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。
In the typical Tianshan spruce forest in western Tianshan, monitoring plots were laid to study the spatial structure of the dominant species in the shrub and shrub layer, the spatial correlation between individual individuals of Picea crassifolia and its subtropical layer. The results showed that the DBH distribution of Tianshan Mountains was inverted J-shaped distribution. The spatial distribution of Picea crassifolia’s entire population and different size classes was quite different. On the small scale (1 ~ 36 m) Other scales showed random distribution. There was a positive correlation between Spruce Tianshan and honeysuckle in the range of 1 ~ 28 m. The competition between the upper and lower layers was not obvious, which showed symbiosis or companion. Among the individuals of Tianshan spruce, except the young and young trees, Significant spatial correlation, the spatial performance of an independent distribution. Climate microclimatic changes caused by tourism, grazing and other causes the possibility of increased wind disturbance.
