| 摘要: |
| 目前所了解的众多与发生赤潮有关的因素均非赤潮发生的充分必要条件,而且不存在稳定的赤潮诱发因子。赤潮的发生是富营养化、适合的光合作用条件和赤潮藻本身的死亡率三方面的综合结果。这3个因素以及与这3个因素有关的其他因素都可能成为赤潮发生的激发因子。根据此概念建立了赤潮生消过程的动力-营养盐-赤潮藻间的耦合数值模式,成功地数值模拟了1998年3–4月在香港沿海实际发生的赤潮生消的全过程。该模式对于研究赤潮的发展过程及预报是有益的探索。 |

| Abstract: |
| Based on the idea that the presently known factors related to red tide algal bloom are not a sufficient and necessary condition, there is no definite trigger to the bloom. It is a comprehensive result of eutrophication, suitable photosynthesis condition and algal natural mortality. These factors are the basis and other factors are auxiliary factors. Each of these basic and auxiliary factors can be a trigger depended on the environment, which is indicated in the numerical simulation of red tide appeared at the sea off Hong Kong from March to April of 1998 using a coupled model of dynamics, nutrient and red tide algae. |
