摘　　要：灌溉水资源的短缺已成为干旱半干旱地区农业持续发展的一个重要限制因素,咸水资源的开发利用可有效的解决灌溉水源短缺的问题。从咸水灌溉对作物、生态环境的影响、咸水灌溉技术以及咸水灌溉条件下的改良等方面总结了国内外咸水资源灌溉利用的研究进展,为合理的利用咸水资源进行灌溉提供指导。从咸水资源灌溉利用现状来看,膜下滴灌为干旱半干旱地区有效的利用咸水和微咸水资源以及盐碱地的开发利用提供了有效的手段。但利用膜下滴灌方式进行咸水灌溉,目前仍存在一些问题,需要进一步研究。此外,如何从流域或区域尺度上评价咸水灌溉的影响,并从更大尺度维持盐分平衡及环境的可持续发展值得深入研究。The shortage of water resources used in irrigation has been a important restraint factor in arid and semiarid areas. The utilization of saline water is a effective way of easing up the problem of water resources shortage. Amount of researches have been conducted worldwide. Relevant researches and development were summarized, including the effect to crop and ecological environment, the technology of irrigation with saline water and improving measures. Drip irrigation under mulch film is an effective way for utilization of saline water and salinized land in arid and semiarid areas. But researches on irrigation with saline water through the way of drip irrigation under mulch film were scarcity. It is necessary to farther ahead with the research. In addition, for sustainable agricultural production, just like the water balance, the salinity balance also has to be maintained at the irrigation system and basin levels.
