The alpine meadow ecosystem is one of the major vegetation biomes on the Qinghai–Tibetan Plateau, which hold substantial quantities of soil organic carbon. Pronounced grassland degradations (induced by overgrazing/climate change and further exacerbated by the subterranean rodent activities) that have widely occurred in this ecosystem may significantly alter the non-growing season carbon turnover processes such as carbon dioxide (CO2) efflux, but little is known about how the non-growing season… Expand
Restoration efficiency of short-term grazing exclusion is the highest at the stage shifting from light to moderate degradation at Zoige, Tibetan Plateau
Abstract Grassland degradation has profound negative impacts on ecological functions, local economic development, and social stability. Although there are many studies on the alpine grasslandExpand
Characteristics of annual greenhouse gas flux and NO release from alpine meadow and forest on the eastern Tibetan Plateau
Abstract The importance of the world’s largest plateau (i.e., the Tibetan Plateau) as a source/sink for atmospheric greenhouse gases (GHGs) still remains uncertain as field observations coveringExpand
Annual methane emissions from degraded alpine wetlands in the eastern Tibetan Plateau.
TLDR
Degradation of the native peat marshes in the Zoige region (originally the largest area of alpine wetlands) due to intentional drainage has greatly reduced the quantities of CH4 emissions. Expand
Enhancing sustainability of grassland ecosystems through ecological restoration and grazing management in an era of climate change on Qinghai-Tibetan Plateau
Abstract The grassland ecosystems cover above 60% of Qinghai-Tibetan Plateau (QTP) and provide important ecosystem services and functions at local and regional scales. However, both anthropogenic andExpand

Litter affects CO2 emission from alpine wetland soils experiencing drying-rewetting cycles with different intensities and frequencies
Abstract The frequency and intensity of drying-rewetting cycles can influence soil CO2 emission from the soil and carbon (C) and nitrogen (N) in the soil, but little is known about whether suchExpand

Methane emissions in grazing systems in grassland regions of China: A synthesis.
TLDR
A synthesis of 43 individual studies was carried out to assess the grazing season/annual CH4 budgets and their responses to grazing in grassland ecosystems of China and demonstrate that mediating grazing intensity could yield the optimal balance between maintaining productive grasslands and meanwhile mitigating CH4 emissions.
