东海北部海洋浮游生态系统季节变化的模拟研究
发布时间：2021-10-24 22:29
作为生物圈的重要组成部分,海洋生态系统在连接大气圈和岩石圈中扮演着重要的角色,同时也是海洋物质循环和能量流动中的重要组成部分。东海是中国典型的大陆架边缘海,常年受到长江冲淡水、近岸水团和外海洋流的影响,其水文条件和生物地球化学过程十分复杂。研究者们通常结合实地观测数据和三维物理-生物地球化学耦合模型,来研究东海海洋生态系统,但目前,尚缺乏对东海局地海洋生态系统的时空变化的高分辨率研究。本研究基于GOTM、ERSEM模型,在东海北部（125°E,31°N）建立了浮游生态系统要素的垂向一维模型,并动态模拟了这些要素的季节、垂向变化。通过分析该区域浮游群落结构的季节、垂向的变化,分析了要素间的相互作用和反馈机制,讨论了控制这些过程的主控因子和协同作用,发现光照和营养盐对浮游生态系统的季节性变化存在显著性影响,从而为未来扩展到三维模型的应用奠定了基础。模拟结果显示,东海的物理场和营养盐的模型数据和观测数据的对比具有良好的一致性,说明该模型可以较真实的模拟东海的物化环境。其次,我们还分析了浮游生物的生物量的季节、垂向变化。在此基础上,探讨了浮游生态系统的主要要素间的相互作用和反馈机制,并进一步分...
