摘　　要：基于相关研究文献,系统地整理和总结了近些年来膜下滴灌棉田水盐运移研究的主要内容及其最新研究进展。从短期来看,膜下滴灌可以淋洗浅层土壤盐分,保证棉花正常生长;但是,从长远来看,由于膜下滴灌灌溉定额较小,无法将盐分从根区土体中排出,棉田始终处于积盐状态,土壤盐碱化程度不断增加。在探讨膜下滴灌棉田水盐运移特征和规律的基础上,探索性地提出了今后可能需要关注的研究方向和内容。According to some relevant published literatures, advances of soil water and salt transport in cot- ton filed drip-irrigated under film in Xinjiang were reviewed and summarized systematically. In a short term, soil salts near soil surface could be transferred into deeper soil layers by drip irrigation under film, which was beneficial for cotton growth. However, salts would be accumulated in root zone and soil salin- ization would arise in a long term, because the quota for drip irrigation under film was usually small. Based on the discussion of the characteristics and laws of soil water and salt transport in cotton filed drip-irrigated under film, some research directions and contents were suggested.
