[Important factors controlling rates of N2O emission and CH4 oxidation from forest soil].

In this study, laboratory incubation experiments were conducted to determine the effect of pH, soil water content, temperature, NH4+ and NO3- on N2O emission and CH4 oxidation of mixed broad-leaved Korean pine forest soil. Results showed that there were significant correlations between N2O emission rate, CH4 oxidation rate and soil pH and temperature under certain lab conditions. Meanwhile, the significant positive correlation between N2O emission rate and CH4 oxidation rate was also observed. The results suggested temperature and pH could be the most important factors controlling the rates of N2O emission and CH4 oxidation of a forest soil under this experiment conditions.
