模拟浮游生物的季节变化

本文讨论了海洋中光合作用过程和计算光合作用的速率方程。运用垂直平均值的浮游生物模型研究了在一个固定站和扩展湾流体系中，浮游植物、浮游动物和营养盐的季节变化。结果表明，夹卷过程将含营养盐丰富的中层水带入了混合层，从而导致浮游植物的生长；摸式较好地给出了扩展湾流体系中的水华季，基本上得到了浮游生物的生活周期。使用不同的参数值进行了若干实验，并对结果进行了讨论。

MODELLING OF THE SEASONAL VARIATION OF PLANKTON

he photosynthetic processes and the rate equation of photosynthesis are discussed in this paper. The seasonal variation of phytoplankton,zooplankton and nutrients at a fixed sta-tion and in the Extended Gulf Stream System are studied by using a vertically averaged plankton model,respectively.The results show that entrainment processes bring the interme-diate water with rich nutrients into the mixed layer to cause the growth of phytoplankton.The model produces the spring bloom in the EGSS well and basically obtains the life cycle of plankton.Several numerical experiments for different values of biological parameters are car-ried out,and the results are discussed.
