Abstract: The climate change prediction in China based on OCU model as well as summary analysis of GFDL, GISS, NCAR, OCU and UKMO models are used for discussing the approaches to predict the response of the forests in China under double concentration of atmospheric carbon dioxide after about 2020. The growth, production and distribution boundary of Chinese fir (Cunninghamia lanceolata), the tree composition and their growth in cold temperate Oaxingan Mountain region, and potential forest zones in China as examples are discussed in this paper.

Key words: Global climate change, Forests in China
