摘要

In order to study the effect of reed and cattail on the bacterial community structure of surface sediments of wetland in winter, high-throughput sequencing technology was used to analyze the bacterial composition. The results showed that 134 228 high-quality gene sequences were obtained by high-throughput sequencing in sediments of natural wetland in winter, and there were 13 866 OTUs, in which the number of OUT in sediments of reed wetland and cattail wetland was 6 677 and 7 189 respectively. The richness and diversity of bacterial communities in sediments of cattail wetland in winter were higher than those in sediments of reed wetland. Relative abundance of Proteobacteria in sediments of reed wetland and cattail wetland was 0.54 and 0.52, respectively. The dominant classes of bacteria were Betaproteobacteria, Deltaproteobacteria, Gammaproteobacteria and Epsilonproteobacteria, which belonged to gram-negative bacteria, indicating that the rhizosphere of wetland was easier to enrich gram-negative bacteria. Under the genus level, the dominant bacteria in the sediments were not obvious.
