摘 要：
根据2002—2003年在东海近海28°00′N—32°00′N、122°00′N—123°30′E4个季节的海洋调查,探讨了东海近海浮游多毛类总丰度和种类变化的季节特征以及这些变化与水团的关系、优势种的数量变动和对多毛类的贡献和优势种的环境适应等,并与东海外海多毛类的生态特征做了比较。结果表明:该海域浮游多毛类总丰度具有明显的季节变化;夏季平均丰度最高(1.30ind·m-3),分布范围最广,春季平均丰度最低(0.04ind·m-3);调查共发现15种浮游多毛类,盲蚕(Typhloscolex muelleri)、明蚕(Vanadis sp.)和泳蚕(Plotohelmis capitata)是优势种,其中盲蚕是四季的优势种,夏季和冬季的优势度较高分别为0.16和0.1,明蚕仅是夏季的优势种,泳蚕仅是秋季的优势种;盲蚕在春、冬季贡献率较高,分别为1和0.94,占绝对优势,更适应暖水广盐的环境;东海近海浮游多毛类具有种类数变化大,种类组成多样的特点;不同季节数量变化较大,平面分布格局各不相同。

摘 要：
Based on the data of four seasons investigations in the coastal waters of the East China Sea (28°00′ N-32°00′N, 122°00′ E-123°30′E) from 2002 to 2003, this paper studied the seasonal characteristics of the changes in total abundance and species of pelagic polychaetes, the relationships between these changes and water masses, the quantitative changes of dominant species and their contribution to polychaetes, and the environmental adaptation of dominant species, with the ecological characteristics of pelagic polychaetes in the outer East China Sea compared. The results showed that the total abundance of pelagic polychaetes in study area had an obvious seasonal change, with the highest average abundance (1.30 ind·m-3) in summer and the lowest (0.04 ind·m-3) in spring. A total of 15 species of pelagic polychaete were identified, and Typhloscolex muelleri, Vanadis sp., Plotohelmis capitata were the dominant species. Among the dominant species, only T. muelleri appeared in four seasons, and its dominance was higher in summer and winter, being 0.16 and 0.1, respectively. Vanadis sp. only appeared in summer, while P. capitata was in autumn. The contribution of T. muelleri was higher in spring and summer, being 1 and 0.94, respectively, which suggested that this species adapted well in warm waters and euryhaline environment. Our study indicated that the complex species composition and the greater spatio-temporal change in species number were the characteristics of pelagic polychaetes in the coastal waters of the East China Sea.
