摘要
甘肃农业灌溉发展的主要途径包括:修建水库、塘坝,蓄余补缺;利用有利地形,自流引取河川径流;在沿黄地区建设高扬程提水工程;灌排结合,重复利用地下水资源;发展节水灌溉。在取得成绩的同时,仍然存在水资源缺乏、工程老化、田间工程不配套、水利基础设施建设水准低、节水灌溉普及率低、灌溉面积的发展方向不明确等问题。
Irrigated agriculture has been promoted in Gansu Province by means of construction of reservoirs and ponds, water diversion from rivers by gravity and water lifting in Yellow River flood plain, combination of irrigation and drainage, reuse of groundwater resources and water saving irrigation development. Although achievement has been made, problems such as lack of water resources, aging of irrigation facilities, incomplete of on-farm irrigation facilities, low standard of water infrastructures, low popularization rate of water-saving equipment etc. are existed.
