摘  要：
文章对赛罕乌拉自然保护区蒙古栎(Quercus mongolica)种群的年龄结构、种群空间分布格局、不同龄级的空间分布格局及种间关联性进行研究,对样方内个体定位并测定其树高、胸径等指标,采用年龄大小级划分方法对研究区内蒙古栎个体进行等级划分,使用ADE4对定位数据进行格局分析。结果表明:蒙古栎种群表现为增长型;蒙古栎种群在0~20尺度上呈聚集分布,21~25尺度上呈随机分布;蒙古栎种群的聚集强度随尺度增加而增加,达到一定高峰后随尺度的增加而减弱;蒙古栎种群各龄级间关联性不显著,但龄级Ⅰ与龄级Ⅱ呈显著负相关。

摘  要：
The paper studied the age structure, population spatial distribution pattern, the spatial distribution pattern of different age-class, and the interspecific relationship of Quercus Mongolica in Saihanwula of Inner Mongolia. The individuals within the quadrat were positioned and its indexes like tree height and DBH were measured. Besides, the individuals were classified in the method of age level division and the positioning data were treated in ADE4 for structure analysis.The results showed that Quercus mongolica population had a growth form; It was clustered on the scale of 0~20, and randomly distributed on the scale of 21~25; Its aggregation intensity grew with the increase of the scale, and decreases with the increase of the scale after a certain peak. No significant correlations was found among the populations of different age-classes, but the age-class I and II had significant negative correlation.
