| 摘 要： | 通过海洋动力学和赤潮生物动力学相结合的方法，建立了一个赤潮发生的仿真模型。模型包括水动力、扩用和生物动力学三部分，综合考虑了潮流、营养物质等环境要素的时空变化对赤潮过程的影响，并以大鹏湾夜光藻赤潮为例进行了数值模拟。模型再现了赤潮发生前海水中营养物质的浓度一次明显的增高，而在赤潮发育盛期营养物质降至低谷的现象并反映了赤潮物质容易在海湾的角落等水交换不畅的地域聚集的情况。

| Abstract: | This ecological simulation model of red tide includes water and biologicaldynamics, and takes into consideration environmental factors such as tide,tidal currentand nutntion. The model is a typical water dynamics equations coupled with diffusionand biology equations as follows:where E and N is the nutrient content and red tide biomass in the sea waterrespectively.Numerical simulation is carried out using the Noctiluca scientillans red tide inDapeng Bay as an example. The model reproduces some characteristics of theNoctiluca scientillans red tide phenomenon in Dapeng Bay, in an attempt to clarifythe mechanism and describe the macroscopic process of the red tide occurrence.The model shows that the sea water nutrient content rises obviously before thered tide appears, and falls to the minimum in the period of red tide Peaks. Thisrelates to the fact that large propagation of the red tide organisms needs a greatamount of nutnents.The model also shows that the red tide organisms tend to congregate in the area(such as the comer of the bay) where the water exchange is not strong. |
