Soil bacterial community diversity under different stages of degradation in zoige wetland
若尔盖高原湿地不同退化阶段的土壤细菌群落多样性

Both culture-dependent and culture-independent methods,denaturing gradient gel electropho-resis(DGGE) based on the sequence of 16S rDNA,were used to examine the microbial quantity,bacterial community structure and diversity in different soil types(Peat soil,Swamp soil,Meadow soil and Sandy soil) and soil detphs(0-20 cm,20 cm-40 cm and 40 cm-60 cm) under different stages of degradation in Zoige Wetland.Experimental results showed that total microbial quantity decreased with the soil types(Peat soil>Meadow so...
