为了评估不同人为活动对浮游动物和浮游生态系统的影响，于2010年对象山港中型浮游动物群落的空间异质性进行了季节性调查。评估包括五个不同的领域：海带养殖场，牡蛎养殖场，养鱼场，电厂的热排放区，和人工鱼礁，我们的目的是确定是否人为活动占主导地位的浮游动物群落的空间变化。结果表明，研究区域的中型浮游动物群落之间存在明显的空间异质性，主要是由自然水文特性驱动，除了在该地区附近的热排放口的电站。在出口区域，排放引起的热冲击影响了中型浮游动物群落的丰度和生物量下降，在整个四季，甚至导致在出口附近的优势种在夏季从太平洋纺锤水蚤广温和温水类群的转变。牡蛎养殖场中型浮游动物群落的独特性可能是由于牡蛎养殖和分支港自然环境的共同影响。然而，到2010年，海带和鱼类养殖以及人工鱼礁的建设并没有对中型浮游动物群落产生任何明显的影响，这可能是因为水产养殖规模较小，人工鱼礁的修复效果存在时滞。因此，象山港浮游动物群落空间变化的主导因素仍是自然水文特征，但温排水是改变海洋生态系统的人为活动，应加强监测。
To evaluate the effects of different anthropogenic activities on zooplankton and the pelagic ecosystem, we conducted seasonal cruises in 2010 to assess spatial heterogeneity among the mesozooplankton communities of Xiangshan Bay, a subtropical semi-enclosed bay in China. The evaluation included five different areas: a kelp farm, an oyster farm, a fish farm, the thermal discharge area of a power plant, and an artificial reef, and we aimed to identify whether anthropogenic activities dominated spatial variation in the mesozooplankton communities. The results demonstrated clear spatial heterogeneity among the mesozooplankton communities of the studied areas, dominantly driven by natural hydrographic properties, except in the area near the thermal discharge outlet of the power station. In the outlet area, thermal shock caused by the discharge influenced the mesozooplankton community by decreasing abundance and biomass throughout the four seasons, even causing a shift in the dominant species near the outlet during summer from Acartia pacifica to eurythermal and warm water taxa. Unique features of the mesozooplankton community in the oyster farm may be due to the combined effects of oyster culture and the natural environment in the branch harbour. However, kelp and fish culture, and the construction of an artificial reef did not exert any obvious influence on the mesozooplankton communities up to 2010, probably because of the small scale of the aquaculture and a time lag in the rehabilitation effects of the artificial reef. Thus, our results suggested that the dominant factors influencing spatial variations of mesozooplankton communities in Xiangshan Bay were still the natural hydrographic properties, but the thermal discharge was an anthropogenic activity that changed the pelagic ecosystem, and should be supervised.
