Advances in carbon flux observation and research in Asia

摘要: As an important component of FLUXNET, Asia is increasingly becoming the hotspot in global carbon research for its vast territory, complex climate type and vegetation diversity. The present three regional flux observation networks (i.e. AsiaFlux, KoFlux ChinaFLUX) have 54 sites altogether, covering tropic rainforest, evergreen broad-leaved forest, coniferous mixed shrubland, grassland, alpine meadow cropland ecosystems with a latitudinal distribution from 2°N to 63°N. Long-term continuous fluxes dioxide, water vapor energy between biosphere atmosphere are mainly measured eddy covariance technique (1) quantify compare carbon, budgets across diverse ecosystems; (2) environmental biotic controlling mechanism on ecosystem fluxes; (3) validate soil-vegetation-atmosphere model; (4) serve integrated study terrestrial cycle. Over last decades, great advancements been made theory technology measurement, patterns, simulation scale conversion by Asian community. establishment ChinaFLUX has greatly filled gap Eurasia. To further promote measurement research, accelerate data sharing improve quality, it necessary methodological system estimation evaluation over terrain develop that combines stable isotope remote sensing GIS technique. It also requires Joint Committee Flux Network Asia-Pacific region order cooperation communication ideas supporting project scientists, workshops visiting scientists.
