摘要: 根据2003年1~12月沈阳逐日大气环境监测数据、气象数据以及AERMOD模式系统建立并验证了空气扩散模型;同时,应用污染源排放清单管理工具软件建立了排放清单,其输出的数据格式满足AERMOD空气扩散模型的要求。验证结果表明:颗粒物的监测日平均值与模拟日平均值的相关性较好,81%的数值落在模拟值与监测值的2倍误差范围内,模拟值与监测值的相关系数为0.68;SO2有72%的数值落在模拟值与监测值的2倍误差范围内,模拟值与监测值的相关系数为0.64。

Abstract: An air quality model of Shenyang was set up and validated using environmental data and meteorological data in 2003 with AERMOD model.An emission inventory was built using an emission inventory management software.The data exporting from the software met the demands of AERMOD model.81 percent of the predicting values of daily average TSP concentration had the errors less than two times errors between the monitoring and the predicting values,and the correlation coefficient between the monitoring and the predicting values was about 0.68.72 percent of the predicting values of daily average SO2 concentration had the errors less than two times errors between the monitoring and the predicting values,and the correlation coefficient was 0.64.
