摘要
本文运用数量化理论I模型对景宁厚朴林地位指数与多元立地因子之间的关系进行了回归。分析结果表明,在所选择的项目中对地位指数起主导作用的是土壤结构、土壤厚度和坡形。本文建立了数量化立地指数表,经检验证明,本表精度较高,可应用于生产实际。
With the method of quantitative theroy I model, this paper gives a regression equation which relates to the site index of officinal magnolia and some site factors. The results show that the factors which play a leading role are soil structure, soil thickness and slope shape. This paper establishs a quantitative site index table, too. The table has a high precision and is a practical table in the management of officinal magnolia.
