%X To investigate phytoplankton species composition and biodiversity in Dongjiang River, we sampled the river water repeatedly at 51 sampling points in January 2010. We conducted research into the features of the phytoplankton community in the river, including species composition, density, dominant species and biodiversity, and evaluated the river water quality to support the comprehensive management of Dongjiang River. We identified 83 phytoplankton species (including deformation), belonging to seven classes. Among them, Bacillariophyta and Chlorophyta were the main phytoplankton groups. There were 38 species of Bacillariophyta in the mainstream, amounting for 45.78% of the total phytoplankton species, and 53.99% of total phytoplankton cell abundance. There were 28 species of chlorophyta in the mainstream, accounting for 33.73% of total phytoplankton species, and 14.72% of total phytoplankton cell abundance. The universal dominant species in the river were Cryptomonas ovata, Melosira varians, Nitzschia sp., Cyclotella sp. and Navicula sp. Statistical results show that phytoplankton community composition and dominant species were similar with the survey in summer 2010. The cell density of phytoplankton was between 0.51×104 and 366.04×104 cells·L-1. The cell density downstream was significantly greater than mid-and up-stream. The index of biological diversity was relatively consistent in all sections of the Dongjiang River, whereas species diversity and composition upstream were more stable than mid-and down-stream. According to the evaluation of the above-mentioned phytoplankton diversity index, it seems that the water in Dongjiang River is not severely polluted.
