为了研究我国平原地区高速公路两侧的机动车尾气污染水平和污染物的分布规律,本文以监测数据为基础,结合当地的具体气象特点,利用CALINE4模式,对国内平原地区的一段高速公路上机动车排放的污染物CO的浓度进行模拟,并将模拟结果和实测结果进行对比分析,结果表明CALINE4模式可以判断平原地区高速公路两侧机动车尾气CO污染状况,动态地估计平原地区高速公路环境交通容量,间接地评价该区域的空气质量。
為瞭研究我國平原地區高速公路兩側的機動車尾氣汙染水平和汙染物的分佈規律,本文以鑑測數據為基礎,結閤噹地的具體氣象特點,利用CALINE4模式,對國內平原地區的一段高速公路上機動車排放的汙染物CO的濃度進行模擬,併將模擬結果和實測結果進行對比分析,結果錶明CALINE4模式可以判斷平原地區高速公路兩側機動車尾氣CO汙染狀況,動態地估計平原地區高速公路環境交通容量,間接地評價該區域的空氣質量。

In order to research the motor vehicles exhaust pollution levels and distribution regularity of pol-lutants on both sides of the plain express way in China, based on monitoring data and combined with local meteorological characteristics to simulate the motor vehicle emissions of pollutants CO concentration on the section of china,s plain express way by using the CALINE4 model. Compared and analyzed the simulation results and measured results, the results indicate that CALINE4 model can be used to judge motor vehicle exhaust pollution status of CO on both sides of the plain express way and to estimate environment traffic ca-pacity of the plain express way dynamically and to assess the air quality of this area indirectly.
