摘　　要：以支提山上的突脉青冈天然林群落调查资料为基础,对突脉青冈天然林树冠结构及其与胸径和树高的相关性进行探讨和分析.结果表明:随着林分径阶的增大,冠长的整体变化趋势是显增大,相对冠长是显现增加的趋势,但增加幅度不大,树冠系数的变化趋势也相似,但生长潜力在后期较大;根据拟合方程的斜率,说明了胸径对突脉青冈树冠发育的影响小于树高对其的影响.这些研究,为科学地经营管理突脉青冈天然林、寻求合理有效的经营管理模式提供理论依据.Based on the investigation of the Cyclobalanopsis elevaticostata forest in the mountain of Zhiti,we studied the canopy structure and its relationship with the height of stand and the diameter stand.The results showed that,with the increase of the stand diameter,the overall trend of crown length was significantly increased.The relative crown length showed a tendency of marginal increase,and the canopy coefficient trends were similar.Whereas,the latter growth potential was larger.According to the slope of the regression equation,the paper illustrated that the effects of diameter breast height of Cyclobalanopsis elevaticostata crown development was less than the height.Hence,the paper provided the theoretical basis for the scientific management of natural Cyclobalanopsis elevaticostata forest for seeking a rational and effective business management mode.
