摘　　要：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。In this article, analysis is made of the plankton data, obtained in Oct. 1995 for the proposed dredged material dumping 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 dumping sites of dredgers and adjusting the dredging according to the reproductive seasons of marine organisms, so as to minimize the harm done to the ecological environment by dredging.
