fluxes of alpine meadow ecosystems on the Tibetan Plateau

Alpine meadow is the key vegetation widely distributed on the Tibetan Plateau. Alpine ecosystem is a great important part in biogeochemical cycle between air and the ground surface, and it plays an extremely important role in carbon balance in this area. Advances on CO2 fluxes of alpine ecosystem were reviewed. The variations of carbon dioxide fluxes of alpine meadow ecosystem and its effecting factors were summarized on the Tibetan Plateau. Furthermore, the potential of source/sink and value of Q10 were compared between typical alpine meadow ecosystems and others. More specifically, some unsolved questions which need to be answered in the future were raised in this review.
