| 英文摘要 | Permafrost degradation affects soil properties and vegetation, but little is known about its consequent effects on the soil bacterial community. In this study, we analyzed the bacterial community structure of 12 permafrost-affected soil samples from four principal permafrost types, sub-stable permafrost (SSP), transition permafrost (TP), unstable permafrost (UP) and extremely unstable permafrost (EUP), to investigate the effects of vegetation characteristics and soil properties on bacterial community structure during the process of permafrost degradation. Proteobacteria, Acidobacteria, Actinobacteria and Bacteroidetes were the predominant phyla in all four permafrost soil types. The relative abundance of Proteobacteria decreased in the order SSP > TP> UP > EUP, whereas the abundance of Actinobacteria increased in the order SSP < TP < UP < EUP. Moreover, the Actinobacteria/Proteobacteria ratio increased significantly in the order SSP < TP < UP < EUP along with permafrost degradation, which may be useful as a sign of permafrost degradation. Redundancy analysis (RDA) showed that bacterial communities could be clustered by permafrost types. Analysis of single factors revealed that soil moisture (SM) was the most important factor affecting the bacterial community structure and diversity, followed by soil total nitrogen (STN) and vegetation cover (VC). Partial RDA analysis showed that the soil properties and vegetation characteristics jointly shaped the bacterial community structure. Hence, we can conclude that permafrost degradation, caused by global warming, affects vegetation and soil properties and consequently drives changes in the soil bacterial community structure. |
