   摘要：目的运用多维尺度方法将山东主要港口海域及其入境船舶压舱水中的病原菌进行分析，证实入境船舶压舱水水样与本地港口海域水样两两之间在细菌组成上的异同。方法将青岛前湾港（编号B01-B04）、烟台港（编号B05-B07）和日照港（编号B08-B10）海域海水和三地港口压舱水分离出的59种（属）细菌进行非计量多维尺度分析。结果三地港口海域细菌组成没有明显不同；入境船舶压舱水中细菌组成不同于港口海水中细菌组成；压舱水中细菌组成与入境港口无关，与船舶来源地密切相关。结论三地港口海域均可能受到压舱水的外来污染。

    Abstract:   Objective   Usingmultidimensional scaling methods，to analysze pathogenic bacteria inmain Shandong port  water and entry ship ballast water, and toconfirm the difference of bacteria between the entry ship ballastwater and the local port area.   Methods   A total of 59bacterias isolated from Qingdao Harbor (No.B01-B04),Yantai Harbor(No.B05-B07), Rizhao Harbor (No.B08-B10) and three entry shipsballast water were analyzed by NMDS.  Results   Thebacterial composition in three harbor water was not significantlydifferent, the bacteria composition of ballast water in entry shipswas different from the port seawater. The bacterial composition inballast water was independent of the harbor, but closely relatedwith the origin of the ship.   Conclusion   The portwater are likely to be polluted by foreign ballast water.
