| 摘 要： | 在三亚海域设置3个站位, 分别于各站位连续采集12个月表层水样。利用流式细胞仪进行浮游病毒及浮游细菌丰度的测定, 并对两者及其与环境因子之间的相关性进行研究, 同时对不同站位之间进行差异性分析。结果表明, 调查海域浮游病毒丰度(平均7.63×106viruses·mL-1)高于浮游细菌丰度(平均1.52×106cells·mL-1)。浮游病毒及浮游细菌丰度在三亚河口最高, 且有明显的季节变化, 冬春季高于夏秋季, 并且其与鹿回头半岛西侧、小东海之间均有极显著差异(P<0.01), 不同类群病毒代表的宿主类群也有所不同。调查海域总体水平浮游病毒丰度与浮游细菌丰度显著正相关(r=0.800, P<0.01); 叶绿素(Chl a)和氮盐(NO- 2、NO- 2+NO- 3、NH+ 4)是影响两者的关键因子。

| Abstract: | Surface water samples were collected monthly for a total of 12 months from three stations in Sanya. Their virioplankton and bacterioplankton abundances were measured by flow cytometry and their correlationships with evnironmental factors were also studied. The results show that the abundance of virioplankton (7.63×106 viruses·mL-1 on average) was higher than bacterioplankton abundance (1.52×106 cells·mL-1 on average). Virioplankton and bacterioplankton abundances in the Estuary of Sanya River were significantly different from those on the west side of the Luhuitou Peninsula and Xiaodonghai. The highest virioplankton and bacterioplankton abundances appeared in the Estuary of Sanya River, with obvious seasonal variation(P<0.01). The abundances of virioplankton and bacterioplankton were significantly positively correlated (r = 0.800, P<0.01); and chlorophyll a, N nutrients (NO- 2, NO- 2+NO- 3, NH+ 4) are their key ecological factors (P < 0.01). |
