| Abstract: | Global change and its possible impacts on ecosystems, especially terrestrial ecosystems, have seriously affected the human life-supporting environment and the sustainable development of social economics. It has drawn more and more attention from the governments, scientists and the public. The advance in the study on terrestrial ecosystems and global change (climate change, atmospheric composition change and land use change) has been reviewed in this paper from three aspects: the processes and mechanisms of the interaction between terrestrial ecosystems and global change, possible effects of global change on Chinese terrestrial ecosystems and the feedback of changing terrestrial ecosystems on global change including terrestrial carbon cycling. The processes and mechanisms of the impacts of global change on terrestrial ecosystems would be given from plant ecophysiology, growth and development, allocation, water use efficiency and the metabolisms of carbon and nitrogen by doubled CO 2, raising temperature, water change, UV-B radiation and O 3 changes as well as human interference (land use change). The results indicated that the effects of global change on different plant species are different, and the adaptation strategies of different plant species should also be different. The responses of vegetation, forest ecosystems, grassland ecosystems and agricultural ecosystems to global change were described by their geographical distributions, phenology, structure and function as well as their ecosystem stability. The results suggested that different vegetation types/terrestrial ecosystems have different responses to global climate change, however there is a large uncertainties for their responses. Moreover, the feedback of vegetation on climate change has been discussed from the changes of dynamic and thermal parameters induced by vegetation change and potential carbon storage. The research results indicated that the evaluations on the feedbacks of vegetation/terrestrial ecosystems on climate are different from different researchers, and the feedbacks depend on vegetation types and land use change. Thus, the countermeasures related to negative effects of global change should be determined by different regions and different problems. Based on the hot issues of global change study at present, some important tasks related to the study on the interaction between terrestrial ecosystems and global change are also suggested. Among them, the quantitative assessment of adaptation practices should draw more and more attention in the future. |
