通过选取异龄、混交两大因子的10个指标,绘制“结构树”以描述水源涵养林复杂的林分结构,使林分结构的表达方式可视化。研究结果表明,“结构树”将水源涵养林分龄级与混交比相互关系的可视化,可以为建立林分结构与水源涵养功能的量化模型、林分结构调整、不同林分结构间的比较以及指导森林资源调查提供了一种新的思路与方法。
By selecting ten indicators of age and mixed with two factors, we draw “Tree” to describe the complicated stand structure of water conservation forest so that the expression of stand structure can be visualized. The results show that visualization of the relationship between age-grade and mixed-ratio of water conservation forest can be used to establish a quantitative model of stand structure and water conservation function, structure adjustment of stand, structure of different stands Compare and guide the forest resources survey provides a new way of thinking and methods.
