Abstract

To understand the community structure of phytoplankton in the reservoirs in Hainan Province, five typical reservoirs were sampled in December of 2006, May of 2007, August of 2011 and December of 2011. One hundred and fifty eight taxa of phytoplankton were identified and most of them belonged to Bacillariophyta, Cyanobacteria and Chlorophyta. Twenty six phytoplankton functional groups were classed and the dominant functional groups were C, J, F, P, K, Lo and S1. The main representative species were Bacillariophyta for functional groups C and P, Cyanobacteria for K and S1, Chlorophyta for J and F, and flagellate for Lo. The function groups P, S1 and F adapted well to mixing water; K, J and C frequently occurred in mesotrophic water bodies; Lo distributed mainly in the deep and large water such as Songtao, Shilu and Wanning reservoirs. Structure of phytoplankton functional groups showed seasonal difference. The dominant functional groups were C, P and S1 in the dry season. The Q index indicated that Chitian Reservoir and Songtao Reservoir were oligtrophic in the flooding season and mesotropic in the dry season. Shilu Reservoir was mesotrophic water. While Yongzhuang Reservoir and Wanning Reservoir were eutrophic in the flooding season and mesotrophic in the dry season.
