摘要
以广东省翁源县青云森林公园6种不同林分为研究对象,采集土壤样品进行理化性质分析,并利用主成分分析法进行评价,揭示不同林分土壤特性的差异,为森林公园资源保护管理与改造提供依据。结果表明,6种林分土壤理化性质优劣顺序为:白水寨毛竹林>天然居针叶混交林>下鹿角幼杉林>水缸阔叶林>烂泥坳桉树林>下排马尾松林。
To provide references for natural resource protection and management, six types of stands in Qingyun forest park were used as soil samples and their physical and chemical properties were comprehensively evaluated by principal component analysis（PCA）. Based on the PCA comprehensive evaluation results, the superior order of 6 forest stands were ranked as follows： Phyllostachys heterocycla forest of Baishuizhai coniferous mixed forest of Tianranju broad-leaved forest of Shuigang Chinese fir plantation of Xialujiao eucalyptus plantation of Lanni＇ao masson pine plantation of Xiapai.
