Diatom Biodiversity, Population Distribution and Community Succession in Main HAB Area of East China Sea

Abstract

长江口附近海域是我国重要的渔业和养殖基地,同时也是赤潮高发区。硅藻是海洋浮游植物的重要组成类群,同时也是赤潮生物的重要类群。本论文通过对东海赤潮高发区硅藻的生物多样性、种群分布特征和群落演替动态等的研究,为分析东海赤潮成因和赤潮监测等提供基础数据和科学依据。本文于2002年5月-2003年5月,在东海赤潮高发区(范围在122°-123.5°E,29°-32°N)通过五个航次的调查(2002年5月、8月、11月和2003年2月、5月),研究了该海区硅藻的生物多样性、种群分布特征与群落演替动态。结果如下:1.在五个航次的样品中共鉴定出硅藻179个种和变种,隶属于53个属,其中赤潮硅藻有27种。8月...The Changjiang Estuary area is the important area of fishery and breed aquacultures, while there have been high frequency of red tide in this area. Diatoms play an important role in the food chain, which are important component of phytoplankton, and some of them are red tide causative species.
