| 摘 要： | 本文对吉林省延边地区天然赤松林（平均年龄为４０年）的直径分布进行了分析，认为随着林分密度的增大，天然赤松林的胸径分布表现出由正态分布型转向韦布（Ｗｅｉｂｕｌｌ）分布型，偏度由负偏趋于正偏，峭度逐渐变大的动态分布规律．可供合理经营等参考使用．

| Abstract: | The D.B.H distributions of natural Japanese red pine forests in Yanbian area were reported. With the increase of stand density, the D. B. H. distributions of natural Japanese red pine forests could be expressed by curves that changed from normal to Weibull shapes.The skew degrees tended to chance from negative to positive and kurtosis degreased gradually.These models can be used for the reasonable management of forest resources. |
