| 摘要: |
| 水资源短缺、土壤盐渍化及肥料利用率低是制约内蒙古河套灌区农业可持续发展的三大主要因素。随着灌区节水工程的实施和黄河水利委员会对灌区引水量的限制，引黄水量大幅度减少，河套灌区的水资源合理配置、灌溉方式、水肥运筹模式及灌区生态环境发生较大变化。灌区受水资源限制和水肥管理的需要的现代灌区建设中面临许多新的问题，迫切需要理论支撑。此文从河套灌区农业耗水研究、高效节水灌溉理论、节水控盐灌溉制度和节水对作物品质影响、盐渍化灌区水氮耦合与有机无机肥耦合机制等几个方面总结了河套灌区近20年的研究成果，并提出了在未来的研究中，应加强基于灌区生态安全的高效节水灌溉技术的应用，优化灌溉制度及作物品质提升的研究、土壤碳氮循环和氮素矿化研究及现代化技术的应用。 |

| Abstract: |
| The shortage of water resources, the salinization of soil and the low utilization of fertilizer are three main factors that restrict the sustainable development of agriculture in Hetao irrigation district, Inner Mongolia. With the implementation of water-saving projects and the water restriction of the Yellow River Convervancy Commission, the amount of water diverted from the Yellow River has been greatly reduced. The allocation of water resources, irrigation methed, water and fertilizer operation and the ecological environment of the irrigation district have changed greatly. In the construction of the modern irrigation area, there were many new problems, which were needed theoretical support to explore their mechanism. In this paper, research results were summarized in the recent 20 years, including: the research of agricultural water consumption, the theory of efficient water-saving irrigation, the irrigation system of water-saving and salt control, the effect of water-saving on crop quality, the coupling mechanism of water and nitrogen, the coupling mechanism organic and inorganic fertilizer in salinized irrigation area. Based on the ecological security of irrigation area, we should pay attention to efficient water-saving, irrigation system, the crops quality, soil carbon and nitrogen cycle, nitrogen mineralization and the application of modern technology in the future. |
