| 摘 要： | 作者对秦山核电站邻近水域进行了春、夏、秋、冬(1989年4月～1990年1月)四个航次的综合调查。结果表明,该区域大型底栖动物的生物量和个体数量极为贫瘠(分别为0.03g/m~2和2.0个/m~2),生物种类组成简单,经鉴定有33个种类,并有明显的季节变化。底栖动物群落结构表现出鲜明的河口或近岸性广温低盐的生态特点。属杭州湾的白虾—长臂虾群落,夏季棘头梅童鱼Collichthys lucidus占绝对优势。水动力因子、沉积作用和盐度是决定调查区域底栖动物种类、数量和分布的关键因子,而季节变化则主要受温度所控制。

| Abstract: | Benthic macrofauna in the area near Qinshan Nuclear Power Station were investigated for four cruises during April 1989-Jane 1990.
The results show that macrobenthos in this area is extremely poor, average biomass and density are 0.03 g/ m2and 2.0 ind/ m2 respectively. The species composition is also simple, a total of 33 species of macro fauna were found from 1 970 individuals. Seasonal variation is obviously. Community structure could belong in Exopalaemon annandulei- Palaemon gravieri Community of Hangzhou Bay which strongly reflects estuarine low salinity and eurythermal ecological characteristics.
Environmental factors which affect macrofauna ecological changes of investigated area are referred to as temperature, salinity, sedimentation and hydrographic dynamics, the authors consider that hydrographic dynamics and salinity are the key factors to determine the abundance of species and distribution of animals, however, seasonal variation is controlled by temperature. |
