摘　　要：采用总活异养菌 ２２１６Ｅ平板计数法（ＨＰＣ， Ｈｅｔｅｒｏｔｒｏｐｈｉｃ Ｂａｃｔｅｒｉａｌ ２２１６ＥＰｌａｔｅ Ｃｏｕｎｔ），弧菌ＴＣＢＳ平板计数法（ＶＰＣ，Ｖｉｂｒｉｏ ＴＣＢＳ 　Ｐｌａｔｅ Ｃｏｕｎｔ），对山东荣成湾月湖水体中的细菌生物量分布进行了研究。并用多管发酵法对水体中的大肠菌群进行了检测。结果显示，大肠菌群ＭＰＮ值最高为９个／１ ００ｍｌ，低于我国海水水质标准（≤１００００个／Ｌ）。水样中的异养菌数为４．９５ × １０^(４－)３．９５×１０~５ｃｆｕ／ｍｌ，弧菌数为３．０×１０(２－)９．６ｘ １０~３ｃｆｕ／ｍｌ。泥样中的异养菌数为 １． ５ ｘ １０(４－)３． ２ ｘ １０~５ｃｆｕ／ｍｌ，弧菌数为 １０ ｘ １０(３－)２．２ｘ １０~４ｃｆｕ／ｍｌ，与之相邻的荣成湾的菌量分别为 ＨＰＣ ６．６５ ｘ １０~４ｃｆｕ／ｍｌ， ＶＰＣ ２． ３７ ｘ１０ ~３ ｃｆｕ／ｍｌ，两个海区的细菌生物量差别不大，但同现有外海水的细菌生物量资料比较，结果明显偏高，总异养菌数高出二个数量级，弧菌数高出一个数量级。The Yuehu (Moon Lake) is a lagoon-inlet system located in the Rongcheng Bay, Shandong Province, China, with an area of - 5 km^2. Development has been undergoing for aquaculture and tourism. In summer of 1999, a bacterial ecological study was carried out. By using HPC (Heterotrophic Bacterial 2216E Plate Count) and TCBS (Vibrio TCBS Plate Count ) methods, the distribution of bacteria in sediments and seawaters were also studied. We also measured conform group in seawater. The results show that the maximum of conform group MPN value is 90/L, lower than the Class I specified by the Chinese National Standard of Seawater Quality (<=10,000/L). The heterotrophic bacteria in seawater is 4.95 × 10~4-3.95 × 10~5 cfu/ml, and vibrio in seawater is 3.0 × 10~2 ---9.6 × 10~3 cuf/ml. In the sediments heterotrophic bacteria is 1 .5×10~4---3.2×10~5 cfu/ml, while vibro is in the range of 1 .0×10~3- 2.2×10~4 cfu/ml. In the Rongcheng Bay, outside the lagoon, HPC and VPC are 6.65 × 10~4 cfu/ml and 2.37× 10~3 cfu/ml, respectively Though the difference between the inside and outside the lagoon areas is not big, these values are all much higher than those in the outer seas reported in the literautre.
