渤海湾赤潮特征研究

Characteristics of red tide in the Bohai Bay

摘要: 对1977年至2018年渤海湾发现的赤潮进行统计，分析研究了赤潮的规模变化、引发物种、空间分布以及时间规律特征。结果表明：渤海湾赤潮多为面积在1000 km²以下的小规模赤潮，引发物种主要是夜光藻（Noctiluca scintillans）、中肋骨条藻（Skeletonema costatum）、叉角藻（Ceratium furca）、球形棕囊藻（Phaeocystis globosa）、米氏凯伦藻（Kareniamiki motoi）和红色中缢虫（Mesodinium rubrum），主要暴发地点为渤海湾西北近岸海域，高发期为8月—9月。

Abstract: Analysis of the scale of change, the causative species, spatial distribution, and temporal characteristics of the Bohai Bay red tides during the period of 42 a from 1977 to 2018 showed that most of the red tides in the Bohai Bay were small-scale with area of less than 1000 km². The main species that caused the red tides were Noctiluca sintillans, Skeletonema costatum, Ceratium furca, Phaeocystis globosa, kareniamiki motoi and Mesosinolum rubrum. The red tides primarily happened between August and September in the northwest coastal area of the Bohai Bay.
