摘要： This study employed Illumina MiSeq high-throughput sequencing to explore the composition of the bacterial community of Chagan Lake sediments and its response to soil physicochemical properties. Our findings indicated that bacterial abundance and diversity are significantly correlated with water depth. Particularly, the bacterial alpha diversity and phyla relative abundance increased with water depth. Furthermore, the five dominant bacterial phyla in the bacterial community according to all plots were Proteobacteria, Chloroflexi, Acidobacteriota, and Actinobacteriota. Moreover, our findings indicated that electrical conductivity (EC), pH, and total carbon (TC) in sediments are important factors that affect the bacterial community structure and diversity of sediments. In summary, the bacterial community structure and diversity varied significantly in different plot sediments of Chagan Lake, which were regulated by soil nutrients and physical properties. The results of this study can be used to further explore the potential relationship between bacterial communities and the environment, and provide a scientific basis for the prediction of ecosystem structure and function of alpine inland wetlands.
