| 摘 要： | 利用Biolog EcoplateTM技术通过对荒漠草原生态系统中沙米、白沙蒿、柠条、沙冬青和人工乔木林5种植被类型土壤微生物群落功能多样性分析,以探讨不同植被类型对土壤微生物群落代谢功能多样性的影响.结果表明,5种植被类型土壤微生物群落代谢活性有显著的差异(P＜0.01),5种植被类型土壤微生物群落利用碳源的种类也存在差异,氨基酸类、羧酸类和糖类是其主要的碳源利用类型.在Biolog ECO板培养基接种培养96 h后,5种植被类型土壤微生物群落多样性显示,物种丰富度指数(R)和均匀度指数(EH)差异显著,Shannon 指数(H′)差异不显著. |

| Abstract: | By adoption of Biolog EcoplateTM system,the analysis of soil microbial community functional diversity was made under 5 kinds of vegetation of Agriphyllum squarrosum,Artemisia sphaerocephala krasch,Caragana korshinskii,Ammopiptanthus mongolicus,and artificial arbor mixed stands of Pinaceae sylvestris L.& Robinia pseudoacacia L.in the desert grassland ecological system so as to probe into the effects of vegetation type on soil microbial community functional diversity.The results showed that the soil microbial... |
