基于CA-MAS的水域总有机碳扩散模拟研究

当前水环境污染扩散研究一般基于普通数值模型模拟,忽略了水污染扩散微观驱动力的影响。为能更真实地反映其动态扩散过程,针对水域总有机碳(TOC)扩散机理,基于CA和MAS技术,将影响TOC扩散的自然和社会经济因素抽象为微观的水流Agent、风速Agent、径流量Agent、污水排放口Agent、人工管理Agent以及农业生产地Agent,将研究水域抽象为CA元胞空间,建立了CA-MAS水域总有机碳扩散模型,对水域总有机碳的动态演化过程进行模拟,并以武汉理工大学鉴湖水域作为实验区域,借助NetLogo仿真平台完成了模型的实现与验证。模拟结果表明,该模型基本能够反映水体总有机碳的扩散规律,可以为水环境污染控制提供参考。

TOC diffusing simulation in water environment based on CA-MAS model

Nowadays, the current researches on the diffusion of water pollution are usually based on general numerical simulation model, which have ignored the impact of microscopic driving forces on water pollution diffusion. In order to reflect the dynamic diffusion process of water pollution in a more realistic way, we build a CA-MAS diffusing simulation model according to the mechanism of the total organic carbon (TOC) diffusion in water environment combining multi-agent systems (MAS) with cellular automata (CA). In this model, natural and social influencing factors of TOC diffusion are expressed as flow agent, wind agent, runoff agent, sewage outfall agent, management agent and agricultural agent, and the study area is abstracted as cellular space. Furthermore, Jianhu Lake in Wuhan University of Technology was taken as research area; the implementation and verification of this model were performed by NetLogo software. Finally, the result of simulation shows that CA-MAS model can basically reflect the rule of TOC diffusing in water environment; meanwhile, it can provide theoretical reference for the control of water pollution.
