在三亚湾开展的为期一个月的研究中，我们研究了原核生物的浮游动物摄食率与病毒裂解率的时间序列变化。结果表明，原核生物的生长率（μ）高于病毒裂解率（m_v）和浮游病毒摄食率（m_g）之和，平均值为2.69±0.66d^-1，范围为1.61~3.87d^-1；病毒裂解率平均值为0.77±0.34d^-1，范围为0.31~1.21d^-1；浮游动物摄食率平均值为0.83±0.58d^-1，变化范围为0.12~1.88d^-1。原核生物的病毒裂解碳量（C_i(v)）和浮游动物摄食碳量（C_i(g)）相当，均达到~10⁶ fg·C·mL^-1。浮游病毒裂解率与浮游动物摄食率呈负相关关系，裂解百分比（P_i(v)）与摄食百分比（P_i(g)）同样也呈负相关；然而，病毒裂解碳量和浮游动物摄食碳量呈显著正相关。原核生物的病毒裂解作用和微型浮游动物摄食作用的强度在时间序列上的变化幅度较大，而总体上裂解作用和摄食作用对原核生物死亡率的贡献相当，共同组成了原核生物碳流向的两个重要途径。

During a month-long study in Sanya Bay, we examined the temporal dynamics of zooplankton grazing and viral lysis rates in prokaryotes. Findings revealed that prokaryotic growth rate (μ) surpassed the combined rates of viral lysis (m_v) and zooplankton grazing (m_g), averaging 2.69±0.66d^-1 (1.61~3.87d^-1). The viral lysis rate averaged 0.77±0.34d^-1 (0.31~1.21d^-1), while the zooplankton grazing rate averaged 0.83±0.58d^-1 (0.12~1.88d^-1). Viral lysis carbon (C_i(v)) and zooplankton grazing carbon (C_i(g)) in prokaryotes were equivalent, each approximating 10⁶ fg·C·mL^-1. Negative correlations were observed between viral lysis rate and zooplankton grazing rate, as well as between viral lysis percentage (P_i(v)) and zooplankton grazing percentage (P_i(g)). Conversely, a significant positive correlation was noted between viral lysis carbon and zooplankton grazing carbon. Viral lysis and microzooplankton grazing exhibited substantial variability over the study period, with both processes contributing equally to prokaryotic mortality, highlighting their significance in prokaryotic carbon flux.
