宁夏引黄灌区节水技术发展及节水潜力分析

Development of Water-saving Technologies and Analysis of Water-saving Potential in the Yellow River Irrigated Area of Ningxia

深入剖析了宁夏引黄灌区目前面临的水问题;综合评述了灌区节水技术应用及其进展。在此基础上,采用情景分析法从输水系统及田间系统两方面计算了灌区农业节水潜力。宁夏引黄灌区农业节水潜力巨大,但只有加大节水投资,广泛推广各种先进节水技术才能最大限度地挖掘灌区节水潜力,从而缓解或解决灌区日益尖锐的水资源供需矛盾,为灌区社会、经济可持续发展提供保障。

The existent problem of water resources in Yellow River irrigated area of Ningxia was deeply discussed.the application and development of water-saving technologies were summarized.On the basis of above,the paper calculated the potential of agricultural water-saving by the scenario analysis method.The research found out large potential of agricultural water-saving in the Yellow River irrigated area of Ningxia,but depends on increase the investment of water-saving and wide spread the advanced water-saving technology.In this way,the increasing contradiction of water supply and water demand can be alleviated or solved.The result can provide the guarantee for social and economic sustainable development in the Yellow River irrigated area of Ningxia.
