| 摘 要： | 2001年夏季对胶州湾异养浮游细菌在一个潮周期内的变化规律及影响因素进行了研究。结果表明,胶州湾异养浮游细菌数量的垂直分布特征是表层大于底层,表层平均8.99×109个/L,底层平均5.23×109个/L。胶州湾水体异养浮游细菌日变化幅度在表层水体较为明显,底层相对较小,但其变化规律均为最高值在小潮期而最低值出现在大潮期。浮游动物摄食、浮游植物光合作用产生的溶解有机物及水温和日光中的紫外辐射是影响胶州湾异养浮游细菌昼夜变化的主要因素,水交换是影响其日变化的主要因素。 |

| Abstract: | Characters of variation and impacting factors of the biomass of heterotrophic bacterioplankton in Jiaozhou Bay in summer were studied in 2001. The biomass was larger and showed a day-night variation in surface waters is more obvious than in bottom waters with an average of 8.99×109 cell/dm3 and 5.23×109 cell/dm3 respectively. The largest biomass occurred in low tide period and the smallest occurred both in surface and bottom waters in high tide. The main impacting factors on the day-night variation of the biomass were grazing pressure by zooplankton, the supply of DOC from phytoplankton, the temperature of water and the sunlight irradiation. Meanwhile, the dominative effectting factor of the daily variation of the biomass was the dynamic of sea water. |
| Keywords: | heterotrophic bacterioplankton characters of variation impacting factors Jiaozhou Bay |
