大亚湾核电站邻近水域浮游纤毛虫群落结构

应用蛋白银染色法及沉淀法分别对采自大亚湾水域的浮游纤毛虫进行了定性和定量分析．根据各样点浮游纤毛虫群落的结构参数确定了该水域浮游纤毛虫群落有以下特点：群落的种类数从９～２９种不等，密度从２０００～１３４００ｉｎｄ／Ｌ；群落的优势种为腹羽急游虫（Ｓｔｒｏｍ－ｂｉｄｉｕｍｖｅｎｔｒｏｐｉｎｎｕｍ）和球形急游虫（Ｓｔｒｏｍｂｉｄｉｕｍｓｔｒｏｂｉｌａ）；群落的生物多样性指数为２．７１３２～４．２３３９．并结合采样点的位置分析了大亚湾核电站冷却水对浮游纤毛虫群落的影响．

Community Structures of Planktonic Ciliates in the Water Near to Dayawan Bay Nuclear Power Plant

The methods of Protargol staining and sedimental counting were adopted in quantitative and qualitative analyses of planktonic ciliates from Dayawan Bay Based upon the structural parameters of the planktonic ciliates, some characteristics of planktonic ciliate communities are shown as follows: the planktonic ciliate communities were composed of 9 to 29 species of ciliates; the abundances were from 2 000 to 13 400 ind/L; the dominant species of the communities were Strombidium ventropinnum and Strombidium strobila ; and the community biodiversity indices were from 2 713 2 to 4 233 9 The influences of cooling water from Dayawan Nuclear Power Plant on the planktonic ciliate communities were analyzed as well.
