摘要:
］通过实测，确定机动车排放因子，计算道路线源污染源强.结合GIS技术，应用HIWAY2、CALINE4模型模拟厦门市区机动车尾气NOx、PM10的扩散，并验证与分析模拟结果.研究表明，选取的扩散模型对PM10的模拟值比实测值平均偏低4.03 ％，对NOx的模拟值比实测值平均偏高1.98 ％，即所用模型能较准确地定量模拟厦门市区机动车尾气污染扩散状况
Abstract:
The proportion of atmospheric pollution caused by automobile emission tends to become greater.It is useful to simulate the pollutant diffusion due to automobile on city roads. After identiying emission factors by testing,the intensity of road traffic pollutant was calculated. Based on GIS technology,the models of HIWAY2 and CALINE4 were used to simulate NOx and PM10 produced by automobile in urban area of Xiamen City.The pollution concentration simulated was validated and anlyzed through measure.The experiment result showed these models were suitable,and they could quantificationally reflect the spatio-temporal pollutant diffusion with high precision.In the course of environmental modeling,GIS technology could offer enormous help for database building,parameters obtaining,and intuitionistic visualization of the simulated result
