摘　　要：根瘤菌是一种在环境中广泛存在,常与豆科植物共生结瘤固氮的细菌类群,在农、林、牧业的可持续发展中具有重要作用。近年来研究发现,除了人们熟知的固氮功能,根瘤菌还参与环境中重金属、有机物等污染土壤的修复,在生态环境修复、维持土地生产力以及节能减排方面发挥了重要的作用,尤其是根瘤菌与豆科植物联合修复污染环境效果更为显著。本文综合介绍了根瘤菌在重金属、有机物等污染土壤及滨海盐渍土壤修复中的地位、作用及潜在价值,以期为改善生态环境提供一些可参考的方法和依据。Rhizobia have traditionally been considered as legume endosymbionts and have generally been isolated from nodules on leguminous plants. More recently,Rhizobia have been found in different environments. In addition to well-known nitrogenfixing capability,Rhizobia also play a very important role in environmental modification,maintaining land productivity,energy conservation and emission reduction,especially the superiority of the Rhizobium-legume symbiosis in remediation of contaminated soils. This article reviewed recent developments of Rhizobia for promoting plant-growth and improving remediaton of contaminated soils by heavy metals,organic wastes and salinization,expecting to offer some available ways to improve the environment.
