摘　　要：本文采用动态可比性林木分级法，研究了东北东部天然赤松林的种群结构.根据天然赤松林种群的立木结构特点将其分为A、B、C三种类型．分析了立木结构类型对种群生产力的影响，并针对每种类型提出了经营意见.The method of dynamic comparable tree classification was introduced to study the population structure of natural Japanese red pine forest in Northeast China. Based on the characteristics of tree structure the natural Japanese red pine population was divided into three types: A, B,C. The effect of tree structure on the population productivity was analysed and management strategy for each type was also put forword in this paper.
