摘要：利用混交度、大小比数和角尺度等三种结构参数,分析了红松阔叶天然林的空间结构。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,得到该种林分主要以中、强度混交为主;用平均角尺度和角尺度分布分析了林木水平分布格局,得到该种林分以随机分布为主等结论。同时还应用大小比数和混交度分析了一些主要树种的空间属性,发现两种参数的结合可以清楚地描述树种的空间属性。
In this paper, three parameters were considered to be the suitable ones to describe stand spatial 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 Korean pine broad leaved forest. When using the distribution and the mean of mingling to analyze the spatial collocation of species in the stands, the authors could conclude that mingling intensity of most stands were middling and the most intensive. Tree position distribution was analyzed by using the mean and the distribution of neighborhood pattern.It was concluded that random distribution was the main spatial characteristics of most stand. After using neighborhood comparison and mingling to analyze spatial characteristic of main species, the authors could also consider that the combination of two parameters could be described the spatial characteristic of species clearly.
