Abstract: In this study,the stepwise regression method is used to explore the relationship between tree growth and climatic factors of Pinustabulaeformis in the source areas of the Liaohe River.Results indicated that the dominant factors notably influencing the radial growth of Pinustabulaeformis are annual evaporation,annual sunshine duration and yearly precipitation; the major factors obviously influencing the elongation growth of Pinustabulaeformis stem are annual evaporation,annual sunshine duration and yearly precipitation.Thus,we can conclude that the climatic factors having a noticeable effect on the growth of Pinustabulaeformis are annual evaporation,annual sunshine duration and yearly precipitation.

Key words: Pinustabulaeformis, climatic factor, correlation analysis, the source areas of the Liaohe River
