CH_4 oxidation,which is affected by many factors, is the natural regulation of CH_4 concentration in the atmosphere. Vegetation can change the soil physiochemical properties through various processes, and consequently influences the CH_4 oxidation potential. Undoubtedly, the terrain ecosystem is always comprised of different vegetation types. Therefore, study of the CH_4 oxidation potential and stable carbon isotope fractionation of soils under different vegetation types, are crucial for improving our knowledge in the mechanisms of soil CH_4 oxidation and carbon emission accounting. In this study, soils in six typical vegetation types, including primary forest, coniferous forest, conifer-broadleaf forest, evergreen broad-leaved forest, grass land and rice field were collected, for investigating the soil CH_4 oxidation potential (Psi_(ox)) and stable carbon isotope fractionation (alpha_(ox)) and their affecting factors. Results showed that the Psi_(ox) differed obviously among different vegetation types. The order for Psi_(ox) was rice field (10.75)>coniferous forest (4.39)>primary forest (3.83)>evergreen broad-leaved forest (3.21)>conifer-broadleaf forest (1.78)>grass land (0.95) (mug·g~(-1)·d~(-1)). Statistical analysis showed that the Psi_(ox) was positively correlated to NO_3~--N (r=0.93, P=0.006) and DOC (r=0.96, P=0.002) ,TC (r=0.46, P=0.356), TN (r=0.74, P=0.093), NH_4~+-N (r=0.47, P=0.344) and negatively correlated to pH (r=-0.51, P=0.298), indicating that the soil carbon and nitrogen could promote while the pH could inhibit methane oxidation in these soils. Meanwhile, the alpha_(ox) for the soils in rice field, primary forest, coniferous forest, conifer-broadleaf forest, evergreen broad-leaved forest and grass land was 1.022, 1.017, 1.013, 1.012, 1.015 and 1.012. Moreover, soil alpha_(ox) was positively and significantly correlated to Psi_(ox) (r=0.92, P=0.01). These would be due to the methane affinity of the soil methanotrophs. Being affected by Psi_(ox), the correlations between alpha_(ox) and soil properties were similar to those between Psi_(ox) and soil properties.
