| 摘要: |
| 文章根据2016年5月（春季）和8月（夏季）温州沿岸海域浮游动物和环境因子的调查资料，对浮游动物的种类组成、生态类群、优势种、丰度和生物量进行研究，并通过典范对应分析探索环境因子对浮游动物群落特征的影响。研究结果表明:春、夏季共鉴定到浮游动物117种和浮游幼虫20类，大多数种类属于暖水性近海类群；春季的优势种包括中华哲水蚤、大西洋五角水母和百陶箭虫，夏季的优势种包括拟细浅室水母、齿形海萤、肥胖箭虫和精致真刺水蚤等；浮游动物的丰度和生物量春季高于夏季，水平分布大致为近岸低、远岸高；浮游动物样品的季节性差异与表层水温和盐度有较大关系，而影响浮游动物群落结构空间差异的环境因子春季为盐度、活性磷酸盐、硝酸盐和氨氮，夏季为盐度、总氮、总磷和叶绿素a。 |

| Abstract: |
| Based on the investigation of zooplankton species and environmental factors in the coastal waters of Wenzhou in May (spring) and August (summer) 2016,the species composition,ecotypes,dominant species,abundance and biomass were analyzed,and the effects of environmental factors on zooplankton community characteristics were explored by canonical correspondence analysis.The result showed that a total of 117 species of zooplankton and 20 groups of pelagic larvae were identified in 2 seasons,most of which belonged to offshore warm temperate group.The dominant species in spring were Calanus sinicus,Muggiaea atlantica,and Sagitta bedoti.The major dominant species in summer were Lensia subtiloides,Cypridina dentata,Sagitta enflata,Euchaeta concinna,et al..The average abundance and biomass in spring were higher than those in summer.In addition,Both the abundance and biomass were lower in nearshore waters than those in offshore waters.The seasonal variability of zooplankton samples related to water temperature and salinity.The principal factors driving spatial differentiation of zooplankton community structure were salinity,Active Phosphate,Nitrate,Ammonia Nitrogen in spring,and salinity,Total Nitrogen,Total Phosphorus,Chlorophyll a in summer. |
