Carbon exchange between terrestrial ecosystem and atmosphere was the most important ecological process in global carbon cycle. Understanding the spatial pattern and its control factors of carbon exchange between terrestrial ecosystem and atmosphere in different regions can promote accurately predicting and evaluating terrestrial ecosystem carbon sink function and would be useful for ecosystem carbon sink/source management under climate change in the future. Eddy covariance was a micrometeorological technique that allows a non-invasive measurement of the exchange of CO2 between ecosystem and atmosphere. In this study, we integrated published data based on Eddy covariance technique from FLUXNET、ChinaFLUX、AsiaFlux network and analysed the spatial pattern and control factors of gross primary production (GPP), ecosystem respiration (Re), and net ecosystem production(NEP) in Asian monsoon region in order to provide theoretic principle for building evaluation system for global terrestrial ecosystem carbon exchange.
