| 摘 要： | 针对在大区域森林资源连续清查中使用的一元立木材积表不能适用于该区域内任何县一级调查的问题, 提出了用树高曲线、相对欧氏距离和组平均法, 形式聚合图, 再截树的方法进行聚类分析研究, 使材积表在允许误差范围内, 对相近的县域进行归类, 为所编制的大区域的一元立木材积表适用于县级的调查提供理论依据。图2 表1 参10

| Abstract: | One-way volume table used in large scale continuous forest inventory is unsuitable for forest inventory of county-class in this region. To counter this problem, the cluster analysis method is offered. The procedure of cluster is as following: the cluster diagram is firstly made with tree height curve, relative Euclidean distance and class mean method, and then is divided into units. This method provided theoretical basis for classifying the similar counties within range of error, and for making regional one-way volume table being suitable for county-class forest inventory. |
