| 摘 要： | 本文用多元回归分析方法分析了粤北3个林场杉木林的立地指数与立地园子的相关,筛选出影响杉木生长的主导因子是坡位、(?)殖层厚度、土层厚度与海拔调试。根据主导因子,定性定量相结合,划分为2种立地类型小区、6种立地类型组、14种立地类型。同时,导出评估杉木林生产力的预测方程,评价不同立地单元的杉木林生产力。

| Abstract: | Multiple regression analysis was used to study the relationships between site index and site factors In the study area.The results showed that the main site factors were slope position,the depth of humus horizon,the depth of soil horizon and the elevation.The study area was classified into 2 site type districts,6 site type groups and 14 site types.The forecast equation for site index was derived to predict stand productivity of (?) lanceolata.This paper also evaluates the productivity of plantations of C.lanoeolata in different site units of the study area. |
