According to the wide-ranging data on geographical distribution of Gordonia acuminata, several indexes widely used for the study of vegetation-climate interaction were applied. The relationship between the distribution of G. acuminata and climatic hydrothermal condition had been analysed, and the Kira^s water-temperature indexes for the upper, lower and north limits of the vertical distribution of G. acuminata were discussed. The principal component analysis showed that relative effects of climatic hydrothermal indexes on the distribution of G. acuminata were in the order thermal factor>precipitation factor>accumulated sunshine time>relative humidity. The potential changes of G. acuminata distribution area under elevated CO_(2) concentration were predicted by using Holdridge^s index of life zone classification system and gas circulation model^s conclusion.
