基于复杂地形的高斯烟羽模型改进
|
摘要
针对复杂地形条件下化工行业气体泄漏的污染扩散难以预测的问题,基于传统大气扩散的高斯烟羽模型结合空间插值对原有算法进行了改进。以研究区的数字高程模型(DEM)数据为基础,采用C#语言和ArcGIS Engine作为开发工具实现了复杂地形条件下的污染扩散模拟的可视化表达。通过分析不同参数条件下的大气扩散影响,发现地形起伏明显影响地表气体扩散浓度值。相较于传统研究方法,此模拟结果更符合实际大气扩散规律。
When the topography of a region is complex,it becomes difficult to predict the diffusion of pollution caused by gas leakages from the chemical industry. Some improvements were made to address this problem on the basis of a traditional Gaussian plume model and the spatial interpolation method. The ArcGIS Engine and the C# programming language were employed to perform visual simulations of pollution diffusion over complex topography,using a digital elevation model( DEM) of the research area. After analyzing the effects of the atmosphere on different parameters,the results showed that the surface concentration value for gas diffusion was obviously affected by the terrain undulation. Compared with traditional research methods,the results of this simulation are more in line with the laws of actual atmospheric diffusion.
