Other Abstract

As two very important ecosystems on the Plateau, swamp and alpine meadows have been playing an important role in carbon balance. Studies were carried on CO_2 fluxes from the two ecosystems with a close chamber-infrared spectrum technique in the Fenghuoshan area on the Tibetan Plateau., The results showed that the CO_2 fluxes were significantly different between the swamp meadow and alpine meadow ecosystems and between the different degenerate meadows, correspondingly. The CO_2 fluxes from the non-degradation swamp meadow were higher than those from the non-degradation alpine meadow by 65.1 to 80.3 percent; the CO_2 fluxes from the moderate degradation swamp meadow were higher than those from the corresponding degradation alpine meadow by 22.1 to 67.5 percent. In contrast, the CO_2 fluxes from the severe degradation alpine meadow were higher than those from the corresponding degradation swamp meadow by 14.3 to 29.5 percent. In the same high-cold ecosystem, the CO_2 fluxes from non-degradation swamp meadow were 1.12~1.69 times and 1.41~3.86 times higher than those from the moderate and severe degradation swamp meadows, respectively; the CO_2 fluxes from the severe degradation alpine meadow were 1.11~1.78 times and 1.04~1.79 times higher than those from the non-degradation and moderate degradation alpine meadows, respectively.
