In order to understand the response of gross primary production (GPP) and above-ground biomass (AGB) warming, a field warming experiment using open-top chambers was conducted in an alpine meadow at three elevations (i.e., 4313, 4513, 4693 m) on Northern Tibetan Plateau May 2010. We calculated GPP from moderate-resolution imaging spectroradiometer algorithm AGB surface measured data 2012. Average elevation 4313 m significantly decreased by experimental whereas declines 4513 were not...
There is growing evidence that land-use management practices such as livestock grazing can strongly impact the local diversity, functioning, and stability of grassland communities. However, whether these impacts depend on environmental condition propagate to larger spatial scales remains unclear. Using an 8-year exclosure experiment conducted at nine sites in Tibetan Plateau covering a large precipitation gradient, we found herbivore exclusion increased temporal alpine biomass production...
Temperature and water conditions affect vegetation growth dynamics associated spectral measures. We examined the response of growing season maximum enhanced index (MEVI) to temperature, precipitation, vapor pressure relative humidity on Tibetan Plateau. The responses MEVI climatic factors changed with type, which may be attributed finding that background values factor changes varied type vegetation. spatially averaged over entire plateau exhibited a non-significant decreasing trend....
The VEGETATION (VGT) sensor in SPOT 4 has four spectral bands that are equivalent to Landsat Thematic Mapper (TM) (blue, red, near-infrared and mid-infrared bands) provides daily images of the global land surface at a 1-km spatial resolution. We propose new index for identifying mapping snow/ice cover, namely Normalized Difference Snow/Ice Index (NDSII), which uses reflectance values red TM VGT. For data, NDSII is calculated as NDSIITM=(TM3-TM5)/(TM3+TM5); VGT NDSIIVGT=(B2-MIR)/(B2+MIR). As...
Abstract: The increase of coverage forest/vegetation is imperative to improve the environment in dry‐land areas China, especially for protecting soil against serious erosion and sandstorms. However, inherent severe water shortages, drought stresses, increasing use competition greatly restrict reforestation. Notably, water‐yield reduction after afforestation generates intense debate about correct approach forest management areas. most studies on forests have been at catchment scales, there...
Species richness and diversity indices (Shannon-Wiener index, Simpson dominance index Pielou evenness index) in alpine grassland ecosystems (alpine meadow, steppe desert steppe) under grazing—excluded freely grazed sites were investigated along the Northern Tibetan Plateau Alpine Grassland Transect during summer 2009 2010. We found that species have not been significantly altered by short—term grazing exclusion since 2006 at vegetation regional scales. mainly driven growing season...
Tibetan alpine grasslands are viewed to be sensitive climate change and grazing disturbance. But it is not well understood how what extent exclusion affects species assembly on the Northern Plateau. We conducted a multisite transect along precipitation gradient detect compositional changes at 25 grazed versus nongrazed paired pastures in summers of 2009 2010 Changtang Natural Reserve. Species richness relative frequency were estimated for plant functional groups (PFGs: grasses, sedges,...
