天然林;空间结构;混交度;大小比数;角尺度
摘  要：
利用混交度、大小比数和角尺度等3种结构参数,分析了天然林的空间结构。用平均混交度和混交度分布分析了林分的树种空间配置情况。结果表明:(1)该种林分主要以中、强度混交为主,树种之间的混交度属性差异很大;(2)该种林分以随机分布为主。同时还应用大小比数分析各个树种大小比数分布,以判断各树种林木的大小分化程度,得出栎林在生长上占有一定优势。

摘  要：
In this paper,three parameters were considered to be the suitable ones to describe stand structure completely.The first one was mingling,which could be used to analyze the spatial distribution and isolation of species in the stands;The second one was neighborhood comparison,which could be used to characterize the size differentiation of trees;The third was neighborhood pattern,which could be used to describe the distribution of tree positions.The three parameters were used together in analyzing and describing spatial structure of nature forest.Moderate and intensified mingling were found in the stands.There existed significant differences among species in mingling propertie.Random distribution was the main spatial characteristics for most stands.Meanwhile,neighborhood comparison was used to analyze the distribution of all kinds of species,and to judge the differentiation degree of all species.It was found that Quercus hads superiority in growth.
