选取长白山地区3块面积分别为0．5 hm2的样地的13个树种共1169株林木，采用SPSS、Winkelmass软件进行相关性与空间位置分析。结果表明：该地区林木胸径生长量与其相邻木距离的相关系数为0．938；每个树种相邻木都会出现本身的树种；多数的树种都是随着距离的增大胸径生长量增大，影响对象木生长的相邻木距离范围是1．8～3．7 m。

A total of 1 169 trees of 13 tree species from three forestry bureau level plots of the 0.5 hm2 in the Changbai Mountain were selected to analyze the correlation and spatial position in order to ascertain space structure of 13 tree species by SPSS and Winkelmass software, which had a theoretical significance for forest management and intermediate cutting.Results showed that the correlation coefficient of DBH growth and neighboring trees distance was 0.938 and every tree species a-round appeared itself.DBH growth showed more or less increase with the increase of distance.The distance of neighboring trees which affected the growth of subject tree ranged from 1.8 m to 3.7 m.
