Ecological Risk Assessment and Impact Factor Analysis of Alpine Wetland Ecosystem Based on LUCC and Boosted Regression Tree on the Zoige Plateau, China

Remote Sensing, 2020
The Zoige Plateau is typical of alpine wetland ecosystems worldwide, which play a key role in regulating global climate and ecological balance. Due to the influence of global climate change and intense human activities, the stability and sustainability ...

Does wetland degradation impact bird diversity differently across seasons? A case study of Zoige Alpine Wetland ecosystem

Avian Research, 2023
Wetland degradation is an escalating global challenge with profound impacts on animal diversity, particularly during successional processes. Birds, as highly mobile and environmentally sensitive organisms, serve as effective indicators of ecological change.

The Aridity Threshold of Soil Organic Carbon Density Along the Climate Aridity Gradient in the Alpine Ecosystem of the Qinghai‐Tibetan Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil organic carbon density (SOCD) is a key indicator for evaluating the stability of soil carbon pools, especially in alpine ecosystems that are sensitive to climate change. However, research on the response of SOCD to different aridity gradients is still limited. Therefore, we conducted extensive sampling along different aridity gradients of

Iron-mediated soil carbon response to water-table decline in an alpine wetland [PDF]

Nature Communications, 2017
AbstractThe tremendous reservoir of soil organic carbon (SOC) in wetlands is being threatened by water-table decline (WTD) globally. However, the SOC response to WTD remains highly uncertain. Here we examine the under-investigated role of iron (Fe) in mediating soil enzyme activity and lignin stabilization in a mesocosm WTD experiment in an alpine ...

Significant Imbalance Between Human Activities and Ecosystem Services in the Tibet Autonomous Region of China: Evidence From an Improved Coupling Coordination Degree Model

Land Degradation &Development, EarlyView.
ABSTRACT Maintaining balanced interactions between humans and ecosystems in plateau regions is critical to achieving global sustainable development. However, existing methodologies are insufficient to fully elucidate the complex coupling and coordination relationships between human activities and ecosystems, as well as the sustainable development ...

Variability and Changes in Climate, Phenology, and Gross Primary Production of an Alpine Wetland Ecosystem [PDF]

Remote Sensing, 2016
Quantifying the variability and changes in phenology and gross primary production (GPP) of alpine wetlands in the Qinghai–Tibetan Plateau under climate change is essential for assessing carbon (C) balance dynamics at regional and global scales. In this study, in situ eddy covariance (EC) flux tower observations and remote sensing data were integrated ...

Response of Soil Fungal Communities to the Alpine Steppe Degradation Gradient

Land Degradation &Development, EarlyView.
ABSTRACT The degradation of alpine steppe on the Qinghai‐Tibet Plateau has become a critical ecological security issue. Soil fungi, as core regulators of grassland ecosystem functioning, play a pivotal role in mediating the feedback between degradation and soil ecological processes.

Multi‐Scale Pathways to Integrated Protection and Restoration of Mountains, Rivers, Forests, Farmlands, Lakes, and Grasslands in the Three Gorges Reservoir Area: A Social‐Ecological Systems Perspective

Land Degradation &Development, EarlyView.
ABSTRACT Human activities have intensified eco‐environmental problems, challenging harmonious human‐nature interactions. However, existing integrated protection and restoration (IPR) zoning approaches for mountains, rivers, forests, farmlands, lakes, and grasslands (MRFFLG) focus on a single scale and fail to incorporate the ecological network (EN) and

Characteristics of water dissolved organic matter in Zoige alpine wetlands, China

Chemical and Biological Technologies in Agriculture
Background Dissolved organic matter (DOM) plays a significant role in the biogeochemical cycle of crucial elements in aquatic ecosystem. However, it is still not clear on the spectral characteristics of water DOM in different types of alpine wetlands ...
