JapanFlux2024 TH-Mae Mae Moh plantation

The experiments were carried out in an even-aged teak (Tectona grandis Linn. f.) plantation located in the upper part of the Chao Phraya river basin, in Mae Mo district, Lampang Province, northern Thailand. Teak plantations have been widely established throughout the tropics, especially in Indochina and India, due to their high market value-a trend that is likely to continue in the foreseeable future. A case in point is Thailand, where significant decreases in forest area were documented until the 1980s. Forest rehabilitation and plantation have since been vigorously promoted, resulting in the establishment of large-scale teak plantations by the Forest Industry Organization, one of which is used here as a case study.The turbulent fluxes of sensible heat, latent heat, CO2 were measured using the eddy covariance system.本实验于泰国北部南邦府梅莫区湄南河上游流域的同龄柚木（Tectona grandis Linn. f.）人工林中开展。柚木因市场价值高昂，已在全球热带地区广泛营建人工林，尤其集中于中南半岛与印度，该发展趋势在可预见的未来仍将延续。以泰国为例，该国直至20世纪80年代仍存在森林面积显著缩减的情况，此后当地大力推动森林修复与人工造林工作，由林业产业组织（Forest Industry Organization）建成了大规模柚木人工林，本研究选取其中一处作为案例研究对象。本研究采用涡度协方差系统（eddy covariance system）对感热通量、潜热通量与二氧化碳（CO₂）的湍流通量进行了测定。
