在现代花粉集合和高度的植被带之间的量的关系为在山区域的 paleovegetation 的重建是关键的。70 件表层土样品上的现代花粉分析与 50 m 的举起间隔在东方西藏的高原在 Gongga 山的东方斜坡上越过高度的横断(11004500 m ) 被进行。沿着横断的主要花粉类型的分布显示了在 Pinus 花粉和举起之间的弱关联。Picea 的分布并且受苦花粉(2%8% 的百分比和) 能相当在这个区域显示 27003700 m，以及亚高山带的黑暗具球果的森林和树带界线的举起范围。Ericaceae， Cupressaceae 和 Cyperaceae 的高山的类型的高百分比间隔被相关到高山的灌木草地和高山的草地统治的高举起的区域(37004500 m ) 。Gongga 山的东方斜坡上的七条高度的植被带由在现代花粉集合上进行的判别式分析是明确的，作为由现代类似物的概率的高价值思考了。大多数现代花粉集合(88.5%) 为在他们的采样地点的植被类型是典型的。因此，在越过高度的横断的现代花粉集合和植被之间的关系能在东方西藏的高原的山区域基于判别式分析被用于 paleovegetation 变化的量的重建。

英文摘要：

Quantitative relationship between modern pollen assemblage and altitudinal vegetation belt is crucial for the reconstruction of paleovegetation in the mountain regions.Modern pollen analysis on 70 topsoil samples was conducted across an altitudinal transect（1100-4500 m） on the eastern slope of Gongga Mountain in the eastern Tibetan Plateau with an elevation interval of 50 m.Distributions of major pollen types along the transect indicated a weak correlation between Pinus pollen and the elevation.Distributions of Picea and Abies pollen（percentage sum of 2%-8%） could fairly indicate the elevation range of 2700-3700 m,as well as the subalpine dark coniferous forest and the timberline in the region.High percentage intervals of alpine types of Ericaceae,Cupressaceae and Cyperaceae were correlated to the high-elevation regions（3700-4500 m） dominated by alpine shrub meadow and alpine meadow.Seven altitudinal vegetation belts on the eastern slope of Gongga Mountain were well defined by discriminant analysis conducted on the modern pollen assemblages,as reflected by high values of probability of modern analog.Most of the modern pollen assemblages（88.5%） were typical for the vegetation types at their sampling locations.Thus,the relationship between the modern pollen assemblages and vegetation across the altitudinal transect based on discriminant analysis can be applied to the quantitative reconstruction of paleovegetation changes in the mountain regions of the eastern Tibetan Plateau.
