| 中文摘要: |
| 本文以栅格数据结构为基础，采用二维元胞自动机模型模拟水体中污染带的扩散漂移。通过确定元胞空间和元胞状态，在进一步考虑流场和风场因素对水体里污染带扩散漂移影响的基础上，建立了污染带扩散漂移规则，并根据该规则以8邻域方式进行元胞状态的更新，从而建立了基于元胞自动机原理的污染带扩散和漂移的时空模型。最后采用该模型对突发性水污染事故进行了动态模拟。预报了污染物质的漂移轨迹和时空动态变化。 |
| 英文摘要: |
| On the basis of grid spatial data structure the two dimensional cellular automata model is applied to simulate the drift diffusion of pollution zone in water. By determining the space location and state of cellular and taking the effect of wind field and flow field on drift diffusion into account the space and temporal model of water pollution zone drift diffusion based on cellular automata principle is established. In the model the rule of continuously updates the 8 neighbor cellular state is adopted. The model is applied to simulate the dynamic variation process of a water pollution accident. The drift trajectory and spatial temporal variation process of the pollution zone are predicted. |
