天然阔叶林建群树种若干测树因子相关关系的探讨

依据福建省天然阔叶林主要分布区的林分标准地资料，对天然阔叶林建群树种的树高与胸径、枝下高与胸径、冠幅与胸径、树高与枝下高、冠幅与树高间的内在关系进行探讨，结果表明，其存在显著的相关关系，揭示了天然阔叶林建群树种几个测树因子的生长规律，为天然阔叶林经营、林地生产力评价、森林收获预估等提供依据。

Probe into the Relationship among Some Dendrometer Factors of the Tree Species Constructing Broad- leaf Forest Community

According to the materials of forest distribution standard of main distribution area of natural broad - leaf forest of Fujian Province, the essay probes into the inter-relationships between the tree height and trtmk diameter, the height beneath the branch and the trunk diameter, the extent of tree crown and the trtmk diameter, the tree height and the height beneath the branch, and the extent of tree crown and the tree height. The result shows that obvious relationships exist among these factors, revealing the growing rules of these dendrometer factors of constructing community plants in natural broad-leaf forest, which provide the basis for the operation of the natural broad- eaf forest, assessment of the forest land productivity and pre-evaluation of the forest harvest.
