According to the life form of species and their roles in communities, 6 species groups are used to do ordination analysis and environmental interpretation. The result suggests that:①Despite the strong man-made disturbance at lower altitude sites, the number and character of evergreen species show an change along the altitude gradient.②The rare and endangered species concentrated at two sectors along altitude gradient, corresponding to the upper and lower borders of the mountain mixed forest belt of evergreen and deciduous broad-leaved species.③The pioneer tree species concentrated on the middle and upper positions at lower elevation.④The deciduous accompany tree species show a great diversity on middle and lower position at middle and higher elevation.⑤Coniferous species differentiate along elevation and local topographical gradient.⑥Deciduous species in Quercus, Castanea, Fagus, Carpinus genus as well as coniferous species play primary community-constructing roles at different topographical position at Dalaoling region.
根据物种生活型及其在植物群落中的地位，分6个种组进行排序和环境解释，表明：①尽管低海拔地段受到强烈人为干扰，常绿种类仍显示了数量和性质沿海拔梯度的变化；②珍稀物种在海拔梯度上形成两个相对集中的区段，大致对应于山地常绿落叶阔叶混交林带的上下边缘；③先锋树种在中低海拔的中上坡位富集；④在中、高海拔的中低坡位，落叶的乔木伴生种显示了极大的多样性；⑤为数不多的针叶树种在海拔和局部地形梯度上也有明确分异；⑥它们和落叶的栎、栗、水青冈、鹅耳枥属物种在大老岭地区不同地形部位的植被中起着主要的建群作用。

In this study, 22 ground field plots were set up in the leucocephala invasion areas. Important value index and Two-way indicator species analysis were used. According to the levels of invasion of leucocephala that can be divided into three forest types: Vitex negundo-Leucaena leuococephala type, Acacia confuse-Leucaena leuococephala type and Murraya paniculata-Leucaena leuococephala type. The companion plants are Acacia confuse, Vitex negundo, Bridelia monoica, and Melanolepis multiglandulosa.
