| 英文摘要 | Phytoplankton growth rates and mortality rates were experimentally examined at 21 stations during the 2017 spring intermonsoon (April to early May) in the northern and central South China Sea (SCS) using the dilution technique, with emphasis on a comparison between the northern and central SCS areas which had different environmental factors. There had been higher temperature but lower nutrients and chlorophyllaconcentrations in the central SCS than those in the northern SCS. The mean rates of phytoplankton growth (mu(0)) and microzooplankton grazing (m) were (0.88 +/- 0.33) d(-1)and (0.55 +/- 0.22) d(-1)in the central SCS, and both higher than those in the northern SCS with the values of mu(0)((0.81 +/- 0.16) d(-1)) andm((0.30 +/- 0.09) d(-1)), respectively. Phytoplankton growth and microzooplankton grazing rates were significantly coupled in both areas. The microzooplankton grazing impact (m/mu(0)) on phytoplankton was also higher in the central SCS (0.63 +/- 0.12) than that in the northern SCS (0.37 +/- 0.06). The microzooplankton abundance was significantly correlated with temperature in the surface. Temperature might more effectively promote the microzooplankton grazing rate than phytoplankton growth rate, which might contribute to highermandm/mu(0)in the central SCS. Compared with temperature, nutrients mainly affected the growth rate of phytoplankton. In the nutrient enrichment treatment, the phytoplankton growth rate (mu(n)) was higher than mu(0)in the central SCS, suggesting phytoplankton growth in the central SCS was nutrient limited. The ratio of mu(0)/mu(n)was significantly correlated with nutrients concentrations in the both areas, indicating the limitation of nutrients was related to the concentrations of background nutrients in the study stations. |
