外源输入对大亚湾大鹏澳浮游生物影响的模拟研究

An initial numerical study on the effect of input by outer source on the plankton in Dapeng'Ao Cove, Daya Bay

本文通过建立一个简单的浮游植物、浮游动物和营养盐动力学数值模型,根据大亚湾大鹏澳秋季一个月的连续观测资料,利用线性回归分析法来求得上述动力学数值模型的一些主要参数,结果表明,降雨及陆源输入是导致该海区营养盐增加的一个重要因子;根据上述参数进行的数值模拟结果与实测结果基本吻合,同时也表明,降雨及陆源输入对该海区浮游植物和浮游动物的分布规律影响较大。

In the paper, a simple dynamic numerical model of phytoplankton, zooplankton and nutrient is set up. Based on the continuous monthly observational data in autumn, the linear regression analyses method is used to calculate some major parameters in the dynamic numerical model, it is shown that, the input by precipitation and runoff is an important factor that brings about the increase of nutrient in this sea areas. The numerical simulation results based on the above calculated parameters agree with those observed ones basically, and it is also shown that, the input by precipitation and runoff has a larger effect on the distribution rule of phytoplankton and zooplankton in this sea areas.
