Characterization of Alpine peatlands based on remote sensing of vegetation and water content

2021
<p>Storing up to 70 kg of carbon per cubic meter, peatlands are among the most carbon-dense environments in the world. If in pristine conditions, peatlands support a number of ecosystem services as for example water retention and mitigation of droughts and floods, water purification, water availability to wildlife.

Organic Carbon Flux in Ditches during the Growing Season in a Drained Alpine Peatland

Ecohydrology, 2019
AbstractThe carbon budget dynamics of peatlands plays a crucial role in both the response of peatland ecosystems to environmental change and the effect of environmental change on peatlands. Studies on northern peatlands have suggested that the reliable assessment of the carbon budget must include the carbon flux at the land‐stream interface.

A multi-sensor approach to the study of geomorphic, vegetation and hydrogeologic patterns of Alpine peatlands

2023
Geomorphic and vegetation patterns within peatlands are strictly related, and reflect the interactions among topography, hydrogeology, and climate. Vegetation patterns are closely related to soil moisture, drainage patterns, bulk density and carbon content, and the spatial distribution of different plant species as well as the spatial variability of ...

The Primary Drivers of Greenhouse Gas Emissions Along the Water Table Gradient in the Zoige Alpine Peatland

Water, Air, and Soil Pollution, 2020
Zoige alpine peatland as the highest and largest peat swamp area in the world plays an important role in regulating global climate change and stabilizing GHG emissions, and GHG emissions are getting more and more concern due to water table decline induced by the combined effects of climate warming and digging ditches in Zoige alpine peatland. Therefore,

Annual ecosystem respiration variability of alpine peatland on the eastern Qinghai–Tibet Plateau and its controlling factors

Environmental Monitoring and Assessment, 2015
Peatlands are widely developed in the eastern Qinghai-Tibet Plateau, but little is known about carbon budgets for these alpine peatland ecosystems. In this study, we used an automatic chamber system to measure ecosystem respiration in the Hongyuan peatland, which is located in the eastern Qinghai-Tibet Plateau. Annual ecosystem respiration measurements

Glacial Preconditioning of Alpine Peatland Formation

Peatlands are ecosystems that comprise the largest terrestrial carbon store on Earth. They play a critical role in climate change mitigation, while also supporting unique biodiversity, regulating water flow and serving as paleoecological archives.

Ionic regulation in an alpine peatland in the Bogong High Plains, Victoria, Australia

Environmental Chemistry, 2009
Environmental context. Australian alpine peatlands are thought to have an important role in maintaining water quality in the associated headwater streams. This study has confirmed that these peatlands can significantly modify stream water through a range of mechanisms, including: nutrient uptake, salt sequestering, and the export of organic carbon ...

The carbon stock of alpine peatlands on the Qinghai–Tibetan Plateau during the Holocene and their future fate

Quaternary Science Reviews, 2014
Most studies about carbon dynamics of peatlands have been focused on boreal, subarctic and tropical peatlands. However, there is limited data about carbon dynamics of alpine peatlands, like Zoige peatlands on the Qinghai-Tibetan Plateau (QTP), which are sensitive to climate change and human disturbance. We studied the role of these peat deposits on the

Accumulation of organic carbon over the past 200 years in alpine peatlands, northeast China

Environmental Earth Sciences, 2014
Peatlands are widely distributed throughout northeast China and form a large carbon (C) pool. The main types include plain wetlands and alpine peatlands. Compared to the former, the historical development and C dynamics of the alpine peatlands are still not well understood.

Carbon emission flux and storage in the degraded peatlands of the Zoige alpine area in the Qinghai–Tibetan Plateau

Soil Use and Management, 2020
Abstract The Zoige alpine peatlands cover approximately 4,605 km 2 of the Qinghai–Tibetan Plateau and are considered to constitute the largest plateau peatland on the Eurasian continent.
