Asian terrestrial ecosystems occupy vast areas from tropical forests and wetlands in Southeast Asia to boreal ecosystems in northeastern Asia, and as well as alpine ecosystems on the Tibet Plateau. These ecosystems make a significant contribution to the regional and global carbon budgets. Accurately quantifying CO/CH balances is critical for setting targets for their emission reductions and to identify and promote effective mitigation strategies. Since the mid-1990s, we have been installing multichannel automated chamber systems boreal ecosystems in Siberian and Alaska, temperate forests and grassland in East Asia, wetlands and permafrost on the Tibetan Plateau, and subtropical and tropical forests in Southeast Asia, for continuous measurements of forest floor CO budget as well as net ecosystem production. Among the sites, eight ecosystems are using for conducting soil warming experiments. This talk will present CO/CH fluxes and their controls of representative Asian terrestrial ecosystems with the chamber network.
