  1. According to the concept of available water supply, the calculation methods about available water supply of the large scale reservoir are studied and the concrete procedures of the long - series regulation method are proposed. through the calculation of the monthly natural runoff every year, water incomes under present engineering status, and the long - series dynamic water usage regulation of the 32 large scale reservoirs in shandong province, available water supply under assurance rates of 50 %, 75 % and 95 % are obtained. according to the analysis of runoff characteristics of each reservoir ( multi - year mean runoff depth and runoff coefficient ), the relationship between water supply incomes under different assurance rates for current year and the year of 2010, the reservoirs with water supply potence are given

    根據對可供水量概念的理解,本文對大型水庫可供水量的計算方法進行了探討,提出了採用長系列調節計算的具體方法;通過對山東省32座大型水庫的歷年逐月天然徑流量、現狀工程情況下來水量、長系列變動用水的調節計算等多個步驟,得出了各水庫50 、 75 、 95三種保證率的可供水量計算成果,並對每個水庫的徑流特性(多年平均徑流深及徑流系數) 、全省大型水庫現狀年及2010年的不同保證率的可供水量與來水量的關系進行了分析與研究;分析提出了具有供水潛力的水庫。
  2. This will provide concrete reference for parameters values which mainly depend on the experiences. according to the selected bp model and related water table depth records and other information, the annual and monthly mean water table depth trends in the future planning year ( 2005, 2010 ) are forecasted on condition that water saving reconstruction projects are accomplished in the larger scale experimental zone ( jiefangzha ) of hetao irrigation district

    在此基礎上根據黃河河套灌區多年的水文、氣象和地下水信息,對一個大尺度區域的多年年均地下水埋深變化進行了bp模型的模擬與檢驗,預測了灌區節水工程實施后未來規劃水平年( 2005 , 2010年)年平均、月平均地下水位下降的動態。
