Spatial Analysis Applying to Study"Global Warming Impacts on Alpine Vegetation Dynamics"

The 6th ENGII Conference(Workshop6 2014)——This study is to illustrate alpine vegetation dynamics in Qinghai-Tibetan Plateau of China from simulated filed experimental climate change, vegetation community dynamic simulation integrated with scenarios of global temperature increase of 1 to 3℃, and simulated regional alpine vegetation distribution changes in responses to global warming. Our warming treatment increased air temperatures by 5℃ on average and soil temperatures were elevated by 3℃ at 5 cm depth. Aboveground biomass of grasses responded rapidly to the warmer conditions whereby biomass was 25% greater than that of controls after only 5 wk of experimental warming.
