在盐碱地的各项治理措施中,生物措施因其"省水、低投入、环境友好型"等优点而被认为是目前最具有潜力的改良途径,具有广泛的应用前景,但对其研究目前还仅处于初步阶段. 通过查阅大量中外相关文献资料并结合作者在该领域多年的实验研究,本文详细评述了盐碱地盐生植物改良的研究动态,分析了盐生植物改良盐碱地的机理;论述了盐生植物的分类和改良方式,系统分析了根际土壤微环境和植物生长发育及养分吸收等对生物措施改良盐碱地的响应. 系统分析发现生物改良对盐碱地改良的效果显著,潜力巨大,同时指出了目前在盐碱地生物改良研究方面存在的问题,并对其前景进行了展望,以期为盐生植物盐碱地改良的后期研究提供直接参考.

Among the measures of saline -alkali land improvement , biological method is considered to be the most effective way which has the advantages such as water -saving, low cost, friendly environmental etc and promising application prospect .But research on the aspect is only at the preliminary stage .Combi-ning reading large number of domestic and foreign relevant literature with years'experimental research in this field,this paper reviewed the research progress on halophyte improvement technology in saline -alkali land, analyzed the mechanism of improving saline -alkali soil with halophyte ,discussed the classification and improved way of halophyte ,and systemically stated the response of soil micro environment around rhi-zosphere , plants'growth and nutrient uptake on saline -alkali soil improvement with halophyte .As a re-sult, the biological method is regarded as a promising method for saline -alkali land improvement and has great potential .It proposed the problems existing in improving saline alkali soil with halophyte and look into its application prospect .The result can provide direct reference for the later study on saline alka-li soil improving by halophyte .
