以河北雾灵山蒙古栎林为研究对象,利用混交度、大小比和角尺度3个空间结构参数分析了蒙古栎天然林空间结构特征。结果表明:蒙古栎种群密度和断面积占有优势,蒙古栎林平均混交度为0.253,蒙古栎林空间配置简单,林分混交度较低;蒙古栎种群和核桃楸种群以优势和亚优势为主,分别占总林分的57%和64%;在角尺度研究中,相对空间结构单元而言,该林分空间分布格局为聚集分布。在对林分以森林生态系统健康为前提的经营时,应以森林群落自然生长和演替过程为依据。
Taking the Quercus mongolica forest in Wuling Mountain, Hebei Province as the research object, the spatial structure characteristics of natural forests in Quercus mongolica were analyzed by using the three spatial structure parameters of mixing degree, size ratio and angle scale. The results showed that the density and area of Quercus mongolica dominated. The average mingled degree of Quercus mongolica was 0.253. The spatial distribution of Quercus mongolica was simple and the mixed degree of forest was low. The Quercus mongolica population and Juglans mandshurica population were dominated by dominant and sub dominant , Accounting for 57% and 64% of the total stand, respectively. In the study of the angle scale, the spatial distribution pattern of the stand was clustered and distributed relative to the spatial structure unit. In the management of forest ecosystems based on the premise of the forest should be based on the natural growth and succession process as the basis.
