摘　　要：本研究于2003年5月5日至6日对台湾北部近岸海域,具有地区特征的5个测站进行浮游动物数量、组成等调查研究.结果共发现22大类浮游动物,桡足类为此次调查的主要优势大类,约占总浮游动物个体数量的42.57%,其次为桡足幼体(copep odids),占27.38%,两者在各测站的出现率皆高达100%.根据浮游动物丰度比较、群聚分析与水文状况,可将东北3个测站与西北2个测站分为两个不同的群落.其中,西北部测站可能因沿岸溪流大量有机物的注入,有利浮游动物增生,因此丰度较高,但5个测站的浮游动物多样性皆不高,与台湾其它沿岸海域研究结果相似.This research aims at investigating the composition and abundance of zooplanktonin five geographically distinctive coastal waters of Keelung, Taipei, Taoyuan and Hsin Chu in the northern Taiwan on May 5 to 6, 2003. The results revealed that in all stations, among 22 group of zooplankton recorded, copepod was the dominant group, which accounted for 42.57%. Copepodids was the second dominant group, which accounted for 27.38%. Occurrence of both copepod and copepodids in all stations was 100%. Based on the abundance of major groups of zooplankton, community structure of zooplankton and hydrographical characters, we categorized the zooplankton community into two groups, one belonged to the northwestern communityand the other is northwestern community. The influx of great quantity of organicmatters caused increased zooplankton abundance in the northwestern Taiwan. Thezooplankton diversity was low in all stations, which was consistent with the result of other studies in the coastal waters of Taiwan.
