This study respective using the exponential equation and double exponential equation which are widely used were fitted Pinus massoniana, evergreen broad leaved forest, deciduous oak forest, pine-oak forest, Pinus koraiensis and Pinus tabulaeformis and other six kinds of typical natural forest soil organic carbon mineralization process, it also by fitting curves and cumulative release of CO2mineralization process analysis and correlation of inert carbon content of soil measured and fitted values of t-test analysis, the two exponential equations in natural forest soil organic carbon mineralization process the application results were evaluated. The results show that the double exponential equation on soil organic carbon mineralization has a better fitting description effect can be more realistically reflect the changes in soil organic carbon mineralization characteristics of the fitting results of insert soil carbon content and measured values a significant difference is not level, the soil can be more accurately reflect the changes of the inert carbon.
