象山港水域浮游植物与赤潮生物种群动态研究

Study on the Phytoplankton and HAB in Xiangshan Bay

本文根据 2002年 — 月对象山港进行生态调查的资料,报道了象山港水域目前浮游植物的种类 6 7组成 ( 4个门25属 种 和分布特征及赤潮生物的分布现状,并与 43 ) 1988 年同期资料进行比较,认为象山港浮游植物数量在增加,赤潮发生的时间和赤潮种类也发生了一定程度的变化 象山港赤潮多发生在春末 (夏初;赤潮生物的变化:硅藻类—甲藻类—原生动物 。 )

Based on the data obtained from the investigation in the Xiangshan Bay in 2002, the paper reported the species composition of phytoplankton ( 4 phylum 25 genus 43 species ) and the character of distribution as well as the distribution of HAB. Comparing the data with the result of 1988, it is found that the phytoplanktonic species has reduced and the quantity of phytoplankton has increased. Furthermore, the time and variety of red tides has changed too.
