Abstract: According 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.

Key words: Betula platyphylla, Population, Spatial pattern, Concentrated distribution, Random distribution
