海洋浮游生态系统动力学模式的研究

PROGRESS IN MARINE PLANKTONIC ECOSYSTEM MODELLING

分析了海洋浮游生态系统动力学模式的结构，讨论了其研究现状。９０年代以来海洋浮游生态系统动力学模式的特点是：状态变量的个数较以前有所增加，从２－４个增加到３－７个，生物过程的描述更加细致；注意刻画物理过程的作用，特别是垂直方向上湍流的交换作用；利用或改进原来的模式，研究新问题；模式仍以一维为主，同时三维耦合模式也得到发展和应用；研究区域仍以北大西洋为主，也出现了研究赤道太平洋、阿拉伯海、东海等海区的工作。

The structure of marine planktonic ecosystem models is discussed. The progress in marine planktonic ecosystem modelling in the 1990s is also reviewed and compared with earlier studies on modelling. The featuress of marine planktonic ecosystem modelling in the 1990s are as follows. The numbers of state variable have increased from 2-4 to 3-7. Emphasis has been placed on the role of physical foreing to ecosystem, and the turbulence mixing in the vertical direction is parameterized according to a turbulence scheme in many models. Most of the studies are based on the madals developed in the 1990s, still some on the models appearing before 1990 or the modified version of the old models. One-dimensional models contribute to a great part of the references and there have been several studies of 3-dimension physical-biological modelling. Most of the studies focus on the North Arctic Ocean and some are applied to broad areas such as Equatorial Pacific, the Arabian Sea and the East China Sea.
