秦山核电站邻近水域浮游动物的生态特点

本文根据春、夏、秋、冬四个季度月(1989年4、7、10月和1990年1月)在秦山核电站邻近水域大面观测站上所采集的浮游动物样品,对该测区浮游动物的生物量和种类组成以及与环境因子间的关系作了分析探讨。

Ecological characteristics of zooplankton in the waters near Qinshan Nuclear Power Station

The samples of zooplankton from 23 stations were analysed during the survey of zero ecology in the waters off the Qinshan Nuclear Power Station in April, July, October (1989) and January (1990) .The biomass and the individual density of zooplankton were 145. 3 mg / m3 and 318. 8ind. / m3 in annual average. The most dominant group was Copepoda (amouted to 91.8% of the total zooplankton individuals).The zooplankton species in the surveyed area were all belong to the low salinity community of estuary.Tortanus vermiculus, a brackish-water copepoda, was the most dominant species, which amouted to 22.9%, 80.8%, 71.6% and 66.7%of the total individuals respectively in spring, summer, autumn and winter. In addition , the relationship between the zooplankton distribution and the environmental factors was discussed in the paper.
