摘要
本文对兰州市区和郊区大气温度廓线进行了比较分析,结果说明城市热岛效应使低层大气中上部(200—600m)增温大于郊区,200m以下因污染物削弱了到达地面的太阳辐射,增温小于郊区。用白天兰州低层大气中部的增温和大气混浊度资料做相关统计,证实两者具有正相关关系。
Based on the comparison of temperature profiles of Polluted urban atmosphere in Lanzhou with those of rural atmosphere in Gaolan, the urban island effect and the influence of air pollutants on lower atmospheric layer at different altitudes were analysed. An analysis of regression was carried out with the data of temperature increment in middle lower atmosphere and lower atmospheric turbidity during daytime. A linear correlation was observed.
