摘要
随着我国汽车工业的快速发展和机动车拥有量的急剧增长,汽车尾气污染给城市环境带来巨大的影响,目前国内各大城市机动车排气污染危害日益严重,而汽车尾气污染最为严重的地段则首当城市交叉口。基于这样的宏观背景,本文以OSPM模式及Nichoson箱式模型的修正形式为基础开发了十字交叉口和T型交叉口的机动车尾气扩散模型并通过实测数据进行了验证,结果表明该扩散模型具有较强的可操作性,其应用将为汽车尾气污染的预防及控制提供强有力的技术支撑。
Automotive exhausts emission have serious impact on urban environment with the rapid development of automobile industry and the increase of vehicle population.Now all large cities at home are polluted more and more seriously,and the sites which are polluted most seriously are urban intersections.Based on this background,the diffused model of vehicle exhausts for cross intersection and T-intersection is built combined with OSPM mode and Nichoson revised model,then the model is validated by survey data and the result shows that it has obvious advantage in the practical operation.
