Abstract: Community structure of phytoplankton was surveyed at 8 sampling sites in ecological floating island, artificial fish nest area, and littoral restoration zone in demonstration area for ecological restoration in Xidayang Reservoir in October 2018 and May 2019 in order to understand the changes in phytoplankton species, abundance and biomass in the demonstration area in Xidayang Reservoir in spring and autumn. A total of 93 species of phytoplankton (including uncertain species), and 53 genera in 7 phyla were observed in autumn, with biomass of 30.34 mg/L and density of 4745.39×104 cells/L. Totally, 82 species of phytoplankton (including uncertain species), 52 genera in 8 phyla were found in spring, with biomass of 1.19 mg/L and density of 367.52×104 cells/L. There was significant dominant species succession both in spring and autumn, with the similarity of only 11.7%. The Shannon-Wiener diversity index (H′) was shown to be 3.87 in spring and 4.19 in autumn, showing a typical community structure dominated by members in Cyanophyta-Chlorophyta. The Pearson correlation analysis revealed that the phytoplankton density and biomass were very significantly positively correlated with temperature (T), and levels of Chl-a, CODMn, SD, and pH(P<0.05) in spring and autumn. The findings indicated that the phytoplankton diversity and community structure were in good performance in the Xidayang Reservoir demonstration area, and the restoration project had a positive effect on the phytoplankton community structure in the Xidayang Reservoir demonstration area.
