| 摘要: |
| 内蒙古河套灌区是我国重要的农业规模化生产和商品粮、油基地，灌区引水量逐年减少，种植结构、土壤水盐分布规律和生态环境都发生较大变化，在现代灌区建设中，有许多新的问题机理不清，需要理论支撑。此文从区域土壤水盐时空分布特征、土壤水盐运移规律、微咸水灌溉农田-作物效应研究、盐碱地改良与土壤结构改善、冻融条件下土壤水盐运移与秋浇制度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土壤水盐运移研究和基于多种方法对盐碱地改良的研究。 |

| Abstract: |
| Hetao Irrigation Area is an important agricultural large-scale production, commodity grain and oil base in China. The amount of water diverted from Yellow River to the irrigation area is decreasing year by year and the planting structure, water and salt distribution and ecological environment 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 spatial and temporal distribution characteristics of soil water and salt, soil water and salt transport, the research of farmland crop effect under brackish water irrigation, the improvement of saline alkali land and soil structure, the study of soil water and salt transport during the freeze-thaw condition and autumn irrigation system. Based on the ecological security of irrigation area, we should pay attention to the research of soil water and salt transport, saline alkali land improvement based on various methods and the application of modern technology in the future. |
