摘要

In order to master the natural geographical characteristics of different gradations forest in Daliangzihe National Forest Park ,the geographical elements of families and genera of tree ,shrub and grass were classified with field and sample plot surveys .The results showed that temperate zone was main distribution area of tree , shrub and grass ,and north temperate zone was the largest type ,including 247 species 116 genera .%为掌握大亮子河国家森林公园不同层次森林植物的自然地理特征，利用实地踏查与样方调查法对乔、灌、草不同层次植物进行了科和属的地理成分类型划分。结果表明：乔灌草各层植物区系均是以温带分布地理成分为主，以北温带分布的植物属数和种数最多，共116属247种。
