Aermod和ArcGIS在优化区域布局中的综合应用

Integrated Application of Aermod and ArcGIS in the Optimization of Regional distribution

Aermod是导则推荐的大气环境影响预测模式,在环境影响评价中得到了广泛应用,但其存在综合分析和空间呈现功能薄弱的问题。ArcGIS具有较强的空间叠置功能,可弥补Aermod的这一缺陷。将Aermod和ArcGIS综合应用于某工业区环境影响评价中,利用ArcGIS对Aermod大气模拟计算结果进行综合分析和空间叠加,最终将研究区域分为A、B、C 3类区,从大气环境的角度对这3类区域的规划布局提出了建议。最后,对Aermod和ArcGIS在优化区域布局中的应用进行了展望。

As one of the recommended models in the National Technical Guidelines of Environmental Impact Assessment（EIA）,Aermod has been widely used in EIA.However,it is weak in comprehensive analysis and spatial presentation.With powerful spatial overlay analysis,ArcGIS can make up the weakness of Aermod.Aermod and ArcGIS were used in this paper in EIA of an industrial area in shanghai.ArcGIS compositely analyzed the atmospheric numerical simulation results of Aermod.Subsequently,the research area was divided into 3 parts（A,B and C）.The suggestions on general layout of the three parts were proposed based on the atmospheric simulated result.Finally,the optimized combination of Aermod and ArcGIS in regional planning in EIA was prospected.
