| 摘 要： | 将成都市近地表大气尘通过多元统计的方法进行功能分区,可分为商业和居民生活区、三环路环带区域、东郊工业区、黄田坝和琉璃场工业区4个区域。源解析结果显示,商业和居民生活区的主要污染源是交通扬尘和城市生活垃圾尘;三环路环带区域近地表大气尘尘源是土壤风沙、燃煤、燃油和冶金;东郊的主要尘源是冶金和燃煤;黄田坝和琉璃场工业区近地表大气尘的主要排放源是冶金尘、污水和土壤。

| Abstract: | Through multivariate statistical analysis method,the air dust near the ground from Chengdu is divided into four zones:commercial and living area,area along the third circle,industrial area in east suburb,the industrial areas in Huangtianba and Liulichang.The results of source apportionment indicate that the predominant sources of the commercial and living area are dust from road and urban house refuse;the main sources of dust in the area along the third circle are soil,sand,ashes of coal,fuel and metallurgy;in the industrial area in east suburb,the main dust are from metallurgy and ashes of coal;and the dust in the industrial areas in Huangtianba and Liulichang are from metallurgy and soil. |
