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。
The research progress of plankton in ballast water and its sediment to the port of entry is summarized at home and abroad. All the research results show that a large number of plankton live in ballast water and its sediment to the port, among which phytoplankton By physiological dormancy or dormancy cell survival, and zooplankton will produce dormant eggs, the presence of these dormant states have increased the risk of invasive alien organisms; at the same time elaborated at home and abroad on the sailing process of ballast water abundance changes The results show that the species composition and abundance of plankton in ballast water vary greatly between different routes. Finally, the paper expatiates on the existing problems and research prospects in this area.
