面向自然资源资产清查的云南森林资源均质区划分研究
Study on the Division of Forest Homogeneous Zones in Yunnan for Natural Resource Asset Inventory
摘要
Abstract
Based on the spatial differences in 17 factors associated with forest resource quality such as forest origin,volume per unit area,elevation,slope,topographic relief,climatic conditions and socio-economics among counties in Yunnan Province,the degree of similarity of forest resources was expressed in spatial distance between county units and Yunnan Province was classified into spatially more consistent homogeneous units by K-mean clustering and hierarchical clustering respectively.The results show that K-mean clustering is more ef-fective,dividing Yunnan Province into 6 homogeneous zones,showing more conductive,aggregated and coher-ent in practice.In addition to considering the attributes of forest resources,the introducing of economic and an-thropogenic factors in the cluster analysis can reflect the regional difference in forest resources more objectively.The study can provide reference for constructing the price system of national forest resource asset inventory and asset accounting,and has important theoretical and practical value for supporting the national forest resource in-ventory work.关键词
