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 play important roles in regional and global carbon sink and global warming mitigation. 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 developing an automated chamber network that covers the 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 and wetlands in Southeast Asia, for continuous measurements of CO/CH budget as well as net ecosystem production. Among the sites, ten forests are using for conducting soil warming experiments. This talk will present long-term CO/CH fluxes and their response and feedback to climate change.
