【摘要】 随着气候不断变化和社会经济的高速发展,我国草地生态系统的盐碱化情况日益严重,草地的盐碱化不但会严重威胁当地的生态安全还会制约牧区社会经济的发展,对盐碱化草地进行修复势在必行。生物修复是一种成本低、成效显著、对环境影响小的技术,近年来在盐碱化土壤修复研究领域备受关注。综合介绍了植物修复、微生物修复、植物-微生物联合修复等3种生物修复技术领域主要开展的研究内容及应用情况进展,重点分析和探讨了植物促生菌和AM真菌在提高牧草耐盐碱胁迫和促进盐碱化草地土壤植物修复效率中的作用和潜在应用前景,旨在为盐碱化草地的修复治理奠定理论基础和提供研究思路,对盐碱化草原生态系统的恢复具有十分重要的实际意义。更多还原

【Abstract】 With the intensification of climate change and the rapid development of social economy,the salinization of grassland ecosystem in China is becoming more and more serious. The salinization of grassland will not only seriously threaten the local ecological security but also restrict the social and economic development of pastoral area. It is imperative to repair the saline-alkali grassland. Bioremediation is a low-cost,effective technology with little environmental impact,and recently it has attracted much attention in salinized soil remediation. This paper comprehensively introduces the research contents and application progress in three fields of bioremediation technology,including phytoremediation,microbial remediation,and combined plant-microbe remediation. We focuses on the analysis and discussion of the role and potential application prospects of plant probiotics and AM fungi in improving the saline-alkali stress tolerance of forage grass and promoting the phytoremediation efficiency of saline-alkali grassland soil,aiming to provide theoretical basis and research ideas for the restoration and treatment of salinized grassland,which is of great practical significance to the restoration of salinized grassland ecosystem.更多还原
