【 摘 要 】

The purposes of this research are to analyze the water quality and measure the carbon absorbtion in water of West Sunter Lake using the phytoplankton community. The sampling and analysis of water quality and phytoplankton using the APHA method. The result show that DO is 1.1-1.4 mg/L),BOD is 10.34 to 27.35 mg/L, COD is 23-130 mg/L, and phosphate is 0.38-0.57 mg/L. The range of index values were at 0,128 to 2,516 for the Diversity Index (H'), 0.003 to 0.924 for the Evenness Index (E), that is waters this medium polluted. The study indicated that the water quality and productivity of West Sunter Lake is impacted by the activities around West Sunter Lake, especially the household activities. The value of chlorophyll-a in the Reservoir was ranging from 3.2-386.9 mg/m3or 0.89 s/d 105.52 mg C/m3and carbon which absorbed by phytoplankton are 2×109to 14×109ton/year or 9×103to 50×103ton/m3. The amount of carbon absorbtion by phytoplankton per year proves that phytoplankton have an important role in reducing CO2emissions.
