秦山核电站邻近水域浮游植物的生态研究

Ecological study of phytoplankton in the water area near Qinshan Nuclear Power Station

本文分析了秦山核电站邻近水域生态零点调查四个航次的浮游植物样品,结果表明:调查区浮游植物的种数和细胞密度在时间尺度上均存在明显的季节变化趋势:夏大于秋大于春大于冬,并且与环境因子的变化密切相关,其中最主要的影响因子是温度、盐度和径流,而影响日变化的环境因子主要是潮汐。

We analysed phytoplankton samples from four cruises in the water area adiancent of Qinshan Nuclear Power Station in the present paper.The results suggest that there is a obvious seasonal pattern which appeared as following order: summer> autumn> spring > winter both in number of phytoplankton species and in cell concetration.Such phenomenon has close relationship with environmental factors and the main influential factors are water temperature, salinity, tide and Qiantang River runoff.
