青山湖森林公园针阔混交林大小比数的研究

Neighborhood Comparison of Mixed Conifer and Broadleaved Forest in Qingshan Lake Forest Park

该研究通过对青山湖森林公园内亚热带针阔混交林各树种的不同大小比数进行比较分析,得知以胸径和树高大小比数反映林木的大小分化程度较冠幅大小比数可靠,同时林木竞争过程中胸径和树高的分化程度最大。林分中的优势种马尾松的大小比无论在胸径还是树高上都优于其他树种。

The neighborhood of different tree species of subtropical mixed conifer and broadleaved forest in Qingshan Lake Forest Park was compared and analyzed.The neighborhood of diameter at breast height and tree height reflected the differentiation degree of trees more reliably than the size of canopy breadth.The differentiation degree of diameter at breast height and tree height in the competition process of trees was the greatest.The neighborhood of the dominant species masson pine in forest stand was superior to other species both in the diameter at breast height and tree height.
