摘要
针对水污染运移仿真表现力不强的问题,采用复杂性理论思想,在干流河道多尺度分解的基础上形成水质体积微元,建立具有吸附行为、自净行为、沉降行为、挥发行为、平推行为、扩散行为和演化行为的复杂agent模型,开展基于高性能计算技术的agent计算力优化,实现以多agent涌现为特征的污染物运移仿真模拟,并在数字地球上进行可视化表现。实验表明,该方法能够有效反映污染物的演化状况,并可以汇集3S所提供的地形地貌数据,更加丰富直观地表现水污染运移过程。
According to the deficiency in simulation of water pollution transport,adopting the complexity theory,this paper formed a water quality triangle infinitesimal according to the multi-scale decomposition of watercourse. It built the complex agent model with adsorption behavior,self-purification behavior,settlement behavior,volatilization behavior,plug-flow behavior,diffusion behavior and evolution behavior. It optimized the calculation power resource of agent by the high performance computing technology,and implemented the contaminant transportation simulation by taking the emergence of multiple agents as a character,and displayed in the digital earth. The experiment results show that this method can effectively express the status of pollutants evolution,and describe the migration process of water pollution more intuitively with topography data collected and provided by 3S.
