  1. 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 。
  2. The effect of hydrodynamics on the algal growth rate is mainly studied herein based on the analysis of the algal growth mechanism and the measurement data of the daninghe river which is a branch of three - gorges reservoir, and then an empirical formula of the algal growth rate related with water velocity is proposed for the daninghe river ; which can be used to predict the change status of the eutrophication of the branch when the water velocity is decreased with the increase of water level of the three gorges reservoir

    基於國內外對氣候條件和營養鹽條件對藻類生長速率影響研究成果基礎上,採用機理分析和實際案例分析相結合的方法,重點探討了以流速為表徵要素的水動力條件對藻類生長速率的影響特點,並且以三峽庫區支流大寧河為例,初步建立了流速對藻類生長速率影響規律的經驗關系式,為預測三峽庫區富營養化演變態勢提供基礎,進而為有效防治富營養化提供技術支撐。
  3. The operating principle of electro - hyraulic power pulsed technology, mechanism of purifying eutrophication for lake water body and some experimental results are briefly introduced

    介紹了電液壓脈沖技術的工作原理,電液壓脈沖技術治理湖泊水體富營養化的凈化機理並進行了相關的實驗室實驗。
