浙江省国有林场森林资源特征研究

Forest Resource Characters of State-owned Forest Farms in Zhejiang province

摘要: 基于浙江省2015 年国有林场森林资源调查数据，运用主成分分析方法，分析了总经营面积、林地面积占比、林地利用率、森林总蓄积、单位面积森林蓄积、森林覆盖率、公益林面积、木材产量、竹材产量、自然保护区面积、风景名胜区面积、造林面积占比12 个森林资源因子的相关关系，并将12 个因子降为代表森林资源特征的5 个主分量；基于5 个主分量采用系统聚类法，将100 个国有林场划分为9 类。

Abstract: Principle component analysis were made on total management area, area of forest, utilization ratio of forest land, forest volume, forest stock per unit area, forest coverage rate, ecological forest area, timber yield, bamboo culm yield, area of nature reserve, area of scenic spots and proportion of plantation area, based on the forest resource inventory data of the state-owned forest farms in Zhejiang province in 2015. Hierarchical clustering analysis on 5 principal components representing forest resource features indicated that 100 state-owned forest farms could be divided into 9 groups.
