| Research Abstract |
Fluxes of methane and water vapor were measured applying eddy covariance method over a lowland evergreen forest in the southeastern Asia under the tropical monsoon climate. In the rainy season, the diurnal variation of methane flux was not clearly observed, but the daily mean indicated the slight emission of methane from the forest ecosystem. In the dry season, the distinct methane absorption into the ecosystem was shown from the calculated flux in the daytime. For both seasons, the diurnal trends of methane flux were not corresponding to those of water vapor flux: The result suggested that the transpiration from the trees was not a motive force of methane emission, at least at the lowland evergreen forest.
