The characteristics and output rules of nitrogen and phosphorus loss of rainfall runoff in farmland of typical plain river - net area were studied through the field survey and the fixed location monitoring of the concentration of nitrogen and phosphorus 摘要通過對研究區降雨徑流中氮、磷濃度的野外實驗和定點監測,研究典型平原河網區的農田降雨徑流氮磷流失特征及其輸出規律。
The main research contents of the paper involve : establishment of real time forecasting system of taihu lake basin ; forecasting method for the tidal levels along yangtze river and hongzhou bay ; model mechanics of flow generation and confluence forecasting ; forecasting model mechanics of flow dynamics in plain river networks of taihu lake basin ; case study of real time flood forecasting and control in taihu lake basin 本文所研究的內容主要概括如下: 1 )太湖流域實時預報調度系統的建立與開發機制; 2 )沿長江及杭州灣潮位預報方法; 3 )太湖流域產匯流預報模型機理; 4 )太湖流域平原河網水動力學預報模型機理; 5 )太湖流域實時洪水預報與調度實例研究。
The main features in the study of flood forecasting and control system are as follows : ( 1 ) runoff generating and confluence theory and hydro - dynamic method are adopted to predict the water level of taihu lake and key nodes , the basin wide forecasting and control system with the function of real time correction has been first established in plain river network to meet the complicated flow conditions of taihu lake basin and to enhance the reliability of forecasting results ; ( 2 ) according to the rainfall in foreseen period multiple schemes can be made in the forecasting model and adjusted with time , which overcomes the errors caused by the uncertain rainfall in the foreseen period so as to make the forecasting results approach reality 本文所研究的預報調度系統有如下特點: ( 1 )本系統采用產匯流理論和水動力學方法預報太湖及重要節點水位,首次在平原河網地區建立了具有實時校正功能的全流域預報調度系統。以適合太湖流域復雜的水力條件,增強預報的可靠性; ( 2 )預報模型可以根據預見期降雨量進行多方案預報,并隨時間推移,可以實時進行調整,克服由于預見期降雨不確定引起的誤差,使預報結果更接近實際。
