中文摘要:全球变暖背景下物种多样性和生物量的空间变化格局及其对温度升高的响应是生态学研究的热点内容,是探究群落稳定性响应全球变暖的关键。物种分布是多个生态过程相互作用的产物,温度升高通过改变群落关键种的作用影响物种多样性,从而改变群落稳定性。关于草地群落稳定性对全球变暖的响应过程,国内外学者的相关研究存在很大差异。该文作者结合自己研究团队在青藏高原和黄土高原的研究成果,对近年来国内外有关草地群落物种多样性和生物量的空间变化格局及其对温度升高的响应、以及二者的相互作用关系等方面的研究进展进行了综述,并提出了草地群落稳定性对全球变暖响应研究的重点方向。

Review of Response of Grassland Community Stability to Global Warming Based on Correlation between Species Biodiversity and Biomass
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 Qinghai Tibetan Plateau and the Loess Plateau. Key research directions were then proposed in the study of the response of grassland community stability to global warming.
