江西森林立地质量数量化评价研究

A STUDY ON THE EVALUATION OF QUANTIFICATION OF THE FOREST SITE IN JIANGXI

以立地亚区为单元,采用数量化理论(Ⅰ)、逐步回归、交互逐步回归、广义方差分析方法,对杉本、马尾松数量化建模进行模型选比研究,从中选定数量化理论(Ⅰ)方法,建立各立地亚区杉木、马尾松的预测模型,编制出相应数量化地位指数得分表,筛选出影响杉木、马尾松生长的主导立地因子。

By means of quantification theory(Ⅰ),stepwise degression,cross stepwise degression and broad-sense analysis of variance,regarding each site subzone as a unit,the comparisons among the quantification models of Chinese fir and Mason pine were completed.The forecasting models of Chinese fir and Mason pine in each subzones were constructed according to the selected model of quantification theory(Ⅰ).The concerned score table of the quantification site index was made. The leading factors affecting the growth of Chinese fir and Mason pine were picked out.
