| 摘 要： | 选取9艘停泊于洋山深水港、在太平洋公海海域进行压载水交换的到港船舶,分析其压载水中浮游植物的种类组成和丰度,共检测出浮游植物4门18属29种(包括变种或变型),其中硅藻门占主要优势地位,共计13属21种,占总种类数72.4%,包括未定种8种;甲藻门3属6种,占总种类数20.7%,其中未定种1种;绿藻门1属1种,占总种类数3.5%,其中未定种1种;蓝藻门1属1种,占总种类数3.5%。所有船舶压载水样品中均发现有赤潮藻,存在潜在外来种入侵风险。在公海海域进行压载水交换后浮游植物丰度远小于在国内沿岸海域交换压载水的丰度,显示公海换水可有效降低压载水内浮游植物的密度,但仍有适应港口环境的种类存在,未能完全消除外来藻类入侵的潜在生态风险。

| Abstract: | Analysis of abundance and biodiversity of phytoplankton in ballast water which was exchanged in the high seas of the Pacific Ocean for the vessels calling for Yangshan Deepwater Port was conducted to research the risk of phytoplankton invasion. A total of 4 phyla, 18 genera and 29 species (including variants) of phytoplankton were detected in the samples, in which Bacillariophyta dominates the sample results, 72.4% for Bacillariophyta (common with 13 genera and 21 species), 20.7% for Dinoflagellate (common with 3 genera and 6 species), 3.5% for Chlorophyta (common with 1 genus and 1 species) and 3.5% for Cyanophyta (common with 1 genus and 1 species). In all of the 9 ballast water samples surveyed, red tide algae were identified and there was a potential risk of invasive alien species. The abundance of phytoplankton after ballast water exchange in the high seas was much less than that of ballast water exchange in the domestic coastal waters in China. The current ballast water exchange method can reduce the risk of marine organisms invasion while the ballast water treatment system is required to eliminate hidden risks. |
