| 摘 要： | 采用2011年3月27日-4月3日调查资料，对三亚湾海域浮游动物的种类组成、优势种、生物量、密度、多样性指数和均匀度等分布特征进行分析。结果表明，本次调查鉴定浮游动物68种，优势种为桡足类的瘦歪水蚤（ Tortanus gracilis）、太平洋纺锤水蚤（ Acartia pacifica）、美丽大眼剑水蚤（ Corycaeus speciosus）、小哲水蚤（ Nannocalanus minor），微刺哲水蚤（Canthocalanus pauper），锥形宽水蚤（Temora turbinata）；毛颚类的百陶箭虫（Sagitta bedoti）和肥胖箭虫（Sagitta enflata）；介形类的针刺真浮萤（Euconchoecia aculeata）；被囊类的异体住囊虫（ Oikopleura dioica）；樱虾类的中型莹虾（ Lucifer intermedius）。生态类群主要以暖水沿岸种类为主。三亚湾浮游动物密度和生物量分布呈现由河口沿着三亚湾向外海再到鹿回头沿岸呈逆时针逐渐减少趋势，且湾内大于湾外；三亚湾浮游动物的密度与重金属铜呈极显著正相关，与水温呈显著正相关，与活性磷酸盐呈极显著负相关，与盐度呈显著负相关；浮游动物生物量与悬浮物、叶绿素a、铜呈显著正相关，与盐度呈显著负相关。

| Abstract: | The distribution characteristics, the species composition, dominant species, biomass, density, diversity index and the evenness were analyzed, according to the data which was investigated in March 28 to April 3, 2011. The results showed that, there were 68 species of zooplankton was identified in this investiga-tion. And the dominant species was the copepods such as Tortanus gracilis, Acartia pacifica, Corycaeus speci-osus, Nannocalanus minor, Canthocalanus pauper and Temora turbinata, chaetognatha such as Sagitta bedoti and Sagitta enflata, ostracoda such as Euconchoecia aculeata, tunicate such as Oikopleura dioica, sergestid-ae such as Lucifer intermedius. The mainly ecological characteristics of zooplankton was neritic warm water species. The distribution of the biomass and the density of zooplankton in Sanya Bay have showed a trend such as counterclockwise to reduce gradually from the estuary along the Sanya Bay to the outside sea, then to the coastal of Luhuitou, and the inner bay were more than the outer bay. The density of zooplankton was signifi-cant positive correlation with the heavy metal Cu, positive correlation with the water temperature, and was significant negative correlation with active phosphate, negative correlation with salinities. The biomass of zoo-plankton was significant positive correlation with the suspended matter, Chlorophyll a and Cu, was negative correlation with salinities. |
