中文摘要:
      利用2009-2018年在南黄海苏北浅滩海域的现场调查数据,分析和研究了该海域漂浮绿藻和马尾藻的长期变化和季节性波动特征。研究显示,漂浮绿藻于每年4月中旬至下旬在浅滩中部筏架周围开始出现。5月-6月,漂浮绿藻生物量迅速增加,并漂移扩散至深水区。漂浮绿藻密度年际变化较大,但这十年间总体呈上升趋势。相比较而言,漂浮马尾藻仅在2013、2017和2018年在浅滩聚集形成春季藻华;且这三年,漂浮马尾藻密度超过同期漂浮绿藻。浅滩漂浮马尾藻的发生与发展过程与漂浮浒苔明显不同。3月,漂浮马尾藻开始出现于浅滩离岸海域,4-5月,漂浮马尾藻大量侵入浅滩,因此浅滩漂浮马尾藻现并非起源于本地。受高强度人类活动以及浅滩以外海域物理化学和生物过程的影响,浅滩环境因素与漂浮绿藻生物量的关系不甚明确。对于漂浮马尾藻的起源以及与漂浮绿藻的相互关系也需要进一步研究。
英文摘要:
      The data of field surveys during 2009 to 2018 was analyzed to understand the seasonality and inter-annual variability of the floating Ulva and Sargassum in the Subei Shoal, the southwestern Yellow Sea of China on decadal scale. The floating Ulva biomass was consistently originated from the central region of the Subei Shoal in middle to late April, increased rapidly, drifted and extended into the offshore water in May and June. The average floating Ulva biomass in the shoal generally increased over the years with evident inter-annual fluctuations. In contrast, pelagic Sargassum was accumulated in the Subei Shoal and formed the spring bloom only in 2013, 2017 and 2018, and the biomass was higher than the co-occurring Ulva during the survey in these three years. Compared to the raft-origin floating Ulva, genesis and development of the pelagic Sargassum was distinct. Based on the current research, the Sargassum biomass was exotic and often initiated in the offshore water in March, and intruded into the shoal in April and May. The analysis on the environmental parameters was inconclusive since multiple anthropogenic and non-indigenous factors could influence the green tides in this region. Further research covering both the East China Sea and the Yellow Sea is needed to trace the origin of the floating Sargassum and to understand the interactions between these two co-occurring seaweeds.
