中文摘要: 黄海冷水团是我国陆架浅海上一个重要的海洋现象,其季节性生消对浮游植物水华的生态过程产生重要的影响。浮游植物水华决定了海洋生态系统的基础生产力,为整个海洋食物网提供了必要的基础生产。本项目在黄海的历史实测数据、卫星遥感数据和现场航次调查数据综合分析基础上,探讨不同环境因子在黄海冷水团海域硅藻水华生消过程中所起的作用,建立起三维物理-化学-生物耦合数值模型去模拟硅藻水华的动态过程,深入阐明黄海冷水团对硅藻水华生消的影响。本研究对深入探讨黄海硅藻水华发生机制以及预测我国硅藻赤潮以及由硅藻水华引发的其他藻类赤潮都提供了重要的理论基础和技术支持。

英文摘要: The Yellow Sea Cold Water Mass (YSCWM) is a significant phenomenon in Chinese continental shelf neritic zone. Seasonal viability of YSCWM influences the ecological processes of algal blooms. Natural algal blooms, the primary productivity of marine ecological system, provide the basic resources for the entire marine food web. Based on the data analysis of history survey data, satellite remote sensing data and field study data, the roles of different typical environmental factors in the key process from outbreak to decay for diatom blooms are discussed in the region of YSCWM. By establishing a three-dimensional physical-chemical-biological coupling numerical model to simulate the dynamic processes of diatom blooms, this study aims to illuminate the impacts of YSCWA on diatom blooms. The results of this study will help to explain the occurrence mechanism of diatom blooms in the Yellow Sea, and provide an important theoretical foundation and technical support to accurately predict diatom blooms and even harmful algal blooms caused by a diatom bloom.
