| 摘 要： | 黄河灌区年均用水量占黄河用水总量的90%左右。受经济条件、灌区设施、管理手段等多种因素制约,灌溉水浪费严重,灌溉水利用水平较低,一般不足0.5,更加剧了黄河水资源短缺的矛盾。根据黄河灌区用水现状,提出了节水潜力的概念和节水潜力的分析计算方法,对黄河干流大型自流灌区的节水潜力进行了分析。

| Abstract: | Irrigation districts are the major water consuming part in the Yellow River,which volume of annual average water using takes up about 70% of the aggregate water using of the whole basin.Be restricted to economical condition,installation of irrigation districts and management method and so on,the irrigation water badly wastes and the water utilized coefficient is lower,general under 0.5.So the conflict of water resource shortage is exacerbated more.According to the current water using condition of the Yellow River irrigation districts,this paper puted forward the concept of water saving potential and its corresponding analyse and calculate method,and then analysed water saving potential of large-scale gravity irrigation districts in the Yellow River. |
