| 摘 要： | 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。

| Abstract: | With Quercus mongolica in Hebei Wuling mountain as study object and by using mingling degree,neighborhood comparison and uniform angle index,this paper analyzed the spatial structural characteristics of Quercusm ongolica forest in the Reserve.The results showed that Q.m ongolica had the obvious advantage in population density and basal area.The average mingling degree of the forest was 0.299,indicating the simple spatial allocation and poor mixing of different tree species in this plantation.In the spatial structural units,Q.mongolica and J.mandshurica populations were dominant and sub-dominant,accounting for 57% and 64% of the total plants of the populations;As for uniform angle index and the spatial structure units,the spatial pattern of the stands was of aggregative distribution.Stand management in term of the forest ecosystem health should be based on community-based natural succession. |
