黄河下游引黄节水型生态灌区的构建

Construction of Water-Saving Ecological Irrigation Area in the Lower Yellow River

黄河下游引黄灌区普遍存在水资源利用不充分、水资源紧缺、供水保证率低、泥沙淤积、非点源污染和生态系统不稳定等生态环境问题,分析了灌区的生态与环境、灌区工程、灌水技术、生态系统、灌区管理及文化现状的现状,分析了节水型生态灌区的特点、构建原则、体系构建、技术体系、评价指标,分析了通过工程措施、田间节水、管理技术和生态化建设,紧紧把握灌区实际需求,构建引黄节水型生态灌区。

The Yellow River Irrigation District in the lower Yellow River generally has ecological problems such as insufficient water resources utilization,water shortage,low water supply guarantee rate,sediment deposition,non-point source pollution and ecosystem instability.The ecology and envi-ronment of the irrigation area are analyzed.The status quo of irrigation district engineering,irri-gation technology,ecosystem,irrigation district management and cultural status,analysis of the characteristics,construction principles,system construction,technical system and evaluation in-dicators of water-saving ecological irrigation districts,analysis of engineering measures,field water conservation,management Technical and ecological construction,firmly grasp the actual needs of irrigation districts,and build a water-saving ecological irrigation area.
