长白山北坡椴树阔叶红松林群落木本植物种间联结性与相关性研究

应用Ｘ２显著性检验公式、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个显著水平以上的联结种对，并对其结果的生态学意义进行分析，认为种间联结的显著与否，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．

Interspecific association and correlation of lime-broad leaved Korean pine forest on the northern slope of Changbai Mountain.

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.
