Grazing Intensity Impacts on Carbon Sequestration in an Alpine Meadow on the Eastern Tibetan Plateau
Livestock grazing has the potential to substantially alter carbon (C) storage in grassland ecosystem. In this study, we evaluated the soil-plant system C (0-30cm) under three different grazing intensities by yaks (light: 1.2, moderate: 2.0, and heavy: 2.9 yaks/ha) in alpine meadow on the eastern Tibetan Plateau. Soil organic C at 0-30cm depth and total plant components C increased from light gr...
متن کاملLight-intensity grazing improves alpine meadow productivity and adaption to climate change on the Tibetan Plateau
To explore grazing effects on carbon fluxes in alpine meadow ecosystems, we used a paired eddy-covariance (EC) system to measure carbon fluxes in adjacent fenced (FM) and grazed (GM) meadows on the Tibetan plateau. Gross primary productivity (GPP) and ecosystem respiration (Re) were greater at GM than FM for the first two years of fencing. In the third year, the productivity at FM increased to ...
متن کاملGrassland Management with Emphasis on Grazing Behaviour
Investigations into the behavioural responses by ruminants to differences in their grazing environment have led to improved understanding of the grazing process. This has proved useful in developing management strategies which are not only sympathetic to the animals’ natural behaviour, but can improve the level and efficiency of resource use. The components of grazing behaviour considered are a...

متن کاملImpacts of grazing intensity on denitrification and N2O production in a semi-arid grassland ecosystem
N2O production from denitrification in soils contributes to the enhanced greenhouse effect and the destruction of the stratospheric ozone. Ungulate grazing affects denitrification and the production of N2O. The short-term effect of grazing on denitrification and N2O production has been examined in several grassland ecosystems. However, the effects of long-term grazing have rarely been studied. ...
