于2006年8月~2007年10月,分春夏秋冬四个航次对山东威海-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。
From August 2006 to October 2007, a field survey was conducted on the coastal areas of Weihai-Rizhao, Shandong Province in four seasons of spring, summer, autumn and winter. The abundances of phytoplankton, biomass and biomass of culturable heterotrophic bacteria The relationship between them and temperature, dissolved oxygen, total organic carbon, total nitrogen, total phosphorus and active phosphate were discussed. The results showed that the biomass of planktonic bacteria had some time and space distribution characteristics. The biomass of planktonic bacteria in winter was significantly lower than that in the other three seasons, and the biomass of near-shore was higher than that of far-shore. The abundances of phytoplankton, biomass and temperature, Oxygen and total organic carbon (P <0.01). The number of heterotrophic bacteria cultured in summer and winter showed a significant correlation with total N, total P and PO4-P, indicating that the above three environmental ecological factors may be The sea area can be a limiting factor for the growth of heterotrophic bacteria.
