摘要:
为了解浒苔绿潮的发展态势、马尾藻分布区与漂移状况,本文基于2016—2017年浒苔暴发季(春末夏初)在黄海绿潮潜在起源区获取的多航次及参考2015年布放定点潜标的环境因子资料,通过高频的精细化硝酸盐监测,对影响黄海浒苔绿潮的起源和发生发展过程中的重要环境要素进行了分析。结果表明:不同年份,黄海浒苔绿潮具有相似的发生发展过程,两个年度的黄海表层硝酸盐分布趋势有差异;年际变化上,2017年绿潮规模较上一年度显著偏小,该年度出现的黄海赤潮、金潮对绿潮规模有一定抑制作用。

Abstract:
Based on the data of environmental factors from multiple voyages and fixed-point buoy about the green tide in the Yellow Sea during the spring to summer in 2016-2017. We focus on the recent progress on the origin and development process of the Yellow Sea green tides. The drifting and distribution of Sargassum horneri were surveyed by multi-disciplinary scientific investigation and research. In the present paper, we analyzed the key biological features of the causative algae and the main environmental factors affecting blooming and drifting of the green algae. The results showed that the bloating green algae of developmental processes were similar, while the impact weaker than 2016, while the impact obvious weaker than 2016, the "Red tide" and "Brown tide" exist at the same time and the trace of nitrate have different. Both of them in the Yellow Sea have certain inhibitory effects on the scale change of the green tide. By analyzing the environmental background of the Subei coastal and the South Yellow Sea to provide in-site data support, we concerned about the causes of the early development of the green tide and the changes in the scale of the green tide. These results can provide decision-making service for environmental management system of marine pollution prevention, ecological protection, and environmental restoration.
Key words:  the Yellow Sea  Green tide  late spring and early summer  environmental factor
