Abstract: Micrometeorological methods and enclosures/chamber methods for estimating the forest CO2 flux were introduced in this paper. Eddy covariance method, relaxed eddy accumulation method, energy balance method and aerodynamic method were introduced in the micrometeorological methods. In case of enclosures/chamber methods, the principles of this method and data modeling analysis were given. Finally, the research advances on forest CO2 flux estimation in Europe and America were proposed.
