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.

本研究评估了东南亚热带雨林作为几种温室气体的沉没源的功能。本文主要对CO_2、H_2O、CH_4、N_2O和BVOC在叶片、植物、土壤和全冠层尺度上的气体交换通量进行了观测。本文还对两种预期气体交换指数进行了测试，即利用光谱辐射观测的植被指数和利用稳定同位素的指数。在该森林中，降雨模式的变化导致了微气象的季节和年际变化；蒸散发、光合作用和生态系统呼吸响应这些变化，并相互补偿和/或微气象学的其他组成部分，导致相当稳定的年蒸散发和NEE，即使在相当干燥的年份。
