英文摘要	We report the first extensive study of the spatial distribution and source apportionment of aliphatic hydrocarbons in soils from the Beijing outskirts. Mixed soil samples (5-30 cm depth) were collected for the quantitative determination of n-alkanes, isoprenoids, unresolved complex mixtures and the qualitative determination of hopanes and steranes. The total concentrations, including n-alkanes from C-13 to C-36, pristane and phytane, were in the range of 0.60-39.92 mug/ g, with a median value of 1.97 mug/g. No correlation between soil organic matter content or the percentage of clay and the concentrations was found. Carbon preference index (CPI) values for the whole range of n-alkanes varied between 0.73 and 4.27, with a median value of 1.64, and a contour map of CPI was drawn. A predominance of odd/even carbon n-alkanes and unresolved complex mixtures with different shapes and range were frequently observed. Factor analysis reduced the data set to two principal components explaining 82.82% of the total variation among samples and confirming contributions from low molecular weight species (63.66%) and long-chain n-alkanes (19.27%), respectively. Based on the principal component analysis, the concentration profiles and molecular markers, it was concluded that the aliphatic hydrocarbons were from both biogenic and anthropogenic sources.
