基于大小比数的林分空间优势度表达方法及其应用
|
摘要
以大小比数为基础,结合比较指标的变化幅度,提出了林分空间优势程度的量化表达方法,并以6块红松阔叶混交林样地和2块锐齿栎针阔混交林样地调查数据对林分空间优势度的表达方法进行验证。结果表明:基于大小比数的林分空间优势度表达方法能够很好地反映出林分整体的空间优势程度,而且能够表达出林分经营前后的空间优势程度变化,可以用来评价森林经营措施的得当与否及经营效果的优劣。此外,林分空间优势度量化表达方法为实现构造森林空间结构优化目标函数提供了依据。
Based on the neighborhood comparison and combined with the comparative indicators of variations in size,the paper puts forward a quantify method describing the stand spatial advantage degree. The investigated data of 6 plots in Korean pine-broadleaf mixed forest and 2 plots in Quercus aliena natural forest were used to test and verify this method. The results show that the method not only can express the stand spatial advantage degree but also the changes of stand spatial advantage degree after management,and it can be used to evaluate the forest management measures and operating results. Also,stand spatial advantage degree quantify method provids basis for the realization of optimized objective function for forest spatial structure.
