Abstract：In order to investigate the influence on water quality and microbial diversity in intensive fish pond by Ipomoea aquatica floating-bed, and the composition and diversity of microbial communities in the samples were researched based on high throughput sequencing of 16S rRNA gene. The results revealed that the dominant bacteria were phyla Proteobacteria, Cyanobacteria, Bacteroidetes, Actinobacteria, Chloroflexi and Firmicutes, the dominant bacteria were genera Synechococcus,hgcI_clade, CL500-29_marine_group, Bacillus and Mycobacterium in the Aquaponics System, and the most dominant bacteria of rhizosphere microorganisms were phyla Proteobacteria and Cyanobacteria, the dominant bacteria were genera Rhodobacter, Hydrogenophaga and Synechococcus. Moreover, the results also showed that low coverage (3.5%) of Ipomoea aquatica floating-bed increased the dissolved oxygen content and reduced the concentration of nitrogen compounds, and improved micro-ecological balance and increased the content of the beneficial bacteria and nitrogen cycle bacteria in aquaculture water body.
