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 ...

Composition and diversity of soil microbial communities in the alpine wetland and alpine forest ecosystems on the Tibetan Plateau

Science of The Total Environment, 2020
While the composition and diversity of soil microbial communities play a central and essential role in biogeochemical cycling of nutrients, they are known to be shaped by the physical and chemical properties of soils and various environmental factors.

Spatial variations on methane emissions from Zoige alpine wetlands of Southwest China

Science of The Total Environment, 2009
This study was aimed to understand the spatial variation of CH(4) emissions from alpine wetlands in Southwest China on a field-scale in two phenological seasons, namely the peak growing season and the spring thaw. Methane emission rates were measured at 30 plots, which included three kinds of environmental types: dry hummock, Carex muliensis and ...

Annual methane emissions from degraded alpine wetlands in the eastern Tibetan Plateau

Science of The Total Environment, 2019
Grazing-oriented drainage of alpine/boreal wetlands has been broadly implemented to meet the increasing demand for animal products. However, the annual methane (CH4) emissions from alpine fens degraded due to drainage for grazing have not been well characterized due to a lack of year-round observations.

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 ...

Models as multiple working hypotheses: hydrological simulation of tropical alpine wetlands

Hydrological Processes, 2010
Tropical alpine grasslands, locally known as paramos, are the water towers of the northern Andes. They are an essential water source for drinking water, irrigation schemes and hydropower plants. But despite their high socio-economic relevance, their hydrological processes are very poorly understood.

[Research on algal diversity in Zoige Alpine Wetland].

Huan jing ke xue= Huanjing kexue, 2013
Water samples were collected in summer and winter in Zoige Alpine Wetland. Both the traditional cultivable and microscopic method and modern molecular approach were used to reveal the algal diversity in the wetland. For the samples collected in summer, single-cell Chlorophyta was cultured, isolated and identified.

Investigation of bacterial community diversity in water of Zoige Alpine Wetland

Acta Ecologica Sinica, 2011
Abstract Spatial isolation is currently thought to represent one of the major factors resulting in bacteria genetic variation and population abundance. The bacterial diversity in a distinct environment Zoige Alpine Wetland located in the northeast of the Qinghai-Tibetan Plateau with the altitude 3400 m on average aroused our great attention.
