp浓度分别为超类和类，呈严重超标状况，湖区主要污染因子是将导致富营养化的物质tn和tp 。
