| 摘 要： | 过伐林是原始阔叶红松林经不合理采伐后，郁闭度仍在０．４以上的林分．本文以东北东部山区典型的过伐林区——白石山林区为例，研究了主要过伐林的重要数量特征；确定了主要树种的存在度等级；计算了不同群落样地间的相似系数；最后用极点排序法将过伐林群落划分为四个主要类型

| 关 键 词： | 过伐林 群落数量特征 存在度 极点排序 |

| Abstract: | Post cutting forest refers to the forest type formed after the original hardwood Korean pine forests were carelessly logged but remained a canopy density of more than 40 percent Based on the data of sample plots collected in Baishishan Forest Area of Jilin, the typical distribution area of post cutting forests in the eastern region of northeast China, quantitative characteristics of the forest communities, presence of the main tree species, similarity indices between the communities were determined and analyzed Finally,the forest communities were divided into four major types by using polar ordination |
