摘要
对沾益县2004年森林资源二类调查设置的948块样地和专业调查资料进行综合分析,选定以沾益县分布广泛的云南松作为评价树种对林业用地进行立地质量评价.将不同立地类型上的云南松样地的林分蓄积换算成标准年龄、疏密度为0.80的标准林分蓄积,利用星座聚类法分析,划分各立地类型的立地等级,并对其中存在的问题进行了讨论.
The professional inventory data and 948 sample plots for No. II forest resource inventory in Zhanyi in 2004 were comprehensively analyzed. Pinus yunnanensis which extensively distribute in Zhanyi county was chosen as a particular species for site quality assessment.
