Origins of n-alkanes in surface soil from permafrost regions in the northern part of the Tibetan Plateau were studied by the distributions of n-alkanes, and the δD values of individual n-alkanes. That the distributions of the n-alkanes showed bimodal and trimodal patterns, suggesting that they were derived from multiple sources. The long-chain n-alkanes were mainly derived from higher terrestrial plants. Those of odd carbon number (C25~C33) were lighter than those with even carbon number, which might be caused by different biosynthetic pathways. Cluster analysis indicated that the medium-chain type I n-alkanes (C21~C24) were mainly derived from higher terrestrial plants, and the medium-chain type Ⅱ n-alkanes might have originated from microorganisms such as bacteria. The medium-chain n-alkane δD values of samples FHS-10, TG2-10and TG3-10were the lightest, due to both the light δD values of water and bacteria or other microorganisms.
