耐寒桉树立地类型划分及评价

采用聚类分析和逐步回归分析的方法,分析影响桉树生长的主导因素,确定立地分类系统,划分立地类型,评价生产力。根据桉树立地条件分析结果,提出了以海拔、局部地形、土壤因素为主的三级分类系统。本分类系统按海拔划分出2个类型区,以坡位划出6个类型组,以土壤温度、成土母质和腐殖质层厚度划分出26个主要立地类型。

Site type classification and evaluation of cold-resistant eucalyptus

Using the methods of cluster analysis and stepwise regression analysis,the main factors influencing the growth of eucalyptus were researched to define the site classification system,divide site type and evaluate productivity.According to the site conditions of eucalyptus,the three-level classification system based on altitude,local terrain and soil factors was put forward.There were 2 site type districts divided along altitude,6 site type groups divided along slope position and 26 site types divided along soil temperature,soil parent material and humus layer thickness.
