１９９５年１０月～１９９６年７月对秦山核电站Ⅲ期工程邻近水域进行了４个季度月的综合调查。共获得底栖生物５２种，生物量和栖息密度分别为０．０６ｇ／ｍ２和４．２８个／ｍ２，季节变化明显。群落结构表现出河口性广温低盐的生态特征。代表种为安氏白虾、葛氏长臂虾和棘头梅童鱼。探讨了底栖生物种类和数量分布与环境因子之间的关系。 From October 1995 to July 1996, a total of 4 quarterly surveys were conducted on the adjacent waters of Phase III of Qinshan Nuclear Power Station. A total of 52 species of benthic organisms were obtained, their biomass and habitat density were 0.06g / m2 and 4.28 / m2 respectively, with obvious seasonal changes. The community structure shows the ecological characteristics of estuary wide temperature and low salt. The representative species are white shrimp, gekko shrimp and spine head plum fish. The relationship between species and quantity distribution of benthic organisms and environmental factors was discussed.
