| 摘 要： | 应用X2显着性检验公式、Pearson相关系数r公式研究了椴树阔叶红松林群落木本植物种间联结性与相关性,得出乔木层9个和下木层19个显着水平以上的联结种对,并对其结果的生态学意义进行分析,认为种间联结的显着与否,是群落生境差异以及物种生态位重叠与分离的反映,并由此提出群落中生态种组的稳定配置模型.

| Abstract: | In this paper,X2 and Pearson r formulae are used to study the interspecific association and correlation of lime-broad leaved Korean pine forest on northern slope of Changbai Mountain.The results show that there are 9 and 19 pairs of significantly associated species respectively in tree-and shrub layers.It is considered that from the view point of ecological meaning, whether it is significant or not,this association is a reflection of thedistinction of community habitat and the overlapping or seperation of niche width.Based on these results,a stable disposed model on ecological species groups in the community is established. |
