摘要
天山云杉林是是天山山地主要的地带性森林植被,是中亚和亚洲中部山地的特有树种,在我国仅见于新疆。采用网格定位法,调查了新疆西部天山云杉林6 hm2样地中DBH≥1 cm的所有木本植物,并对样地内的草本植物采用网格法进行随机取样调查。结果表明:调查样地内天山云杉林群落物种组成简单,物种区系在属的水平上以温带成分为主;群落优势种明显,是以天山云杉为主的单优植物群落,优势种天山云杉的径级分布为正态分布。
Picea screnkiana var.tianschanica is a tree unique to the mountain in central Asia,and is only found in Xinjiang.P.screnkiana var.tianschanica forest is the typical vegetation in Tianshan Mountain.All of the woody plants with more than or equal to 1 cm DBH and the herbaceous plants in 6 hm2 plot of P.screnkiana var.tianschanica are investigated by grid locating and random grid sampling,respectively.The results show that P.screnkiana var.tianschanica is the main priority of a single plant community,whose diameter is in a normal distribution.
