由于气候及人类活动因素的影响,中国西北干旱区灌区土壤盐渍化问题日趋严重,已成为近年来的研究热点。综述了西北干旱区灌区盐渍化问题的研究现状、现有的研究方法和主要研究内容,并提出了存在问题和进一步研究的思路:(1)在干旱区灌区土壤水盐运动研究中,引起灌区盐渍化的盐分来源与去向问题涉及较少,有待深入研究;(2)干旱区灌区灌溉方式存在很多问题,尤其是咸水灌溉对灌区土壤盐渍化的影响问题还需要进一步研究;(3)关于干旱区灌区盐渍化土壤改良研究,可以考虑将各种措施优化组合达到最佳改良效果,这将是今后制定盐渍土改良措施的一个方向。
Due to the influence of climate and human activities, the problem of soil salinization in the irrigation area of northwest China’s arid region has become increasingly serious and has become a research focus in recent years. This paper summarizes the research status, existing research methods and main research contents of salinization problems in irrigation area of northwest arid area in Northwest China, and puts forward some existing problems and ideas for further research. (1) In the research of soil water and salt movement in irrigation area of arid area, (2) There are many problems in the irrigation methods of irrigation area in the arid area, especially the effect of saltwater irrigation on the soil salinization in the irrigation area; ((2) 3) As for the improvement of salinized soil in irrigated area of arid area, we can consider optimizing the combination of various measures to achieve the best improvement effect. This will be one direction for the improvement of saline soil in the future.
