摘　　要：盐碱土资源是一种很重要的土地资源,随着人口增加与土地减少、资源短缺与生态恶化的矛盾日益尖锐化,人们越来越重视开发利用盐碱地来缓解危机,使人类的食物供应获得更为广阔的来源。据此,本文回顾与分析了国内外盐碱土改良技术的研究状况,主要包括土壤盐渍化的防治、耐盐植物的开发研究、作物耐盐机理、农艺措施改良盐碱土、化学改良碱化土等不同措施改良盐碱土的技术与进展,并对今后需进一步研究的问题进行了展望。The saline -alkali soil is a very important kind of land resource. With the population growth and the decrease of land, shortage of resources and ecological deterioration have become increasingly acute. More and more attention has been paid to the exploitation and utilization of saline- alkali soil to alleviate the crisis, and to make the human food supply obtain a broader source. In the paper, the research advances on saline -alkali soil improvement technology at home and abroad were reviewed, including the prevention of soil salinization, the exploitation of salt - tolerant plants, the mechanism of salt resistance, the agronomic and chemical measures to improve the saline - alkali soil and so on. The further research was also previewed.
