利用PMF模型和PCA/APCS模型对南京北郊大气VOCs进行定性和定量的源解析,并对比两种模型的结果。结果表明:PMF模型对不同VOCs种类的模拟效果差别较大,而PCA/APCS对不同VOCs种类的模拟效果相近;PMF模型解析的源个数多于PCA/APCS模型,两种模型解析的源性质方面存在较大相似性,但PCA/APCS模型未能区分汽油挥发和汽车尾气源;两种模型源解析的植物排放源、工业生产源的贡献率较接近,而其他源的贡献率存在差异,PCA/APCS模型解析的溶剂使用源的贡献率高于PMF模型,PMF模型解析的汽油挥发+汽车尾气源的贡献率高于PCA/APCS模型。
利用PMF模型和PCA/APCS模型對南京北郊大氣VOCs進行定性和定量的源解析,併對比兩種模型的結果。結果錶明:PMF模型對不同VOCs種類的模擬效果差彆較大,而PCA/APCS對不同VOCs種類的模擬效果相近;PMF模型解析的源箇數多于PCA/APCS模型,兩種模型解析的源性質方麵存在較大相似性,但PCA/APCS模型未能區分汽油揮髮和汽車尾氣源;兩種模型源解析的植物排放源、工業生產源的貢獻率較接近,而其他源的貢獻率存在差異,PCA/APCS模型解析的溶劑使用源的貢獻率高于PMF模型,PMF模型解析的汽油揮髮+汽車尾氣源的貢獻率高于PCA/APCS模型。

The PMF model and PCA/APCS model were used to apportion atmospheric VOCs qualitatively and quantitatively in Nanjing,and both results were compared.The results show that the simulation result for the differ-ent types′VOCs by the PMF model significantly differs,while it is similar to each other by the PCA/APCS mod-el.The number of sources apportioned by the PMF model is greater than that by the PCA/APCS model.Both source profiles are similar,while the PCA/APCS model fails to distinguish gasoline evaporation and vehicle ex-haust emission.The contributions of plant emission and industrial production apportioned by the two models are close,while those of the other sources differ.The contribution of solvent use is greater for the PCA/APCS model than for the PMF model,while the contribution of gasoline evaporation plus vehicle exhaust is greater for the PMF model than for the PCA/APCS.
