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.

Key words: Lime-broad leaved Korean pine forest, Interspecific association and correlation, Community structvre, comprehensive dust absorption ability, evergreen broad-leaved plant, dust absorption amount, urban greening
