摘要: 结合试验地调查以及林分内树种组成,利用混交度(M)、大小比数(U)和角尺度(W)3个林分结构参数,分析了叶山林场常绿阔叶混交林林分空间结构。结果表明:该林分平均混交度为0.371 8,主要树种麻栎多呈单种聚集,其余树种中强度混交比例达到96%;平均大小比数为0.493 6,在林分空间配置上,马尾松处于优势状态,其余树种分化严重;平均角尺度为0.518 9,混交林的分布格局基本上以团状分布为主。

关键词: 常绿阔叶混交林, 空间结构, 角尺度, 混交度, 大小比数

Abstract: Based on experimental investigation and species composition,stand spatial structure of evergreen broad leaved mixed forest was investigated by using three structure parameters(mingling,neighborhood comparison,and uniform angle index-neighboring tree distribution pattern).The results showed that the average stand of mixed is 0.3718,main tree species-Quercus acutissima mostly single gathered,the mixed proportion of remaining species about 96%.The average neighborhood comparison is 0.4936,P.massoniana in a dominant state and the rest of the species differentiation seriously on the stand spatial configuration.Average neighborhood pattern is 0.5189,the stands were found to be a clumped distribution in this community.

Key words: evergreen broad leaved mixed forest, spatial structure, neighborhood pattern, mingling, neighborhood comparison
