Abstract
The soil -air exchange processes of CH$_4$ were investigated in Hari district of Kang Hwa Island, Korea during the late April 2002. In the course of our field experiments, we measured the concentration, concentration gradients (between two different heights of 1 and 5 m), and the fluxes of CH$_4$ using the surface layer gradient microm-eteorological methods. If the relationships between CH$_4$ fluxes and the relevant environmental parameters are examined, CH$_4$ fluxes were found to be affected most significantly by parameters like wind speed. The results of our study indicate that the study area behaved as a net source of CH$_4$ to the atmosphere with a net daily emission rate of 3.6 mg m￣$^2$ The findings of relatively low exchange rate observed at our study site suggest that the rice paddy area investigated prior to planting period can behave as a moderate source of methane.
