  6. In this passage, author has studied the quota of irrigation that can make water used economically for various plants, if the irrigation quota can be lowered from 6795 m3 / a to 4500 m3 / a during the processes of irrigation, there will be a saving water amount of 3. 386million m3 / a, in shiyang river basin. there is no doubt that we can open the second source of river water that can provide the possibility of transporting 300 million m3 / a water amount to lower reaches of the river. in this paper, there are some analysis and prospects for the future situation of supply and demand of water resources in 2010

    民勤水資源減少的主要原因是人為因素，如全流域人口增加、中上游耕地面積擴大，用水量增加，造成灌區重心上移；沒有樹立可持續發展觀，在經濟中搞短期行為；對石羊河流入民勤水量不斷減少、地表水、地下水轉化活躍、生態用水問題突出等方面進行了分析論證；對目前開發利用現狀、供需狀況進行了較為詳細的計算和評價；通過對各種農作物節水灌溉定額的研究，若從現狀灌溉定額6795m ~ 3 ha降低到4500m ~ 3 ha實施灌溉，石羊河流域將節水3 . 3867億m ~ 3 ，這無疑于開辟了第二水源，提供了向下游調水3億m ~ 3的可能性。
  7. At the same time, using the results of model, the paper provides the optimization irrigation quota and the aim of high yield and high benefit based on the principle that the net benefit of unit water is highestusing the model, we can reasonably distribute the irrigation water for spring - wheat during growing period on the condition of different irrigation quota. through evaluating the comparative yield by the model, the paper gains that the reduction of spring - wheat output is biggest when the irrigation quote is between 100 and 200. the thesis also gains that the corresponding economic irrigation quota is 170 - 120m3 / 667m2. above results can provide scientific reference for irrigation water optimization distribution for crops in the individual irrigation area and the programming of irrigation district

    在現有的生產條件下，可以利用模型在不同的灌溉定額下對春小麥生育期灌水進行合理的分配，並可以利用模型進行作物相對產量的評估，得出當灌溉定額在100 m 200范圍內時，春小麥的產量下降幅度較大，最後得出相應的經濟灌溉定額為170 120m ~ 3 667m ~ 2 ，為今後河套灌區各灌域多作物灌溉水量最優分配以及灌區的規劃設計方面提供了科學參考依據。
