摘 要(英文):The role of phosphorus cycling in algal metabolism was studied in a shallow
lake, Donghu, in Wuhan using the methods of measuring cell quota C, N and
P, and calculating nutrients uptake rate by algal photosynthesis. The mean
daily phosphorus uptake rate of phytoplankton varied between 0.04-0.11 and
0.027-0.053 g/m super(2)/d in stations I and station II, respectively. The
turnover time of phosphorus in phytoplankton metabolism ranged from
0.75-5.0 days during 1979-1986. The available P was 0.176 ( plus or minus
0.156) g/m super(3) (mean plus or minus SD) in 1982 and 0.5982 and 0.491 (
plus or minus 0.24) g/m super(3) in 1986. The relationship between P/B
ratio (Y) and TP (X: mg/l) was described by the following regression
regulation Y = 1.163 + 0.512 logX (r = 0.731, P < 0.001). The dynamics of
algal biomass and algal species succession were monitored as the indicators
of environmental enrichment.
