Abstract:Climate change has become a severe ecological threat faced by the present biological organism. Climate warming and the changing of precipitation regimes have led to the change of biological organism’s traits, inter-species relationship, species distribution, and biodiversity, thus affecting the ecosystem function and stability, with the biological organism as the main body, and consequently affecting human’s survival and society’s sustainable development. This paper describes the progress of research in the response of biodiversity and ecosystem function abroad and at home to the climate change. In combination with the problem existing in this field, this paper proposes that China should use the leading academic thinking of the existing basic research on climate change-biodiversity-ecosystem stability and feedback regulation, research method and research priority, so as to entirely expound the mechanisms of interactions between biodiversity, terrestrial ecosystems and climate change, which will provide scientific basis for reasonably using natural resources and adaptable management, and pushing forward the overall development and breakthrough of the Chinese researches on biodiversity and on global change ecology.
