‘壹’ 黄骅港海区情况和浮游动物种类
黄骅港一期工程疏浚物倾倒预选区的浮游生物调查
王立俊;陈伟斌;李崇德
分析了 1 995年 1 0月黄骅港一期工程疏浚物倾倒预选区浮游生物调查样品和资料。结果表明 ,调查区的浮游植物是以圆筛藻 (Coscinodiscusspp .)等为优势种的近岸广温生态群 ,浮游动物是以强壮箭虫 ( Sagittacrassa)等为优势种的近岸低盐生态群 ,且浮游生物的种类和数量都很丰富。文中还对疏浚施工提出了加强对疏浚船只倾倒到位率监督 ,根据海洋生物繁殖季节调整疏浚活动等措施 ,以最大限度地减小因疏浚施工对生态环境造成的危害。

浮游生物是海洋生物生产力的主要生产者 ,在生态系统能量流动和物质循环中起着关键作用。许多研究表明 ,某一海区浮游生物一旦受到污染损害 ,往往会破坏这一区域的海洋食物链 ,进而危及整个生态系统。因此 ,在进行大型海洋工程建设过程中 ,应尽量减少对施工海区浮游生物的危害

In this article, analysis is made of the plankton data, obtained in Oct. 1995 for the proposed dredged material mping zone of Huanhua harbor phase I project. The results show that the phytoplankton is a community which is dominantly composed of Coscinodiscuss spp. et al., the zooplankton is one dominantly composed of Sagitta crassa et al., and moreover, the plankton are rich in species and quantity. Also proposed in this article are the measures for monitoring the correct mping sites of dredgers and adjusting the dredging according to the reproctive seasons of marine organisms, so as to minimize the harm done to the ecological environment by dredging.
