摘要: CH4 and N2O exchange fluxes from or to soil resulted from land use change were measured and compared during 1999 to 2000. The effect of land use change on overall GHG effect was estimated in this study. The CH4 uptake rate were decrease about 52%-54%, N2O emission was increased 88%-125%, the overall GHG emissions increased 71% after the natural grassland conversion to farmland. The effect of farmland conversion to grassland on GHG emissions were measured too. The CH4 uptake rate was not changed after the conversion, but the N2O emission decreased a lot.
