英文摘要	Aerosol absorption coefficient ap involves the additive contribution of both black carbon aerosol(BC)and dust aerosol.The linear statistical regression analysis approach introduced by Fialho et al.(2005)is used to estimate the absorption exponents of BC and dust aerosol absorption coefficients,and further to separate the contributions of these two types of aerosols from the total light absorption coefficient measured in the hinterland of Taklimakan Desert in the spring of 2006.Absorption coefficients are measured by means of a 7-wavelength Aethalometer from 1 March to 31 May and from 1 November to 28 December,2006. The absorption exponent of BC absorption coefficient alpha is estimated as(-0.950.002)under background weather(supposing the observed absorption coefficient is due only to BC);the estimated absorption exponent of dust aerosol absorption coefficient beta during the 6 dust storm periods(strong dust storm)is (-2.550.009).Decoupling analysis of the measured light absorption coefficients demonstrates that,on average,the light absorptions caused by dust aerosol and BC make up about 50.5%and 49.5%respectively of the total light absorption at 520 nm;during dust weather process periods(dust storm,floating dust, blowing dust),the contribution of dust aerosol to absorption extinction is 60.6%on average;in the hinterland of desert in spring,dust aerosol is also the major contributor to the total aerosol light absorption, more than that of black carbon aerosol.
