垂直尺度上的污染浓度分布状况越来越受到关注,因此三维大气污染模拟具有非常重要的应用价值.结合三维GIS,采用多面模型与高斯烟羽数学模型集成的方式,通过边界值计算、三角条带构建、多面内插与渲染等技术方法,构建了基于三维的高斯污染扩散系统,探讨了污染物迁移规律和三维模型生成算法,并对某工厂含SO2 有害气体连续排放过程进行了二维与三维模拟,分析了大气污染物质量浓度空间分布特征,并计算得到该污染源大气污染最大落地点距离为206 m.实践表明,采用多面模型表达三维污染物空间分布具有快速、直观的优势,也利于剖面与三维空间分析运算.

The pollution concentration distribution in the vertical scale has been paid more and more attention. So, it is greatly significant to research 3D simulation of atmospheric diffusion in environmental monitoring. With 3D GIS, a Gauss pollution diffusion system, which is based on the Gaussian diffusion model and the multiPatch model, is constructed by boundary value calculation, building triangle strip, multipatch interpolating and rendering. The migration process of air pollution and a 3D diffusion model generation algorithm are also introduced. Moreover, the dynamic diffusion process of SO2 in a factory is simulated by 2D and 3D schemes, based on which the characteristics of spatial distribution are achieved and the maximum landing distance is obtained as 206 m. The practical application of the system shows that the way of 3D simulation based on the multipatch model is effective and suitable for profile computing and spatial analysis in 3D space.
