摘要
重点开展基于虚拟地理环境的空气污染扩散模拟与交互操作研究,为城市空气污染的管理和时空动态模拟提供一个良好的可视化分析环境。以珠江三角洲空气污染为案例,建立虚拟地理环境原型系统,开展空气污染动态扩散模拟,进行实时交互查询与分析,实验结果证明,本文的方案能够逼真地模拟大气污染扩散过程,能较好地揭示城市群间空气污染的相互影响规律。
This paper focus on how to build a virtual geographic environment for simulation and interactive operation of air pollution dispersion in city clusters,A visual analysis environment was offered to manage city air pollution resource and implement spatio-temporal simulation.With a case study on the PRD(Pearl River Delta) region,China,a prototype system is developed to construct a virtual geographic environment for simulating air pollution dispersion.Experimental results prove that the scheme addressed in the paper is effective and feasible.It can efficiently demonstrate the interaction and mutual contribution of city air pollution among city clusters.
