我国水资源利用现状与节水灌溉发展对策

在分析我国水资源和农业用水现状的基础上,探讨农田灌溉节水途径与技术措施,提出根据经济现状,提高水的利用率和利用效率,发展节水灌溉应重点普及输水节水技术,加强地面灌水技术和节水灌溉制度的研究与推广,适度发展喷、微灌技术,并注重各项节水技术措施的综合集成,实现农田灌溉各个环节上的全方位节水

Present Situation of Water Resources Usage and Developing Countermeasures of Water -Saving Irrigation in China

Based on the analyses of the status quo of water resources and agricultural water use in China, the avenues to save water and the technical measures of farmland irrigation were explored. In view of the economic status of China, the development of water saving irrigation should lay the emphases on spreading water saving techniques of transporting water, reinforce the research and extension of surface irrigation techniques and water saving irrigation schedules, and develop sprinkler and micro irrigation techniques moderately. And also, in order to increase water use ratio and efficiency maximally, emphasis should be laid on integration of various water saving technical measures to realize water saving in all round way of farmland irrigation.
