Abstract/Summary:
Climate changes have the potential to influence the temporal stability of plant community biomass in Qinghai-Tibet Plateau, but most studies were based on short-term field climate manipulation experiments, the response of biomass stability of natural alpine meadow remain largely unexplored. We conduct a 20-year experimental study in eastern QTP with linear regressions and a path analysis of annual temperature, annual temperature range, annual precipitation, annual precipitation distribution, biomass stability of grass, biomass stability of forb, community asynchrony to assess the influence climate change and biological factors on the temporal stability of plant community biomass, we find that it was community asynchrony rather than climate change determine the temporal stability of plant community biomass and alpine meadow ecosystems are resistant to climate change. Our findings suggest that future climate change may have considerable uncertainty about the temporal stability of plant community biomass in the alpine meadow and we should combine with both field climate manipulation experiments and long-term observational experiments to assess the influence of climate change on the temporal stability of plant community biomass.
