生物标志化合物稳定碳同位素地球化学是80末期新兴的研究领域。单个生物标志化合物碳同位素组成的成因解释是该领域至关重要的问题。本文综合讨论了与此有关的生物合成过程中脂类化合物碳同位素变化、细菌生物合成过程中碳同位素分馏及其脂类化合物碳同位素组成特征，从而为我国的生物标志化合物碳同位素地球化学研究提供了新的理论依据。

In the late 1980’s stable carbon isotopic geochemistry of biomarker compounds appeared as a new field of scientific research. The original interpretation of carbon isotopic compositions of individual biomarker compounds is critical to the new field. This paper comprehensively discusses carbon isotopic variations of lipid compounds in the biosynthesis, carbon isotopic fractionations in bacterial biosynthesis and carbon isotopic compositions of bacterial lipid compounds, attemping to provide useful imformation for the research of carbon isotopic geochemistry of biomarker compounds. Studied results show that the carbon isotopic variations of individual organic compounds in the same type of lipids or between different types of lipids are apparent due to carbon isotopic fractionations in the biosynthesis. The process of bacterial biosynthesis have a larger carbon isotopic fractionation compared to that of other biosynthesis, therefore the bacterial lipid compounds are strongly depeted in ¹³C.
