Abstract
To understand the Laoshan Reservoir's water quality, the physical and chemical indicators, phytoplankton community structure and cell density of the reservoir in 2008 were monitored. The results showed that total 62 species (7 phylum and 45 genus) phytoplankton samples were detected. The majority of them were green algae and diatom that amounted to 48.39％ and 27.4％ of total species respectively. The seasonal variation of phytoplankton community structure was significant. The diatom sat at the primary position in March, and the green algae was the most in July,August and October. The dominant species were Anabaena Bory. , Pandorina morum Bory. , Crytomonas Ehr. , and Cyclotella K()tz. The average number of phytoplankton per liter in water was 12.8 × 105 and the highest value was 40.5 × 105 appeared in August. The mass concentration of Chlorophyll a was 7.05 mg/m3. The value of synthetical nutrition state index was 50.6. The water body of the reservoir showed the tendency of transformation from mesotrophication to light eutrophication.关键词
