Based on the distribution data of 22 dominant species of typical evergreen broadleaf forest of Castanopsis, Cyclobalanopsis and Lithocarpus (Fagaceae) and 11 climatic factors, the range types of these species and their relationship with environmental factors were analyzed by Correspond Analysis (CA) and Canonical Correspond Analysis (CCA). According to the result of CA, all could be roughly classified into two range types: east type and west type. The east type could be divided into two subtypes: south and north one. In accordance with the classification of species, the study region was also divided into three range regions: west region, northern east region and southern east region. According to the result of CCA, the major environmental factors of various spatial gradients were different. In east-west direction, the seasonality in temperature, mean temperature of the coldest month, sunshine duration, total actual solar radiation and aridity index had more effects on species distribution; while in south-north direction, the mean temperature of the coldest month and total potential solar radiation were the main limitations of the range of plants and played an important role on the northern boundary of species’ range region. Compared with other scheme of vegetation zonation of subtropical evergreen broadleaf forest zone, the boundary between eastern and western region of this paper was similar while the boundary between southern and northern region was north-leaned slightly.
