摘　　要：高斯烟羽模型是模拟大气点源污染扩散的重要方法。然而,该模型主要解释了污染物在大气中扩散的机理,难以揭示空气污染扩散的直观过程与结果。为了能够更直观地观察大气污染扩散过程与结果,有必要将GIS技术与环境模型相结合应用于大气污染扩散模拟中。这样不仅发挥了GIS的强大空间可视化管理和分析功能,也能为环境模型的模拟、预测和分析提供高效的决策支持平台。为此,本研究基于空间插值分析方法和高斯烟羽模型,利用ArcEngine组件开发大气污染扩散模拟系统。试验表明,结合GIS能够较好地完成基于高斯烟羽模型的大气污染扩散模拟,并且完成模拟结果的可视化分析,为相关环境管理部门提供了一套界面友好且操作简单的大气污染扩散的空间决策支持模拟平台。Gaussian plume model is an important method to simulate the diffusion of atmospheric point-source pollution.However,this model gives the explanation of the mechanism how the pollution diffuses in the atmosphere,and it is difficult to reveal the intuitive processes and consequences of the spreading of air pollution.As such,in order to observe the processes and results of air pollution diffusion more directly,it is necessary to integrate the GIS and environment model to simulate the diffusion of atmosphere pollution.This not only brings into play the powerful spatial visualization and analysis function of GIS,but also provides an efficient decision support platform for the simulation,prediction and analysis of environmental models.In this study,based on spatial interpolation analysis method and Gaussian plume model,ArcEngine components were used to develop atmospheric pollution diffusion simulation system.The experiments show that the combination of GIS can simulate the air pollution diffusion based on the Gaussian plume model well,and complete the visualization analysis of the simulation results,which provides a set of friendly interface and simple operation spatial decision support simulation platform for the air pollution diffusion for related environmental management departments.
