摘　　要：通过对白龙江上游水源涵养林植被分布及恢复情况的调查研究,得出本区域内植被主要分布在海拔3500m以下,植被多样性随着海拔的升高表现为低一高—低,在海拔2 000～3 000 m范围内植被的种类、多样性及群落的复杂结构均达到最高;与人工林相比,天然林、天然次生林及其林下植被生长良好,灌草盖度高,林下灌木种类多;在同一海拔范围内,阴坡灌草种类及盖度明显大于阳坡.Based on the investigation and study about the vegetation distribution and recovery of water conservation forests in Bailong River upstream, the vegetation mainly distributed at an altitude of 3 500 m below, the diversity of vegetation performance for low to high to low with the increase of altitude, the species and diversity and the complex structure of community reach highest in 2 000-3 000 m range; compared with the plantation, the undergrowth of natural forests and natural secondary forest grew well, the coverage of shrub and grass are high, the species of understory shrub is rich; within the same altitude, the species and coverage of shrub and grass grow in shady slope are significantly greater than sunny slope.
