Divergent shift of normal alpine meadow exacerbated soil loss of hillslope alpine meadows based on field experiments

International Soil and Water Conservation Research
Global climate change and overgrazing are driving shifts in the plant composition of grassland communities, which may profoundly affect the function of grassland ecosystems in regulating runoff and soil erosion.

THE DYNAMICAL BEHAVIOR AND APPLICATION OF ONE ALPINE MEADOW MODEL

Journal of Applied Analysis & Computation, 2021
Summary: In recent years, the alpine meadow has degraded seriously, before restoring the degraded alpine meadow, it is necessary to know the cause of degrading and to find the effective restoration measure. One forage grass-livestock-rodent-raptor dynamical model is formulated and analyzed.

Characterization of the spatial distribution of plateau pika burrows along an alpine grassland degradation gradient on the Qinghai–Tibet Plateau

Ecology and Evolution, 2021
Plateau pika burrows are common feature of degraded grassland in the Qinghai–Tibet Plateau (QTP) and serve as an important indicator of pika activity and grassland degradation.

Influences of drought on the stability of an alpine meadow ecosystem

Ecosystem Health and Sustainability, 2022
ABSTRACT Drought plays a prominent role in affecting ecosystem stability and ecosystem productivity. Based on eddy covariance and climatic observations during 2012–2020, the Fisher discriminant analysis method was employed to accurately detect drought occurrences. Furthermore, the ecosystem water sensitivity and its resistance to

Methane emission by plant communities in an alpine meadow on the Qinghai-Tibetan Plateau: a new experimental study of alpine meadows and oat pasture [PDF]

Biology Letters, 2009
Recently, plant-derived methane (CH 4 ) emission has been questioned because limited evidence of the chemical mechanism has been identified to account for the process. We conducted an experiment with four treatments (i.e.

Precipitation Alters the Effects of Temperature on the Ecosystem Multifunctionality in Alpine Meadows. [PDF]

Front Plant Sci, 2021
Precipitation and temperature are major controls on multiple ecosystem functions in alpine grasslands. There is scant evidence for the interactive effects of temperature and precipitation changes on the ecosystem multifunctionality (EMF) in alpine meadows.

Seasonal Variation in Soil and Herbage CO2 Efflux for a Sheep-Grazed Alpine Meadow on the North-East Qinghai-Tibetan Plateau and Estimated Net Annual CO2 Exchange

Frontiers in Plant Science, 2022
The Qinghai-Tibetan Plateau is a vast geographic area currently subject to climate warming. Improved knowledge of the CO2 respiration dynamics of the Plateau alpine meadows and of the impact of grazing on CO2 fluxes is highly desirable.
