摘　　要：盐碱地是我国土地资源的重要组成部分,近年来,随着人口增长和国民经济的发展,人增地减的矛盾日益突出,盐碱地改良利用也随之成为研究的热点问题之一。因地势、气候、环境等各种原因,我国大部分地区的农业生产持续受到盐渍危害。对盐渍土采用生物措施改良,特别是种植耐盐植物,不仅能够降低盐碱地土壤的含盐量、提高土壤肥力,而且可以发展优质作物,起到改良和利用的双重作用。该文分析了盐碱地的成因及危害,讨论了耐盐植物的不同特性以及不同的盐碱条件下适宜的耐盐植被品种,并对未来盐碱地生物改良进行了展望。Saline-alkali soil is one of the important parts of land resources in China.In recent years,with the growth of population and economic development,the contradiction of increasing population and decreasing soil area is be⁃coming more and more prominent.Due to terrain,climate and other factors,most of China′s agricultural production continues to suffer from salt damage.The improvement of saline-alkali soil by biological measures,especially the planting of salt-tolerant plants,can reduce the soil salt content and increase the soil fertility.At the same time,it can be used as a high-quality crop to develop agriculture,playing a dual role of improvement and utilization.Therefore,through the analysis of the causes and hazards of saline-alkali soil,this paper discusses the different characteristics of salt-tolerant plants and the suitable salt-tolerant vegetation varieties under different saline-alkali conditions.Fi⁃nally,the future biological improvement measures are prospected.
