| 摘 要： | 以长白山红松阔叶林林冠木的年龄资料为基础，分析林木冠重叠与年轮径向生长的关系；通过林冠空隙边缘人隙边缘株的干扰释压分析，揭示林冠空隙集中形成的动态规律。红松林相邻林木间理论树冠重叠率与年轮径向生长呈显著负相关，不同树种间存在不同的竞争和协同关系；红松林中除个别小空隙是经过一个集中形成期形成外，大部分空隙是经过２－３个集中形成期形成的，１９００－１９２０和１９１０－１９３０是大部分空隙的集中形成期。

| Abstract: | The paper analyzed the relationships between tree crown overlapping and ring radical growth based on ring materials of canopy trees.The dynamics of gap focus formation was studied through disturbance release analysis of gap frontier trees.There are negative relationships between theoretical crown overlap rates and ring radical growth.There are various competitive and cooperative relations among various tree species.Most gaps formed in 2 or 3 gap focus formation periods except a few small gaps which formed i... |
