| 摘 要： | 利用 2 0 0 0年兰州市大气污染源调查资料 ,对影响该市的主要大气污染物的年分担率进行 1 km× 1 km 网格分析 ,结果表明 :由生活源排放的主要大气污染物年分担率呈“面”状联片分布 ,年分担率并不高 ,但影响范围较大 ;而工业源年分担率呈“点”状分散分布 ,年分担率较大 ,网格内影响较严重 ;叠加源呈“区域”壮大范围联片分布 ,年分担率最大 ,影响的范围也广 ,污染物年分担率的分布正好与污染源的位置分布相一致 ,高值区与排放量较大的污染源相对应。

| Abstract: | By using of investigation data of air pollution source of Lanzhou city in 2000 ,were analyzed by grid of the year share percentage of the chief air pollution source and air pollutant 1km×1km .The result showed that the share percentage of residential sources like “surface of discontinuity”, being not higher,but area of coverage being more wider,and the share percentage of industrial sources like“dot of discontinuity”, being higher,area of coverage being not wider,while the superimposed source like“area of continuity”,and the share percentage was higher,but area of coverage was the most wide,and that the year share percentage of air pollutant was closely relatied to sources location. |
