农业用水的节约和利用

Utilization and Economize on Water Resources

缺水是一个世界性的问题,中国的北方属于绝对缺水地区。从世界范围来看,农业是最大的用水户,农业用水占总淡水用量的2 /3。根据我国的自然条件和社会经济具体情况,制定地区节水灌溉规划的原则是:发展衬砌渠道输水与管道输水相结合的灌溉系统,重视改进地面灌溉方法和采用节水灌溉制度,鼓励地面水与地下水联合运用,加强工程节水技术与农业节水技术的结合,因地制宜发展先进的节水灌溉技术和传统节水灌溉方法,制定合适的节水政策。

Lack of water is a world-wide problem, and North-China belongs to the area (that) is absolutely short of water. Agriculture depletes the largest part of water, which takes up 2/3 of the overall usage of the fresh water across the world. Principles have been formulated according to natural, social and economical conditions of our country: developing the irrigation system with the unity of the water-transportation by (irrigation) canals and pipes; attaching importance to improve ground irrigation methods and water-saving irrigation systems, encouraging the joint utilization of ground water and underground water; strengthening the combination of water-saving skills in industrial engineering and agriculture and thus developing advanced water-saving irrigation methods and drawing out suitable water-saving policies according to circumstances.
