Different grassland managements significantly change carbon fluxes in an alpine meadow.

ABSTRACT: Alpine meadow plays vital roles in regional animal husbandry and the ecological environment. However, different grassland managements affect the structure and function of the alpine meadow. In this study, we selected three typical grassland managements including free grazing, enclosure, and artificial grass planting and conducted a field survey to study the effects of grassland managements on carbon fluxes in an alpine meadow. The carbon fluxes were observed by static chamber and environmental factors including vegetation and soil characteristics were measured simultaneously. Our results show that the alpine meadow was a CO₂ and CH₄ sink, and grassland managements had a significant effect on all CO₂ fluxes, including gross ecosystem production (GEP, P
