摘　　要：以吉林省汪清林业局金沟岭实验林场62株红松解析木数据为基础,探讨Hegyi竞争指数对红松单木断面积5 a生长量的影响,并构造线性模型。结果表明:在5 a前年龄5、a前直径、5 a前树高、第一活枝高度、第一死枝高度、活树冠长度、竞争指数等变量中,仅有5 a前树高与对数断面积生长量相关性显著,进入模型,其余指标未能进入模型。The influence of Hegyi＇s competition index （CI） on the basal area increment （BAI） of Korean pine was presented based on the stem analysis data of 62 Korean pine trees from Jingouling Experimental Forest Farm of Wangqing Forestry Bureau, China. The results showed that only the index of the height at 5 years ago was significantly correlated with BAI among the 7 variables （tree age at 5 years ago, DBH at 5 years ago, height at 5years ago, height to the live branch, height to the death branch, live crown length and CI）, and it entered the model rather than the left indices.
