To determine which factors may have an impact on the community composition of bacterioplankton, 15surface water samples were collected from the main cancel of the Mid-line Project of South-to-North Water Division in 5sections of Henan province, in July 2016, and 7essential environmental factors were evaluated. The results showed that water quality in the main cancel was strongly influenced by total nitrogen (TN) and the permanganate index (CODMn). Water system in Qushou, Fangcheng, and Xinzheng sections was under the mesotrophic state, and in Wenxian and Anyang sections, under the light eutrophic state. High-throughput sequencing was used to analyze distribution characteristics of the community structure, diversity of bacterioplankton. Phylogenetic analysis based on 16S ribosomal DNA sequences revealed that bacterioplankton could be subdivided into 25major phylogenetic and 407genus groups. The dominant phylogenetic groups included Actinobacteria, Proteobacteria, Planctomycetes, Bacteroidetes, Cyanobacteria, Verrucomicrobia, and Armatimonadetes. Diversity of the bacterioplankton community in the main cancel of the Mid-line Project of South-to-North Water Division could be ranked in the following order: Wenxian > Xinzheng > Fangcheng > Qushou > Anyang. The results of canonical correspondence analysis (CCA) of the relation between the bacterioplankton and 7 environmental factors showed that TN, ammonia nitrogen (NH4+-N), chlorophyll a (Chl a), chemical oxygen demand (COD), and the CODMn were the main environmental factors affecting the distribution characteristics of the bacterioplankton community.
