| 英文摘要 | Purpose Baiyangdian Lake is located in the core of Xiongan New Area and is the largest freshwater lake in the North China Plain with a variety of habitats. Microorganisms are important drivers of material cycle and energy transport in freshwater ecosystems. To understand the biogeochemical circulations in Baiyangdian Lake, the bacterial community structures and influencing factors of surface sediments among the different habitats were investigated. Materials and methods Samples were taken from five areas of Baiyangdian Lake. The concentration of nutrient elements and bacterial community structures was measured. Results and discussion The bacterial community structures of different habitats were different and were influenced by the nutrients in surface sediment. Open water areas had the richest abundance of ecological functions, such as phototrophy, sulfur oxidation, sulfite respiration, nitrification, and nitrite respiration. The bacterial community structures among the different habitats were decided by different elements in sediment; sulfur was the key influencing factor of the bacterial community structure in open water; C/N ratio was the key influencing factor of reed marshes; nitrogen and organic carbon were the key influencing factors of river estuary habitat. Conclusions The bacterial community structures and ecological functions of surface sediments among habitats were different, and the dominant bacteria played an important role in biogeochemical circulations, especially in the carbon and sulfur cycles of Baiyangdian Lake. |
