船舶压载水及其沉积物中浮游生物研究概况

Research on plankton in ballast water and sediment

概述了国内外对到港船舶压载水及其沉积物中浮游生物的研究进展,各研究结果均表明,到港船舶压载水及其沉积物中存活了大量的浮游生物,其中浮游植物可通过生理休眠或产生休眠细胞存活,而浮游动物则会产生休眠卵,这些休眠状态的存在都加大了外来生物的入侵风险;同时阐述了国内外对航行过程中压载水浮游生物丰度变化的研究现状,结果表明:不同航线的压载水中浮游生物的种类组成和丰度变化存在差异较大。最后对该研究领域存在的问题和研究前景进行了展望。

In this paper,the researches on the plankton in ballast water and sediment in the arrival ships are overviewed.The results showed that there were large number of plankton survived in the ballast water and sediment.The resting cells and physiological dormancy of phytoplankton and the rest eggs of zooplankton in the ballast water and sediment increased the risk of biological invasion.The researches on the changing of plankton abundance in ballast water during voyages were overviewed at the same time.The results showed that the species and abundance of plankton in ballast water and sediments in different routes were different.And the problem and research prospect of this field was expected.
