宁夏河套灌区农业水资源高效利用模式研究

提出了宁夏河套灌区市场经济条件下农业水资源高效利用模式。通过对市场经济条件下灌区农业水资源高效利用机理的研究和对市场条件下农业水资源高效利用原则的剖析,认识到宁夏河套灌区要在市场经济条件下实现农业水资源高效利用,必须基于投入产出分析做好以下6方面的工作:①大型灌区骨干工程更新改造;②中低产田改造配套;③地表水与地下水联合运用;④改变作物种植结构和灌溉制度;⑤实施灌区现代管理;⑥合理调整水价。

Analyses of the mechanisms and the principles of effective utilization of agricultural water resources in Ningxia Hui Autonomous Region

This research developed a model for effective utilization of agricultural water resources under market economy in the irrigated areas of the Yellow River in Ningxia Hui Autonomous Region.Through the analyses of the mechanisms and the principles of effective utilization of agricultural water resources in the irrigated areas under market economy,it was concluded that,in order to realize the effective utilization of agricultural water resources in the irrigated areas of the Yellow River in Ningxia Hui Autonomous Region,six strategies must be implemented:(1)the renovation and modification of the key projectin the large-scale irrigated areas;(2)the lower-yield field improvement;(3)the conjunctional use of the surface water and ground water;(4)adjusting cropping pattern and irrigation schedule;(5)the modern management of irrigated areas;and (6)water price regulation.
