摘要
基于色季拉山长期4 hm2监测样地的调查资料,采用成对相关函数(pair-correlation function)点格局方法,分析了色季拉山观测样地灌木层优势种杯萼忍冬和柳叶忍冬的空间格局及关联性。结果表明:发现两种忍冬都在小尺度上呈显著聚集分布,随着龄级和研究尺度的增加种群聚集强度逐渐减弱,最终趋向于随机分布格局;杯萼忍冬种群和柳叶忍冬种群在小尺度上具有正的关联性。
In this study,based on the investigating materials of a 4 hm2stem-mapping plot,we analyzed spatial distributions of Lonicera inconspicua and L. lanceolate,the dominant species in forest of Segera mountains.Pair-correlation function was used to characterize spatial point patterns of the population and spatial realations between these two species. Two Lonicera Linn. Species of the population were spatially obviously aggregated at the small scales（ 0 ~ 4 m）,and the distribution were more and more random and uniform with the increases of the age and research scale,finally tending to random distribution pattern. Lonicera inconspicua and L. lanceolate were positive related at the small scales.
