Abstract: Alpine meadow is one of the main vegetation types in the Qinghai-Tibet Plateau. Alpine meadows are variably degraded under the influence of climate change and human activities. The carbon flux in alpine meadows changes with the degradation. However, the characteristics of carbon flux components during degradation in alpine meadows are still unclear,hindering our understanding of the transition between carbon sink and source in responding to global changes. In this study,four degradation degrees ... More
