| 摘 要： | 根据在白桦（Ｂｅｔｕｌａｐｌａｔｙｐｈｙｌｌａ）种群分布区内所选择的四个代表性地区的定位观测资料，本文运用数学分析方法，采用电子计算机进行运算，模拟，研究白桦种群的空间分布格局。结果表明：随着生境温度的逐渐降低或温度的逐渐升高，白桦种群由聚集分布过渡为随机分布，随着种群年龄的增加，种群空间分布格局表现出相同的变化规律。

| Abstract: | ccording to the examined data from fixed positions which are located at four typical sites in the range of Belula platyphlla, this paper adopts the methods of mathematical analysis in the study of the spatial patterns of Betula plalyphylla population with computer calculation and imitation. The results show that with the drop in humidity or the rise in temperature of habitat, the distribution of Betula platypllylla population turns from concentrated to random and with the rise in age, the population shows the same rule of spatial patterns. |
