Abstract: The paper includes 4 parts: 1. A short review of the history of studies on the distribution of forestvegetation in Eastern China, and highlighting the problems about the vegetation zonation of this region; 2. Expounding the principle and criterion of vegetation zonation: the vegetation features, especially the biocoenosis assemblage of each region should be taking as the main basis, and the floristic characteristics as well as the climate indices taking as the important factors of references of vegetation zonation; 3. According to this principle, the forest vegetation of Eastern China was divided into 6 zones: boreal needle-leaved forest zone, cooltemperate mixed needle broad-leaved forest zone, temperate deciduous broad-leaved forest zone, warmtemperate mixed evergreen deciduous broad-leaved forest zone, subtropical evergreen broad-leaved forest zone, tropical rain forest and monsoon forest zone; 4. Final explanation of the reason for changing the term and boundary of some vegetation zones; especially discussing which bioclimatic zone should be the mixed evergreen-deciduous-broad leaved forest and evergreen broad-leaved forest belong to. In the author's opinion, it is appropriate, that the former belongs to warm-temperate vegetation and the latter still belongs to subtropical vegetation.
