Preliminary Study of the Phytoplankton and Eutrophication Assessment in Wangkuai Reservoir

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
