摘　　要：为了研究燕山山地栎类次生林的林分结构特征,采用样地调查法对栎类次生林的林分结构特征进行分析。结果表明:栎林按优势树种可分为槲树次生林、蒙古栎次生林、松栎混交林和阔叶杂木林4种类型,林分伴生树种多样,但以同龄单层林纯林为主,林分平均胸径和树高、蓄积量较低,森林质量较差,生态功能退化严重。森林经营中应根据不同类型栎林的结构特征,采用补植、疏伐和人工促进实生更新等措施促进森林发育。Quercus natural secondary forest is an important forest vegetation in Yanshan Mountain, and an important forest type for implementing natural forest protection and restoration. The structural characteristics of the forest stand are the basis for scientific forest management and management. The structural characteristics of the oak forest in this area were studied by using the sample plot survey method. The results show that the oak forest in this area can be divided into four types according to the dominant tree species: quercus secondary forest,Mongolian oak secondary forest,pine oak mixed forest and broadleaf mixed forest. The associated tree species in the forest are diverse,but the single layer pure forest of the same age is the main forest. The average diameter at breast height, tree height and stock volume of the forest are low, and the forest quality is poor, The ecological function is seriously degraded. According to the structural characteristics of different types of oak forests,measures such as replanting,thinning and artificial promotion of seed regeneration should be taken in forest management to promote forest development.
