【摘要】 介绍了《环境影响评价技术导则大气环境》(HJ2.2-2008)推荐预测AERMOD模式与93导则推荐高斯模式的一般原理,通过大气稳定度、复杂地形处理和对流条件下污染物扩散等原理的比较,分析两种模式的功能及适用范围。并以某水泥厂的数据资料为基础数据,分别采用AERMOD模式与93导则推荐的高斯模式计算小时预测浓度和日均预测浓度。通过预测数据的对比,分析两种预测模式的预测精度和可靠性。更多还原

【Abstract】 This paper introduced the general principles of prediction AERMOD model in"Technical Guidelines for Environmental Impact Assessment of Atmospheric Environment"(HJ2.2-2008) and prediction model recommended by Gaussian guidelines.In terms of atmospheric stability,complex terrain handling and pollutant dispersion principles under convective conditions, this paper analysis the functions and scope of application of two models.Base on statistical data of one cement plant,calculate hours predicted concentration and daily predicted concentration by AERMOD model and model recommended by 93 guidelines respectively.Through the comparison of forecasts,analysis of two kinds of prediction model forecast accuracy and reliability.更多还原
