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逐年发生较大变化,在现代灌区建设中,存在许多机理不清的新的问题,需要理论支撑。兹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方面总结了2000年以来河套灌区的研究成果,总结发现在未来的研究中,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。Hetao Irrigation District in Inner Mongolia is an important grain and oil production base in China.With its quota of Yellow River water falling continuously over the past decades,there have been substantial changes in land use,water and salt distribution and ecological environment in the district.Restructuring agricultural production in the region is challenging amid the reduced quota of water.Improving our understanding of the mechanisms underlying water and solute movement is hence critical.We reviewed in this paper the research results achieved over the past two decades,including spatiotemporal distribution and transport of soil water and salt,response of crops to brackish water irrigation,soil structure alteration in the saline alkali soil,soil water and salt movement induced by freezing-thawing and the autumn irrigation,and outlined the future prospect for the district.Based on previous experiences and work,we propose that future research on water and salt dynamics in the region should take its ecological security as a goal and continue to improve applications of modern technologies.
