摘要
本文运用层次分析法对定性因子进行量化处理,建立了较为理想的落叶松林生产力回归模型。研究结果表明:平均胸径和树种组成是影响落叶松林生产力较为重要的因子,而林型在人为干扰的条件下对落叶松林生产力的影响已被削弱。
Multiple linear regression models of Larch forest productivity were worked out by quatifing the qualitative factors through AHP (Analytic Hierarchy Process) in this paper.The results of studies show that mean diameter in breast and species composition are more important factors affecting the productivity of Larch forest;and in the condition which is disturbed by man,the influence which exerted on the productivity of Larch forest by forest type has been weakened.
