广东南洋楹主要栽培区立地分类及其适生性的研究

A STUDY ON THE SITE CLASSIFICATION AND SUITABILITY FOR Albixia falcata IN MAIN CULTIVATED AREAS OF GUANGDONG

本文根据82块样地调查分析的数据,用逐步回归和主成分分析的方法筛选出广东南洋楹主要栽培区立地分类的主导因子为坡位、坡型、母岩与地貌.根据这些因子,对栽培区的立地作了逐级控制分类;并对不同立地等级的林分生产力及各立地类型对南洋楹的适生性作了讨论.

The slope position, slope-shape, mather rock and landforme are leading factors of site classification on main cultivated areas of Albixia falcda in Guangdong province, which were selected by Multiple regression and Main-element analysis in this paper. According to these leading factors, the site of cultivated area was classified by gradual control. This paper also evaluates the productivity and suitability of Albxia falocia growing in different site unite of the cultivated area.
