摘要对祁连山东段哈溪林区黄草岭神树沟顶、哈溪林区黄草岭大阴屲山峡及友爱十队不同海拔高度地区灌木和草本植物的分布数量、高度和覆盖度进行了调查与研究，分析了青海云杉林下灌木和草本植物的分布和生长状况，结果表明：温度为影响祁连山东段哈溪林区青海云杉林下灌木和草本植物生长的主要因子,随着海拔的降低，青海云杉林下灌木和草本植物的分布均有显著性的差异。

AbstractNumber, height & coverage of distribution in shrubs and herbs with different altitude were investigated in the top of Shenshugou & Dayinwa Gorge of Huangcao Mountain, Youai tenth headquarters of Haxi Forest Zone in eastern Qilian Mountain. Distribution and growth of shrubs and herbs under forest of Picea crassifolia were analyzed. Result shows that the temperature is main factors of influencing shrubs and herbs for Picea crassifolia in Haxi Forest Region of eastern Qilian Mountains;distribution of shrubs and herbs under forest of Picea crassifolia have significant differences with the decrease of altitude.
