Research Abstract |
This research evaluated the function of a Southeast Asian tropical rainforest as the sunk/source of several greenhouse gases. We mainly focused on the flux observation of the gas exchange of CO_2, H_2O, CH_4, N_2O, and BVOC at the scale of leaf, plant, soil, and also at the scale of whole canopy. We also tested the two kinds of expectative gas exchange indexes, i. e., the vegetation indexes using spectroradiometric observations, and indexes using stable isotopes. In this forest, variability in rainfall pattern resulted in seasonal and inter-annual variability in micrometeorology ; evapotranspiration, photosynthesis, and ecosystem respiration responded to these changes, and compensated for each other and/or other components of micrometeorology, resulting in rather stable annual evapotranspiration and NEE, even during a considerably dry year.
