商品林建设基地的立地质量评价及类型划分

以龙竹造纸原料林基地的立地质量评价与类型划分为例,提出在商品林建设基地中,应针对发展树种和培育目标合理确定立地质量评价指标,根据树种的一物学特性和立地因子测定难易程序,结合林业生产定性初选立地因子,采用“数量化-Fuzzy聚类立地分类方法”评价造林地的立地质量及划分立地类型,对造林基地而言,将对基地建设更具有现实指导意义。

The Assessment and Differentiation of Site Quality of the Commercial Forest Base

This paper put forward that the indexes for the site quality assess should be decided in the light of the favored tree species and cultural aims reasonally in the construction of commercial forest base with a example from that of paper-making Dendrocalumus forest base. The factors of site were preliminarily chosen quantitatively, according to the biological characteristics of tree species and the difficulty degree of site quality measurement combined with the forest production. The approach of "Fuzzy Clustering for the sites"was adopted to assess the site quality of afforesting land base concerned,this was of living guide significance for afforestation base construction.
