摘　　要：2002年5月和月对上海市金山三岛海域浮游动物进行了调查研究,结果表明:两个航次共鉴定8浮游动物21种,其中桡足类种,水母类种,糠虾类种,端足类、等足类各种,浮游幼虫类73223种,其它种。虫肢歪水蚤、火腿许水蚤为平水期和丰水期的主要优势种类,优势度分别为30.45和0.43。平水期和丰水期浮游动物个体密度平均分别为124.13ind./m3和335.30ind./m3;平均生物量分别为230.00和190.75mg/m3。多样性指数(H′)偏低,平均值小于。该海域浮游动物类群是一个沿岸低盐群落。与2邻近海域相比,该海域浮游动物种类组成比较单一,个体数量较多,但生物量相对较低。The investigated results show that there are 21 the species in Jinshan-Three-Island sea area. copepod: seven, medusad: three, euphausiacea: two, hyperiidea: two, isopoda: two, planktonic larvae: three, others: three in May and August, 2002. Tortanus vermiculus is the dominant species in the normal flow period, and in the wet season Schmackeria poplesiai is dominant. The dominance is 0.45 and 0.43. The average density is 124.1 and 335.3 ind./m3 in the normal flow period and the wet season, the average biomass is 230 and 190.75 mg/m3. Its diversity index (H') is on the low side (less than 2). Zooplankton ecotype of Jinshan-Three-Island sea area is a nearshore and low-salinity cluster. Compared with the neighborhood, the species is simple, and the individual number is more, but the biomass is lower comparatively.
