| Abstract: |
| 【Objective】To explore the diversity of bacterial communities in Baotou Nanhai Lake of cold-arid area in ice period,【Method】the surficial sedimentary bacterial of 12 sampling sites in different areas was sequenced using high-throughput sequencing approach and then correlation thermogram analysis was performed.【Result】The result showed that the diversity of species in different areas was quite different. At the phyla level, Proteobacteria, Chloroflexi, Cyanobacteria, Bacteroidetes and Actinobacteria were dominant. The number of Proteobacteria and Chloroflexi were more than others in the sediment, Cyanobacteria (29%) and Actinobacteria (33%) were dominant in the water. The abundance of bacteria was higher in the tourism development zone. Thiobacillus, norank-f- Cyanobacteriaanaerolineaceae, unclassified-p-Chloroflexi were dominant bacteria at the genus level. Thiobacillus (21%) was higher in the sediment and norank-f- Cyanobacteriaanaerolineaceae (24%)was higher in the water, which were widely distributed in the four regions. The redundancy analysis for the relationship between bacterial communities and environmental factors revealed that the TN、DO and T had great influence on the structure of bacterial community in the water, TN、NH4+-N and COD were the same influence in the sediment, Controlling the content of these elements is an important condition for controlling the outbreak of bloom in Nanhai Lake.【Conclusion】The eutrophication of Nanhai Lake increased during the ice period, and Thiobacillus that was found in the sediments of all regions played an important role in biogeochemical cycles of sediments in Nanhai Lake. It is of great importance for preventing the occurrence of black and odorous water. |
