摘　　要：根据多年来国内外学者的研究成果,从地形地貌、气候环境及人为因素等方面探讨了河套灌区土壤盐渍化的成因,简述了盐渍化的危害及土壤盐分变化规律,并从工程措施、农业措施、生物措施、化学措施4个方面提出盐渍化的防治方法,为防治河套灌区盐渍化、提高土地利用率、改善生态环境提供参考。Salinization is strategic issues of sustainable agricultural development and ecological environment construction in arid and semi-arid areas. According to research on soil salinization by domestic and overseas scholars for many years, this paper from the topography, climate, human factors and other aspects discussed the formation cause of soil salinization in Hetao irrigation area. It briefly introduced hazard characterization of salinization and the variations of soil salinity, and put forward engineering, agricultural, biological and chemical control methods to control soil salinization, increase land utilization rate and improve the ecological environment in Hetao irrigation area.
