Abstract: Based on the literatures with the subject headings “Climate Change” and “Forest” collected from the CNKI and Google, and according to the regional vegetation types within China, the meta-analysis method was used in this paper to assess the effects of climate change on China forest ecosystems. Among the observed effects of climate change, those on the tree phenology, forest productivity, and forest fire of the regional vegetation types were similar, but definite differences were observed in the effects on the forest geographic distribution. As for the projected effects of climate change, those on the tree phenology, forest productivity, forest carbon storage, and forest fire of the regional vegetation types were similar, but there were some differences in the effects on the forest geographic distribution and forest structure. The main problems of the existing studies and the directions of future researches were also discussed.
