THE DYNAMICAL BEHAVIOR AND APPLICATION OF ONE ALPINE MEADOW MODEL

open access: yesJournal 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.

Whole-soil warming shifts species composition without affecting diversity, biomass and productivity of the plant community in an alpine meadow

open access: yesFundamental Research, 2022
The structure and function of plant communities in alpine meadow ecosystems are potentially susceptible to climate warming. Here, we utilized a unique field manipulation experiment in an alpine meadow on the Qinghai-Tibetan Plateau and investigated the ...

Seasonal variations in carbon dioxide exchange in an alpine wetland meadow on the Qinghai-Tibetan Plateau [PDF]

open access: yesBiogeosciences, 2010
Alpine wetland meadow could functions as a carbon sink due to it high soil organic content and low decomposition. However, the magnitude and dynamics of carbon stock in alpine wetland ecosystems are not well quantified.

Influences of drought on the stability of an alpine meadow ecosystem

open access: yesEcosystem 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
