Tropical rainforests are the largest carbon pool in the terrestrial environment of the planet. These ecosystems are mainly distributed in the Amazon Basin (South America), the Congo Basin (Africa), and Southeast Asia and Melanesia. The most precious sub-regions are humid forests where receiving more than 2000 mm of precipitation annually. Plants in these areas can grow with minimum amount of environmental stress and harbor a substantial amount of endemic species, where are recognized as the global biodiversity hotspots. The impact of global change on the tropical humid forests under the era of Anthropocene has been pronounced, especially for carbon sequestration. In the recent decades, due to industrial logging and oil palm plantation, rainforests of Southeast Asia have suffered the most severe anthropogenic perturbations globally. Surprisingly, the knowledge we have to this vast region has been sparse. Therefore, in this half-year project, I will utilize a large amount of satellite imagery to investigate the dynamics of forest net primary productivity in the past two decades and its relationship with climate. In addition, with the knowledge of climate prediction and environmental plant physiology, I might to able to delineate the future carbon budget of Southeast Asia humid forests.大氣環流模式全球暖化土地使用改變油棕植物生理學遙測General circulation modelglobal warmingland use and land cover changeoil palmplant physiologyremote sensing
