摘　　要：利用红松在辽宁东部地区两个参试点的生长资料,从生态遗传学的角度出发,利用典型性相关分析等方法,揭示了红松幼龄林生长性状的地理变异规律,即树高与地径是以海拔垂直梯度的渐变为主,纬向渐变为辅的连续型变异。红松幼龄林的生长表现为由北到南,由高海拔到低海拔生长量逐渐增大的趋势,这些趋势体现出对南北温度条件差异的适应性,特别是对低温的适应。在影响红松地理变异的因素中,温度和水因子是重要因素,其中温度是主导因子。According to the growth records ofPinus koraiensis fi＇om two experiment fields in Eastem Liaoning Province of China, ap- plied canonical correlation analysis, geographic variation pattern on traits of tree height and root collar of P/nus koraJens/s are ex- plained in ecological genetics. The basic geographic variation pattem are the progressive changes of elevations mainly and latitudes subsidiary. The growth performances increase gradually as the locations from north to south and the altitudinal gradient fi^om high to low. These Irends are the adaptability of the north - south temperature difference, especially for low temperature stress adaptation. Tem- peratttre and water are the important factors among the factors that influence the geographic variation pattern of Pinus koraiensis, where temperature is the dominafing factor.
