| 摘 要： | 研究了 1 999年 4～ 5月渤海水体浮游细菌分布与生态环境因子的关系。结果显示 ,渤海春季表层水体浮游细菌含量与水温和溶解性有机碳呈正相关 ,相关系数分别为 0 .6 0 1 (P<0 .0 1 )和0 .4 0 6 (P<0 .0 5 ) ,并与溶解氧含量呈负相关 ,相关系数为 0 .5 1 9(P<0 .0 1 ) ;底层水体浮游细菌含量与水温、溶解性有机碳 (dissolved organic carbon,DOC)、颗粒性有机碳 (particulate organic carbon,POC)和叶绿素 a含量呈正相关 ,相关系数分别为 0 .82 0 (P<0 .0 1 ) ,0 .6 6 1 (P<0 .0 1 ) ,0 .5 31 (P<0 .0 1 )和 0 .4 42 (P<0 .0 5 ) ,并与溶解氧含量呈负相关 ,相关系数为 0 .6 5 0 (P<0 .0 1 )。表明水温和DOC、POC含量是渤海水域浮游细菌含量的主要限制因子 ,而水体中的溶解氧 (dissolved oxygen,DO)含量与浮游细菌的含量有关 |

| Abstract: | This paper presents the relationship between the environmental factors and the distribution of bacterioplankton in the Bohai Sea studied from April to May in 1999. The results show that the number of bacterioplankton in the surface layer was closely correlated with the concentration of dissolved organic carbon(DOC) and water temperature ( r =0.406, P <0.05 and r =0.601, P <0.01 respectively). The number of bacterioplankton in the bottom layer was closely correlated with the concentrations of DOC ( r =0.661, P <0.01) and particulate organic carbon (POC) ( r =0.531, P < 0.01 ), chlorophyll a ( r =0.442, P <0.05), and water temperature ( r =0.820, P < 0.01 ). The numbers of bacterioplankton in both surface and bottom layers were also correlated with dissolved oxygen. The results indicate that the main limiting factors to the number of bacterioplankton were the contents of DOC and POC, as well as the water temperature in the Bohai Sea in spring. |
