摘要
根据2006-2007年间采自福建省4个主要港口12艘外轮（包括8条集装箱船和4条散货船）的压舱水样品，研究压舱水生物的分布特点，结果表明进入该水域的外来船舶压舱水生物物种丰富度和个体丰度高，共发现浮游植物7门86属240种（包括60种赤潮生物）和浮游动物5门30属52种；经3种网目（20，77，和160μm）筛网收集的不同粒径生物的平均丰度分别为：动物38858．3ind．／m^3（粒径77～160μm）和782．3ind．／m^3（粒径〉160μm）；植物3625．0cells．／dm^3（粒径20～77μm）和134．1cells．／dm^3（粒径77～160μm）。压舱水生物的分布及生存状态与水样的盐度及水龄相关。初步评估外来压舱水生物排放对福建沿海的潜在入侵风险。
Distribution characteristics and survival state of organisms from ballast water samples collected from 12 exotic ships （including 8 container ships and 4 bulks ） entering 4 major ports of Fujian between 2006 and 2007 were studied. The results show that rich diversity and high abundance of organisms in ballast water of exotic vessels entered Fujian. A total of 240 taxa belonging 86 genera of 7 phytoplankton phyla （including 60 red tide species）, and 52 taxa （including planktonic larva） belonging 30 genera of 5 zooplankton phyla were found. The average abundance of size-fractionated organisms concentrated through a series of sieves （20, 77, and 160 m mesh） were 38858.3 and 782.3 ind. / m^3 of zooplankton （particle size of 77-160 m and 〉160 m, respectively）, and 3625.0 and 134. 1 cells/dma of phytoplankton （particle size 20-77μm and 77-160μm, respectively）. The distribution characteristics and survival state of organisms are correlated the age and salinity of ballast water. The potential invasion risk of discharge of organisms from exotic ship＇s ballast water to Fujian waters were assess roughly.
