摘　　要：对2006年夏季渤海湾赤潮重点监控区发生的夜光藻赤潮的生消过程进行了初步分析和研究,结果表明,在赤潮的整个生消过程中,3个站位的pH值、叶绿素-a含量、溶解氧、化学耗氧量和营养盐的变化均与夜光藻快速增值前浮游植物的迅速生长有关,浮游植物进行生长时大量吸收水体中的营养盐,而温度和盐度对此次赤潮的生消不存在明显影响。同时,水文气象因子的变化是此次赤潮的发生和消亡时必不可少的条件。The process of Noctiluca scintillans red tide has been studied in the dominant area of red tide monitoring in Bohai Bay in summer, 2006. The results showed that pH, chlorophyll-a contents, dis- solved oxygen, COD and nutrient in the three stations are concerned with the quick increase of phyto- plankton before the increase of Noctiluca scintillans, and nutrients have decreased because of the ab- sorption from phytoplankton, but there is no obvious influence of temperature and salinity for this red tide. At the same time, Hydrology and atmosphere factors are necessary for the happening and dying of this red tide.
