| 摘 要： | 应用相关系数指标研究了３８年生杉木生长性状的早晚相关性，结果表明，杉木生长性状在２年生时与采伐（３８年生）时的相关系数在统计上是显著的，其后相关系数逐年上升，到优树选择（１５年生）时相关系数达０．９１６．相关极为显著；杉木林分内个体间竞争对个体生长的影响较小。同时，探讨了杉木群体的遗传变异较小的原因。

Studies on the Early－Late Correlation of 38－Year－Old Cunninghamia lanceolata Growth Characters |
| |
| Abstract: | The correlated coefficlent index was applied to study the early－late correlation of 38-year-old Cunning-hamia lanceolata growth characters and the results reveal that the correlated coefficient between the growth charac-ters of 2-year-old C.lanceolata and the growth characters of the felling time of C.lanceolata（at the age of38）is statistically significant．Meanwhile the causes of less genetic variation of C. lanceolata population were alsoappmeched. |
