China irrigation amount summarized theagricultural big country is very large, we must have a systematic and feasible approach to solve the problem and research are concerned about the people,points out the present irrigation technology is not particularly good, need to plan and better way to change our living environment. You see, the scarcity of water resources has seriously restricted the development of industry and agricultureirrigation, increase water use efficiency, saving water has e an urgent need to the development of irrigation. Study on the demand according to the practical situation and the present situation of water resources in irrigation area,and puts forward several water-saving practical and effective technical solutionsand measures. Keywords : water saving technique of canal seepage control pipeline sprinkler irrigation technology 摘要: 本文归纳了新疆灌区节水的技术以及可行性的研究及数据。概括了农业大国的中国灌溉量非常的大, 我们要有一个系统并且可行的办法来解决这个人民都关心的问题及研究成果,指出了现在的灌溉技术并不是特别完善, 需要更完善的方案及方法来改变我们的生存环境。大家都看到了, 水资源匮乏已严重制约了灌区工农业生产的发展, 提高水的有效利用率, 实施节约用水成为灌区发展的迫切需要。研究需求提出针对灌区实际情况和水资源现状, 提出了几种切实有效的节水技术方案和措施。关键词: 节水技术渠道防渗管道输水喷灌技术 2003 年全疆降水总量 2982 亿立方米,地表水资源量 亿立方米,平原区地下水资源量 354
