  4. 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

    本文調查了千島湖流域的自然資源和農業生產情況，研究了典型坡地降雨徑流中的氮、磷污染物的輸出規律，利用annagnps模型估算流域農業非點源污染物輸入負荷，並在千島湖內設點采樣，對水質理化指標和浮游植物群落進行系統的研究，得出以下結論： 1989 2001年間的水環境常規監測資料統計分析表明，有毒物質和重金屬濃度長期在監測下限內， no _ 2 - n 、 no _ 3 - n 、 nh _ 3 - n年平均濃度均符合類標準，但湖泊水庫特定項目tn和tp濃度分別為超類和類，呈嚴重超標狀況，湖區主要污染因子是將導致富營養化的物質tn和tp 。
  5. When the concentration is low, 0 - 6 mg / kg, the content of cadmium in the root of alfalfa is lower than in the stern and leaf, but two times higher than the forage hugiene standard of our country. when the concentration is higher than 10mg / kg, the content of cadmium in the root is 20 times higher than the standard, but the content of cadmium in the soil decreased obviously, so alfalfa of this condition is the best alternative for renovating polluted soil. when 200mg / kg znic is added, the poison of cadmium is decreased dramatically with the grow time increasing, the cadmium effect on living number decreased

    盆栽試驗中鎘對紫花苜蓿的出苗率、根、莖的生物量的影響與種子的萌發呈現同一規律；鎘在紫花苜蓿體內的含量也與土壤中鎘濃度有關：低濃度0 ? 6mg kg時，紫花苜蓿根部的鎘含量低於莖、葉中的鎘含量，但己超出我國飼料衛生標準2倍，濃度大於10mg / kg時，根部的鎘含量比飼料衛生標準高出20倍，而土壤中鎘含量大大降低，所以此時的紫花苜蓿是修復鎘污染土壤的較好的植物；當加200mg kg鋅后，鎘的毒害作用明顯減小，隨著生長時間的增長，生物量受鎘的影響也在減小，同時紫花苜蓿體內的鎘含量大幅度降低，有些己降到飼料標準以下。
