英文摘要	Understanding the relationships between carbon; nitrogen, their stable isotopes delta C-13 and delta N-15, and soil stoichiometry may further our understanding of the regulatory mechanisms of the soil quality index on the equilibrium on isotopic fractionation. Four plantations of Zanthoxylum planispinum var. dintanensis (5-7, 10-12, 20-22 and 30-32 years) in the karst plateau gorge area, Guizhou Province, China, were selected to determine the variation characteristics and interactions between leaves, leaf litter, soil carbon (C), soil nitrogen (N) and their isotopes with plantation age, and to explore the relationship between soil stoichiometry and the isotopes delta C-13 and delta N-15. The results were as follows: (1) the delta C-13 in leaves, litter, and soil were -28.04 parts per thousand +/- 0.59 parts per thousand, -26.85 parts per thousand +/- 0.67 parts per thousand, and -19.39 parts per thousand +/- 1.37 parts per thousand, respectively. The contents of delta N-15 were 2.01 parts per thousand +/- 0.99 parts per thousand, 2.91 parts per thousand +/- 1.32 parts per thousand, and 3.29 parts per thousand +/- 0.69 parts per thousand, respectively. The contents of delta C-13 and delta N-15 were ranked in the order, soil > litter > leaf. (2) With increasing plantation age, the soil C-13 decreased; the leaf and the litter delta N-15 increased first then decreased, and the litter delta C-13 and the soil delta N-15 did not vary significantly. (3) The litter layer was positively correlated with soil delta C-13 and negatively correlated to delta N-15. (4) Redundancy analysis showed that the soil microbial biomass carbon (MBC) and the bacteria/fungi (BAC/FUN) were the dominant factors affecting the natural abundance of C and N isotopes
