Above- and below-ground response to soil water change in an alpine wetland ecosystem on the Qinghai-Tibetan Plateau, China

open access: yesJournal of Hydrology, 2013
The reduction of soil water content induced by global warming is expected to affect plant communities worldwide. However, less is known about the consequences of global warming-induced decreases of soil water on alpine wetland ecosystems on the Qinghai ...

Feedbacks of Alpine Wetlands on the Tibetan Plateau to the Atmosphere

Wetlands, 2019
The alpine wetlands of the Tibetan Plateau (TP) contribute 30%–40% of China’s natural wetlands, and they are experiencing changes in climate, i.e. warming of 0.26 °C 10 yr−1 (since the 1950s), as well as considerable human impacts. Consequently, alpine wetland extent show strong response to these impacts in most part, a reduction since the 1970s ...

Fluxes of methane, carbon dioxide and nitrous oxide in an alpine wetland and an alpine grassland of the Tianshan Mountains, China [PDF]

open access: yesJournal of Arid Land, 2014
Methane (CH4), carbon dioxide (CO2) and nitrous oxide (N2O) are known to be major greenhouse gases that contribute to global warming. To identify the flux dynamics of these greenhouse gases is, therefore, of great significance. In this paper, we conducted a comparative study on an alpine grassland and alpine wetland at the Bayinbuluk Grassland Eco ...

Water chemistry and periphyton in an alpine wetland

Hydrobiologia, 1995
Remote high elevation sites are thought to be good sites to monitor global change and anthropogenic effects on ecosystems. This study was conducted during 1987–1990 in a high elevation wetland (3593 m) located in the Green Lakes Valley, Front Range, Colorado (USA). Salix spp. was the dominant riparian species in this 2 ha. wetland. Small shallow pools (

Changes in alpine wetland ecosystems of the Qinghai–Tibetan plateau from 1967 to 2004 [PDF]

open access: yesEnvironmental Monitoring and Assessment, 2010
Spatiotemporal shifts in the extent and distribution of alpine wetland ecosystems in China's Qinghai-Tibet plateau were investigated for the period 1967-2004. Using aerial photographs for 1967, and satellite remote sensing data for 1986, 2000, and 2004/5, the main components and distribution of alpine wetland ecosystems in the headwaters regions of the

Spectral features and separability of alpine wetland grass species

Spectroscopy Letters, 2016
ABSTRACTThis study aimed to analyze the spectral features of alpine wetland grasses and evaluate three types of spectral feature computational methods. In situ spectra of alpine wetland grasses were collected in the northeastern Qinghai–Tibetan Plateau (Niaodao Wetland of International Importance and Ruoergai Wetland of International Importance), and ...

Long‐term degradation from marshes into meadows shifts microbial functional diversity of soil phosphorus cycling in an alpine wetland of the Tibetan Plateau

Land Degradation and Development, 2021
Soil microbes greatly contribute to the regulating of phosphorus (P) cycling, which plays a significant role in maintaining wetland ecosystem processes and function. The microbial functional diversity of soil P cycling in response to wetland degradation,

Morphological plasticity of Primula nutans to hummock-and-hollow microsites in an alpine wetland

Journal of Plant Research, 2006
Hummock-and-hollow microtopography is common in wetlands of the Qinghai-Tibetan Plateau. The physical environment of hummocks contrasts strongly with that of hollows. To address how Primula nutans Georgi, a herbaceous species broadly distributed on the plateau, can inhabit both hummocks and hollows, we investigated the plasticity of its morphology and ...

Analysis of fungal community structure in the soil of Zoige Alpine Wetland

Acta Ecologica Sinica, 2009
Abstract To understand the soil fungal community diversity in different zones of the Zoige Alpine Wetland, BIOLOG analysis and traditional culture method were employed in our research. Three sample sites namely the Conservatory Station up-hill slope (CSUS), the Flower Lake side (FLS) and the Conservatory Station down slope (CSDS) with increasing by ...
