Abstract: In the study, height index of tree was taken as the index number of effect of climatic factors. Throgh analysis of multivariate Linear stepwise regression equation and principal component analysis, the results wers as follows:Korean pine was a relatively sensitive species iu response to climatic facors. The effect of climatic ecology factors on the growth of Korean pine was complex because different kinds of climatic ractors did not exist independently and they effected each other and restricted each other. Those factors effected Korean pine directly and indirectly in forms of single dominance or synergy or antagonism. The effect of climatic ecology factors on Korean pine was integrated influence of different factors. And each factor has differentinfluence on growth of Korean pine. The greatest iufluence was≥10℃ acumulative temperature, that was 52.79%. Raifall was the next to it, makingup 18.62%. The influence of the two was 71.41%, which were leading fa-ctors effecting Korean pine growth. regression equation was Y=0.2924577+6.26395531×10^-5x₂+6.45308913×10^-5x₄ (x₂=rainfall, x₄=≥10℃ acumulative temperature.)
