【摘要】 根据对2018年11月(秋季)和2019年3月(春季) 2个航次的海上生态调查,对玉环市周边海域浮游植物、浮游动物和底栖生态的组成、时空分布及多样性进行了分析。结果显示,浮游植物中的优势种为中肋骨条藻(Skeletonema costatum),玉环市东部漩门湾附近海域的浮游植物丰度相对于周边其他海域高,春季浮游植物的丰度稍高于秋季,浮游植物的多样性优于秋季,浮游动物中的优势种为中华哲水蚤(Calanus sinicus),春季浮游动物的丰度低于秋季,可生物量则要高于秋季,秋季玉环南部海域浮游动物的多样性好于玉环周边其他海域,而春季浮游动物的多样性优于秋季;底栖生物中的优势种为异足索沙蚕(Lumbriconeris heteropoda),春季玉环市西部乐清湾海域底栖生物的丰度和生物量高于周边其他海域,春季底栖生物的丰度和生物量都高于秋季,秋季乐清湾海域底栖生物的多样性优于周边其他海域。更多还原

【Abstract】 Based on the marine ecological surveys conducted in November 2018( autumn) and March 2019( spring),the composition,spatial and temporal distribution and diversity of phytoplankton,zooplankton and benthic ecosystems in the surrounding waters of Yuhuan City were analyzed.The results showed that the dominant species of phytoplankton was Skeletonema costatum.The abundance of phytoplankton in the sea area near Xuanmen Bay in eastern Yuhuan City was higher than that in other surrounding areas.The abundance of phytoplankton in spring was slightly higher than that in autumn.The diversity of phytoplankton was better than that in autumn,and the diversity of phytoplankton in autumn was poor.The dominant species of zooplankton is Calanus sinicus.The abundance of zooplankton in spring is lower than that in autumn,but higher than that in autumn.In autumn,the diversity of zooplankton in southern Yuhuan is better than that in other areas around Yuhuan,while in spring,the diversity of zooplankton is better than that in autumn. Lumbriconeris heteropoda,the abundance and biomass of benthic organisms in Yueqing Bay of Western Yuhuan City in spring are higher than those in other surrounding sea areas. The abundance and biomass of benthic organisms in spring are higher than those in autumn,and the diversity of benthic organisms in Yueqing Bay in autumn is better than that in other surrounding sea areas.更多还原
