• 中文摘要： 本文係調查北部高速公路附近之氣象因素，並以Gauss, Sutton等擴散模式，配合Pasquillstability categories推計高速公路兩旁之擴散情形。 依據測析結果，顯出通車後環境污染背景，較前已增加三至五倍，污染源高度約在二至四公尺，在公路兩旁二十至五十公尺易形成嚴重之污染帶，從公路兩旁五十公尺處，污染濃度則逐慚減少，這些結果均符合擴散模式。 為配合農業增產，在公路兩旁一百公尺地帶應設法栽培污染抗性較強之農作物。
• 英文摘要： According to Pasquill stability categ-ories and collected meteorological factors,we adopt the model of Gauss and Suttonto calculate the dispersion of pollutantsaround the northern free way. The observed value show that, com-paring with background, the contaminationincrease 3 to 5 times. The pollutantssource is 2 to 4 meters in height, so thatthe serious zone of contamination is formedby side of 20 to 50 meters from the freeway. And far from 50 meters, the cont-amination of air pollution are decreasinglittle by little. These results are in accordance withthe model of dispersion. So that we makean offer that both side of 100 metersaround free way may be suitable foranticontamination plants.
