- Abstract
To explore the association between phytoplankton community structure and water quality of the Tianhe Reservoir in Wenzhou, Zhejiang, we examined the phytoplankton and physico-chemical factors in the Tianhe Reservoir from February 2019 to January 2020. A total of 89 phytoplankton species belonging to 60 genera and 7 phyla were identified. The annual average abundance and bio-mass of phytoplankton were 2.02x 10 5 cells • L-1 and 0.26 mg • L-1 respectively. Bacillariophyta was dominant in the whole year. Chlorophyta was dominant in spring and autumn. Cyanophyta was dominant in summer. Both Euglenophyta and Pyrrophyta appeared in the whole year. Cryplophyta appeared in autumn and winter. However, none of them was dominant due to their low abundance. The dominant species throughout the year were Melosira granulata, Synedra acus, Navicula crypto-cephala, Asterionella formosa, Pseudoanabaena, Closterlum venus, Pediastrum duplex, Peridinium bipes, Dinobryon cylindricum and Cryptorrwnas ovata. Results of redundancy analysis ( llDA) showed that water temperature, total nitrogen, CODMn and pH value were the main factors driving phyloplanklon community structure in the whole year. Acconling to the evaluation based on diversity indices, including Shannon index, Pidou evenness index, Margalef richness index and comprehensive trophic status index ( Ttl), water quality of Tianhe Reservoir is between oligotrophication and rnesotrophication.
