摘要/Abstract

摘要： 在天山西部典型天山云杉林中系统布设监测样方,研究乔灌木层优势种空间结构、天山云杉个体间及其与林下忍冬层空间关联性。结果表明:天山云杉胸径分布呈倒“J”型分布;天山云杉整个种群及不同大小径级空间分布差异较大;忍冬除小尺度上(1~36 m)呈聚集分布外,其它尺度上表现为随机分布;天山云杉和忍冬在1~28 m呈正相关关系,上下层竞争不明显,表现为共生或伴生;天山云杉除幼树和小树外,其它个体之间无显著空间关联性,空间上表现为独立分布特性。旅游、放牧等引起的森林小气候变化导致风干扰增加的可能性存在。

Abstract: Research plot was established in the Picea schrenkiana.var tianschanica forest in Xingjiang,northwest China.The spatial distribution patterns of dominant species of trees,shrub layers and spatial associations between Picea schrenkiana.var tianschanica and understory Lonicera caerulea were analyzed and explored.The results showed that the distribution of DBH of Picea schrenkiana.var tianschanica showed reverse “J” pattern.There were large differences involving spatial distribution among DBH classes.The Lonicera caerulea was almost randomly distributed across all studied scales except for the small scale(1-36 m).There was a positive correlation between Picea schrenkiana.var tianschanica and Lonicera caerulea at scales of 1-28 m.There was no obvious competition between overstorey and understorey and these two layers presented symbiosis or associated.There were no clear spatial associations among tree growth stages of Picea schrenkiana.var tianschanica except for the sapling and small trees.The changes of forest microclimate induced by tourists and grazing can possibly contribute to the increase of wind disturbance.

Key words: Picea schrenkiana.var tianschanica , spatial distribution, spatial associations, West Tianshan in Xingjiang
