混交林分森林资源资产评估技术研究

Forest Resources Asset Evaluation of Mixed Forests Stand

相对于纯林来说,混交林组成树种多样、林分结构较为复杂,加之混交林各组成树种年龄的差异,导致混交林资源资产评估技术也较为复杂。经过多年实践,针对混交林分树种组成的不同及林分结构特征,采用树种组成比例系数法确定主要树种和次要树种后,再根据各组成树种年龄的不同,确定相应的评估方法及评估模型。

Relative to pure forest, mixed forest has features of tree species varied, complex stand structure, different species age, that lead to mixed forest resources assets assessment techniques are more complex. After years of practice, according to the mixed forests characteristics of different species composition and stand structure, using species composition ratio coefficient method, the main tree species and secondary species are determined, moreover, according to the age of different tree species, appropriate assessment method and assessment model are also determined.
