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
摘要: 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。
Abstract:
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.
