Micro-scale fragmentation of the alpine meadow landscape on the Qinghai-Tibet Plateau under external disturbances

, 2021
Detailed characterization of alpine meadow ecosystems using spatial metrics is important to understand the underlying processes of meadow degradation and to inform its proper management. The change in the fragmentation of the alpine meadow on the Qinghai-

Understanding Alpine Meadow Ecosystems

2016
This chapter introduces the alpine meadow and its distribution in the headwater region of the Yellow River, including subtypes of alpine meadow, species composition and productivity, soil types and their properties. Various views on causes of grassland degradation are summarized.

Water yield response to plant community conversion caused by vegetation degradation and improvement in an alpine meadow on the northeastern Tibetan Plateau.

Science of the Total Environment, 2022
Water provision is an important ecological function of alpine meadows on the Tibetan Plateau. Quantitative assessment of the effects of vegetation change induced by vegetation degradation and improvement on water yield (WY) in alpine meadows is urgent ...

Effects of warming and clipping on CH4 and N2O fluxes in an alpine meadow

Agricultural and Forest Meteorology, 2021
Methane (CH4) and nitrous oxide (N2O) are two greenhouse gases with much more warming potential than carbon dioxide (CO2). However, there have been less studies on their responses to climate warming and land use practices, such as hay harvest in ...

Nitrogen dynamics of alpine swamp meadows are less responsive to climate warming than that of alpine meadows

Science of The Total Environment
The freeze-thaw cycle mediates permafrost soil hydrothermal status, nitrogen (N) mineralization, and loss. Furthermore, it affects root development and competition among nitrophilic and other species, shaping the pattern of N distribution in alpine ecosystems.

The phytosociology of some alpine meadows in N.W. Himalayas

Vegetatio, 1971
Phytosociological studies of certain meadows occurring above the tree line in N.W. Himalayas have been made. A close relationship of the ground cover with moisture, the thickness of soil cover and the amount and retention period of snow has been observed.

Nitrogen deposition and carbon sequestration in alpine meadows

Biogeochemistry, 2004
Nitrogen deposition experiments were carried out in alpine meadow ecosystems in Qinghai-Xizang Plateau in China, in order to explore the contribution of nitrogen deposition to carbon sequestration in alpine meadows. Two methods were used in this respect. First, we used the allocation of 15 N tracer to soil and plant pools.

Grazing influences biomass production and protein content of alpine meadows

Science of The Total Environment, 2022
Alpine grasslands are essential for carbon sequestration and food supply for domestic and wild herbivores inhabiting mountainous areas worldwide. These biomes, however, are alternatively threatened by the abandonment of agricultural and livestock practices leading to a fast-growing shrubification process while other mountain grasslands are suffering ...

Resource islands of Salix cupularis facilitating seedling emergence of the companion herbs in the restoration process of desertified alpine meadow, the Tibetan Plateau.

Journal of Environmental Management, 2021
Salix cupularis is a common shrub for ecological restoration of the desertified alpine meadow on the Tibetan Plateau. However, the effect of S.

Plant community change mediated heterotrophic respiration increase explains soil organic carbon loss before moderate degradation of alpine meadow

Land Degradation and Development, 2021
Alpine meadows on the Qinghai‐Tibet Plateau (QTP) store a huge amount of plant and soil carbon (C). The degradation of the alpine meadow has led to a significant loss of soil organic C (SOC), which endangers its weak C sink.
