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。

The preferred habitat types of Cabot's tragopan in each season were: evergreen-deciduous forest and the broadleaf strips in spring; the broadleaf strips and shrubs in summer and evergreen-deciduous forest and shrubs in autumn; the habitat selected in winter was the same as that in spring but were more relied on by the birds.

黄腹角雉所偏好的栖息地类型，在春季为常绿阔叶--落叶混交林和人工针叶林中的阔叶林条带；夏季为阔叶林条带和灌草丛；秋季为常绿阔叶--落叶混交林和灌草丛；冬季与春季相同，但对这两种类型栖息地的依赖性比春季更强。

These pollen maps show significant vegetation changes during the past 10 000 years in the current forest regions of Northeast China, with the early Holocene characterized by the widely distributed Birch, the mid-Holocene by the development of temperate deciduous forest mainly consisting of Quercus and Ulmus, and the late Holocene by the marked increase in Pinus abun dance and the development of temperate mixed conifer and deciduous forest.

花粉图展示了东北地区植被演化的主要特征。桦树在全新世初期遍布从三江平原到辽东半岛南端的东北东部地区，在森林中占据绝对优势地位；榆属和栎属等阔叶乔木在早中全新世的大部分时间内是东部森林中的主要种类；在大约5kaBP以后，松属在东北现在的森林地区开始增加，云、冷杉属也表现出较明显扩大，中北部地区的森林覆盖度可能比原来增大了。

The increased NPP was primarily led by an advanced growing season for broadleaf evergreen forest, needle_leaf evergreen forest, and needle_leaf deciduous forest, whilst that was mainly due to enhanced vegetation activity during growing season for broadleaf deciduous forest, broadleaf and needle_leaf mixed forest, broadleaf trees with groundcover, perennial grasslands, broadleaf shrubs with grasslands, tundra, desert, and cultivation.

常绿阔叶林、常绿针叶林和落叶针叶林NPP的增加主要由生长季节的提前所致，而落叶阔叶林、针阔混交林、矮林灌丛、温带草原及草甸、稀树草原、高寒植被、荒漠以及人工植被NPP的增加主要来自生长季生长加速的贡献。
