• 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
