摘　　要：在国内外学者研究基础上,从土壤质地、管理措施、水质条件及植被条件等膜下滴灌土壤水盐运移的影响因素和土壤水盐运移研究方法进展二大方面,概括了土壤水盐运移的研究现状。并进一步探讨了膜下滴灌水盐运移研究存在的不足,如水盐调控尺度不够大,土壤中"水-根-盐"耦合问题亟待解决,缺乏长久监测土壤水盐动态变化网络以及对模型的适用性的研究还有待提高。Based on the research at home and abroad, influencing factors were texture, field measures, water quality and vegetation condition, and research transfer under mulched drip irrigation. Further, some problems about soil water summarized, such as soil method of water and salt and salt transfer were dis- cussed, for example, the regulation scale of water and salt should be expanded, the coupling problems of ＂soil-salt-root＂ hadn＇t been solved, monitoring network was deficient and the applicability of the model should be improved.
