Fluxes of CH4 from de-farming grasslands,bushes,pinus massoniana forests and hardwood forests which are located at central Guizhou were measured in si-tu using static closed chamber technique between 2006 and 2007.The results indicated that subtropical karst non-agricultural soils were the important sinks of atmospheric CH4.Under the same vegetation,CH4 fluxes from lime alfisol were lager than those from yellow soil.However,the fluxes of CH4 from soils under different vegetations varied with soil type.The g...
