摘　　要：【目的】研究新疆塔里木河上游不同生境细菌群落结构及多样性。【方法】采用免培养和可培养方法,研究塔里木河上游流域原始生境与人工开发后生境细菌群落结构及多样性差异,同时对分离的1株潜在新种进行多相分类鉴定。【结果】原始生境与人工开发后生境细菌群落结构组成差异明显,人工开发后生境细菌α多样性低于原始生境,不同生境细菌β多样性差异较大。变形菌门和放线菌门为优势菌群,并获1株链霉菌属潜在新物种。【结论】塔里木河上游不同生境样品中含有丰富的微生物资源,其细菌群落组成受人为活动的影响较大。【Objective】Analysis of the bacterial communities structure and diversty of the Tarim River in different habitats.【Methods】The culture-free and cultivable methods were used in this study to explore the bacterial community structure and diversity of Tarim River,and also identified a potential new species by using the polyphasic taxonomy method.【Results】There were significantly difference of bacterial community between the original habitat and the artificially developed habitat.There was lower alpha diversity of the artificially developed habitat than the original habitat,and it had multiple difference of the beta diversity among the different habits.Based on the cultivable methods,the Proteobacteria and Actinomycota were dominant bacterial groups in these habitats.According to the polyphasic taxonomy method,a potential new species was identified.【Conclusion】There are multiple microbial resources in different habitats of the Tarim River.The bacterial community structure has been affected by human activities.
