本文主要分析了黄淮海中部平原水资源现状 ,并对如何解决该地区当前已经暴露的水资源失衡问题进一步恶化进行了分析。提出了该区未来节水灌溉应重点开展小麦、玉米丰产灌溉模式 ;小麦、玉米有限灌溉模式 ;丰产灌溉条件下的土壤水分动态模型 ;以及有限灌溉条件下的土壤水分动态模型。提高作物的水分利用效率 ,这是一条解决水资源失衡问题的有效途径 ,它对本区农业可持续发展的功效是不言而喻的
This paper mainly analyzes the present situation of water resources in the central plain of Huang-Huai-Hai Plain and analyzes how to solve the problem of the current imbalance of water resources in this area. It is proposed that the future water-saving irrigation in this area should focus on the high-yielding wheat and maize irrigation modes; the limited irrigation modes of wheat and corn; the dynamic model of soil moisture under high-yield irrigation; and the dynamic model of soil moisture under limited irrigation. Increasing the water use efficiency of crops is an effective way to solve the problem of water resources imbalance and it is self-evident to the effect of agricultural sustainable development in this area
