宝天曼天然林空间格局分析
Spatial Structure Analysis of Baotianman Nature Forest
摘要
Abstract
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.关键词
