Abstract: It is the important objective of the core project "Global Change and Terrestrial Ecosystems (GCTE)" of International Geosphere-Biosphere Project (IGBP) to predict the feedback of terrestrial ecosystems on atmosphere and climate and the responses of the structure and function of ecosystems, natural and managed, to global change in finer scales. A lot of achievements in scientific research have been made, since Chinese scientists took part in the "Global Change Study" in 1985. The comment on the mechanism of responses of natural and managed ecosystems in China to doubled CO2 concentration and climatic change, modeling responses of Chinese terrestrial ecosystems to global change, possible effects of global clinkatic change on China' s desertification, and the study on Northeast China Transect (NECT) made recently by Chinese scientists will be presented. The interplan study should draw more attention in the future, and some important tasks will also be pmposed.

Key words: Global change, Ecophysiological experiment, Modeling, Desertification
