Classification of Forest Sites in the Bingla Mountain of Liaoning Province.

森林立地的研究是人工林集约经营的基础,正确地选择宜林地,科学造林,真正做到适地适树,必须进行森林立地分类。森林立地分类应是以现代森林生态学和生态系统理论为依据,研究植被(立木、下木、地被物)和地形、植被与土壤以及地形和土壤的关系。

Methods of step multiple regression, principal component analysis and canonical ordination analysis were used to determine dominant factors in relation to site classification. Forest site regions were classified by mid-physiography, forest site groups by slope direction and forest site types by soil physical conditions and depth of soil organic matter, 21 types of forest site were classified in the Bingla Mountain.
