%X Methane (CH4) fluxes in wheat fields of the North China Plain were measured by closed chamber and GC techniques. The measured fluxes in the soil-plant systems through opaque chamber and transparent chamber were then compared. The results show obvious seasonal variations but insignificant diurnal variations in CH4 flux in the system. Wheat cover induces larger seasonal flux variation in the soil-plant system. Wheat and light increase soil-plant CH4 uptake. More importantly, however, transparent closed chamber proves the best CH4 flux measurement method in the field experiment.
