| 摘 要： | 运用因子分析法对成都城区近地表大气尘(NGD)的来源进行了解析,得到的主要排放源有:建筑尘、冶金尘、植物焚烧尘、煤烟尘(含土壤尘)、交通尾气尘、颜料涂料排放尘和城市垃圾尘。运用受体模型的化学质量平衡法对成都城区NGD的来源进行了解析,各排放源的贡献率分别是:土壤尘11.4%,建筑尘12.4%,煤烟尘5.8%,冶金尘11.2%,城市综合尘59.3%。

| Abstract: | The factor analysis method is applied for the sources apportionment of air dustfull near ground(NGD) in Chengdu Urban.The results show that there have seven main sources influencing NGD:(1) building soot,(2) steel and iron soot,(3) plant burning soot,(4) coal soot(contain soil soot),(5) traffic soot,(6) dyestuff and coating soot,(7) garbage soot.The pollution sources of NGD in Chengdu are analyzed by the chemical mass balance method based on receptor model.The average contribution rate of five pollution sources to NGD is that: soil soot is 11.4%,building soot is 12.4%,coal soot is 5.8%,steel and iron soot is 11.2%,synthetical soot of city is 59.3%. |
