英文摘要: Lipids extracted from 26 modern soils collected from different climate zones in China and Mongolia are analyzed using gas chromatography-mass spectrometry. These extracts contain-pseudohomologous families of 5,5-diethylalkanes (5,5DEAs), 6,6-diethylalkanes, 5-butyl-5-ethylalkanes and 6-butyl-6-ethylalkanes, which are first detected in modern soils. All these pseudohomologous series display exclusively odd or exclusively even carbon numbers, clearly indicating a biosynthetic origin, and their carbon number distributions generally covary. The distributions of 5,5-DEAs exhibit strong regional variations, correlated with the spatial distributions of climate and vegetation. The lower molecular weight 5,5-DEAs, maximizing at C-21 or C-23, dominate in southeast and southwest China samples, while the higher molecular weight 5,5-DEAs with a mode at C-29 dominate in cold, and northwest China and Mongolia. The results demonstrate that the distribution of 5,5-DEAs can serve as a new independent proxy, indicating variations in soil ecosystems and climates, just like the well-known proxy of n-C15-21/n-C22-33 ratios.
