摘要：

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。笔者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。

Abstract:

Due to the influence of climate and human activities, the soil salinization problem in arid irrigated area of northwestern China has become more serious and has been the hot research topic in recent years. The author reviewed the status of soil salinization in northwest arid irrigated area and summarized the existing research methods and content. At last, the author put forward the existing problems and some ideas for future research: (1) in the study of salt and water movement in arid irrigated area, the salinity source had not been conformed and further research was needed; (2) the irrigation methods in arid irrigated area faced a number of difficult problems, especially the influence of salt-water irrigation to salinization, which were need further research; (3) in the study of soil salinization control, people can use a combination of many techniques together to gains that achieve an optimum method.
