摘　　要：甘肃秦王川灌区水资源紧缺,兰州新区城镇化建设加速水资源消耗趋势,使灌区水资源供需矛盾日渐突出,农业节水势在必行。根据中国西北干旱地区农业节水取得的成效和灌区农业生产节水试验,提出适宜于秦王川灌区农业节水的5条具体途径:①发展以地面灌溉为主的先进灌溉技术;②渠道衬砌;③农业节水技术与地膜覆盖栽培技术相结合;④推行膜下滴灌技术;⑤倡导节水文化,共建节水型社会。通过这些农业节水技术的实施,使秦王川灌区从简单的农业灌溉,转变为农业、城乡生活、生态、工业等多元用水格局,促进灌区经济可持续发展。Water resources are deficient in Qiuwangchuan Irrigation Area of Gansu Province,China.Urbanization construction of Lanzhou new district aggravates water resource deficiency and conflict between supply and demand of water resources.So,agricultural water saving must be enforced in this area.Based on water saving irrigation experiments in Qiwangchuan Irrigation Area and in other areas of northwest China,the authors summarizes five approaches suitable for agricultural water saving in Qiwangchuan Irrigation Area：（1） to develop advanced surface-irrigation-dominated water saving technology;（2） to apply channel lining technique;（3） to combine agricultural water saving and plastic film cultivation technologies;（4） to popularize under-film drip irrigation technology;（5） to propose water saving ideas and construct water-saving society.Integrated implementation of these measures will guarantee the water using pattern transformation from single agricultural irrigation to multiple uses,and further to promote economic sustainable development of Qiwangchuan Irrigation Area.
