开发利用咸水资源是解决淡水资源缺乏的一条重要途径,但不合理的开发利用可能会引起土壤盐渍化等一系列的生态环境问题。对国内外咸水灌溉的现状、土壤盐分积累及其生态环境效应、土壤盐分淋洗过程及效果、土壤盐分淋洗模型等方面对进行了综述,并对本领域需要进一步研究的问题进行了展望,以期为咸水资源的合理利用和土壤盐害的防治提供参考。
開髮利用鹹水資源是解決淡水資源缺乏的一條重要途徑,但不閤理的開髮利用可能會引起土壤鹽漬化等一繫列的生態環境問題。對國內外鹹水灌溉的現狀、土壤鹽分積纍及其生態環境效應、土壤鹽分淋洗過程及效果、土壤鹽分淋洗模型等方麵對進行瞭綜述,併對本領域需要進一步研究的問題進行瞭展望,以期為鹹水資源的閤理利用和土壤鹽害的防治提供參攷。

Development and utilization of saline water resources is one of important ways to solve the lack of fresh water resources . But irrational exploitation may cause a series of environmental problems ,such as soil salinization .In order to provide references for rational use of saline water and preventing soil salt damage ,the status of saline water irrigation ,soil salt accumulation and its ecolog‐ical effects ,soil salt leaching process and the effects ,and soil salt leaching models are reviewed ,and the problems that need further research in this field are prospected .
