图2 云南香格里拉亚高山寒温性针叶林20 hm2动态监测样地中亚乔木层和灌木层优势种的空间分布格局。A, 红棕杜鹃。B, 西南花楸。C, 唐古特忍冬。D, 云南双盾木。黑色实线表示单变量成对相关函数g(r)的函数值, 红色虚线表示单变量成对相关函数g(r)的期望值, 灰色阴影部分表示99%的置信区间。地图中绿色表示低海拔, 红色表示高海拔。p值为拟合优度检验结果。

Fig. 2 Spatial distribution pattern of dominant species in the subtree layer and shrub layer in the 20 hm2 dynamics plot of subalpine cold-temperate coniferous forest in Shangri-La, Yunnan. A, Rhododendron rubiginosum. B, Sorbus rehderiana. C, Lonicera tangutica. D, Dipelta yunnanensis. Solid black lines represent the value of the univariate pair-correlation g(r) function, the dashed red lines represent the expected value of the univariate pair-correlation g(r) function, and the gray shaded parts represent the 99% confidence interval. Green on the map indicates low altitudes and red indicates high altitudes. The p-value is the goodness of fit test result.
