摘要： 对洋山港航道浮游动物进行季节变化调查。结果显示，浮游动物密度呈夏季最高，春、秋季次之，冬季最低，且春季生物密度较秋季稍高。优势种共发现有6种，其中四刺窄腹剑水蚤（Limnoithona tetraspina）为全年优势种，且在冬季优势最强，优势度为0.48，夏季最弱，优势度为0.04。克氏纺锤水蚤（Acartia clausi）为春、秋、冬季优势种，太平洋纺锤水蚤（Acartia pacifica）为夏季和秋季的优势种，针刺拟哲水蚤（Paracalanus aculeatus）为夏、秋、冬季优势种，帚毛虫（Sabellaria）仅为春季优势种，小拟哲水蚤（Paracalanus parvus）为秋季优势种。针刺唇角水蚤（Labibocera euchaeta）已不再是优势种，洋山港受人为影响严重。

Abstract: A zooplankton seasonal variation investigation was made in Yangshan Port channel. Zooplankton density was the highest in summer. Spring biological density was fall slightly higher. There were 6 dominant species in result. One of the species Limnoithona tetraspina was the dominant species throughout the year. And it was the most obvious in winter(Y=0.48), the least obvious in summer(Y=0.04). The Acartia clausi was the dominant species in spring, autumn and winter. The Acartia pacifica was the dominant species in summer and autumn. The Paracalanus aculeatus was the dominant species in summer, autumn and winter. The Sabellaria was the only dominant species in spring. And the Paracalanus parvus was the only dominant species in autumn. However, the Labibocera euchaeta was not the dominant species anymore. So Yangshan Port was affected by human.
