摘　　要：为了解东寨港保护区浮游动物的群落结构,于2010年3月和9月在海南东寨港红树林保护区海域的25个采样点采集了浮游动物样本,共鉴定出浮游动物72种,浮游幼虫22种,其中,以甲壳动物最为丰富.3月的优势种共有9种,生物量平均值为98.84 mg·m^(-3),平均丰度为58个体/m^3,Shannon-Wiener多样性指数和Pielou均匀度指数的平均值分别为3.545和0.619.9月的优势种为4种,生物量平均值为202.72 mg·m^(-3),平均丰度为270个体/m3,Shannon-Wiener多样性指数和Pielou均匀度指数的平均值分别为3.123和0.538.在综合分析浮游动物的生物量、丰富度、Shannon-Wiener多样性指数、Pielou均匀度指数后,初步判定东寨港秋季的污染程度大于春季的污染程度,整体海域未受到污染,但近岸受到轻微污染.To understand zooplankton communi ber 2010, the zooplankton samples were collec ty structure of Dongzhai Harbor, during March 2010 and Septem- ted at 25 sample points from the coastal waters. The result showed that 72 species of zooplankton and 22 groups of planktonic larvae were identified, among which Crustaceans were the most diverse. During March, there are 9 dominant species, the average of biomass was 98.84 mg· m-3, the average of abundance was 58 ind · m-3, the average of Shannon - Wiener diversity index and Pielou evenness index was 3. 545 and 0.619 respectively ; during September, there are 4 dominant species, the average of bio- polluted, however, the nearshore water was slightly polluted.
