Abstract:Spatial variation patterns of species biodiversity and biomass, together with the response of their correlation to increasing temperature under global warming conditions, are hot topics in ecological researches. Such patterns are also the keys to explore the response process of community stability to global warming. Species distribution was produced by interaction of multiple ecological processes. Temperature increment affected species diversity by modifying the function of key species in communities, and thus altered the community stability. As for the response process of grassland community stability to global warming, many scholars have conducted researches, but their conclusions have revealed large discrepancies. In the present work, species biodiversity and biomass were reviewed from their spatial variation pattern, response to rising temperature, and interactive correlation, combined with our own research results from the QinghaiTibetan Plateau and the Loess Plateau. Key research directions were then proposed in the study of the response of grassland community stability to global warming.
