摘　　要：于2006年8月～2007年10月，分春夏秋冬四个航次对山东威海一日照近岸海域进行了现场调查，研究了该海区浮游细菌丰度、生物量及可培养异养细菌生物量的分布特征，探讨了它们与温度、溶解氧、总有机碳、总N、总P和活性磷酸盐之间的关系。结果表明：浮游细菌生物量具有一定的时间、空间分布特征，冬季浮游细菌生物量明显低于其他三个季节，近岸生物量高于远岸区域；浮游细菌丰度及生物量与温度、溶解氧、总有机碳呈非常显著相关关系（P〈0．01）；夏冬季节可培养异养细菌数与总N、总P及PO4-P均呈现显著相关关系，表明以上三种环境生态因子可能是该海域可培养异养细菌生长的限制因子。The Distribution of bacterioplankton abundance/biomass and cultivable heterotrophie bacteria in the coastal waters from Weihai to Rizhao of Shandong province was studied. The relationships between them and the environmental factors, temperature, total organic carbon, dissolved oxygen （DO）, total nitrogen, total phosphorus and active phosphate, were also analyzed. The results showed that the bacterioplankton biomass in winter is much lower than in other seasons, and the biomass in near coast is higher than in far coast. Both baeterioplankton abundance and biomass have highly significant correlations （ P 〈 0. O1 ） with temperature, total organic carbon and DO. The results showed that they could be influenced by these environmental factors. The correlation is highly significant between cultivable heterotrophic bacteria and total nitrogen,total phosphorus and active phosphate in summer and winter. The results showed that the three kinds of environmental factors might be the primary limitation factors to the distribution of cultivable heterotrophic bacteria.
