Preliminary Study of the Phytoplankton and Eutrophication Assessment in Wangkuai Reservoir


Abstract:
The phytoplankton community and dominant species were investigated at Wangkuai Reservoir in August and September 2010.The results showed that there were 25 species belonging to 6 phylum of phytoplankton in Wangkuai Reservoir.Cholorophyta and Bacillariophyta were major phylum in the phytoplankton community,with 9 genera (36%) and 7 genera (28%) respectively.Investigations in September 2010 found out:the algal density was 2.99×106 Cell/L;Cyanophyta and Chlorophyta accounted for up to 86.66% of total cell density;Cyclotella sp.and Leptolyngbya valderiana were dominant speciesaccounting for 61.69% of total cell density;The concentration of chlorophyll was 3.88 μg /L.The study indicated that the nutritional status of Wangkuai Reservoir was oligotrophic to mesotrophic and the water quality was good.

Key words:Wangkuai Reservoir,phytoplankton,algae community,species diversity
