本文采用定量分析方法,在云南密山市立地因子进行科学评价的基础上,以影响林木生长的坡度、坡位、土壤种类和黑土层厚度等四个主导因子,将适宜发展速生丰产用材林的宜林地划分为三个立地类型组,九个立地类型,并确定了每个立地类型适宜营造的树种。 Based on the scientific evaluation of the local factors in Mishan City, Yunnan Province, this paper uses the four dominant factors of slope, slope position, soil type and thickness of black soil layer that will affect the growth of trees. The woodlands are divided into three site type groups and nine site types, and tree species are created that are appropriate for each site type.
