图5 滇中高原半湿润常绿阔叶林样地物种组成的非度量多维尺度分析(NMDS)排序图。图中实心圆表示野外调查数据; 三角形表示《云南植被》数据; 不同颜色代表不同的群落类型, 实心圆和三角的大小表示样地所在斑块面积的大小。A: 高山栲群落; B: 元江栲群落; C: 高山栲 + 元江栲群落或元江栲 + 白穗石栎群落; D: 元江栲+滇石栎群落; E: 滇青冈群落; F: 高山栲 + 滇油杉-云南含笑群落; G: 高山栲 + 滇油杉群落。

Fig. 5 Non-metric multidimensional scaling (NMDS) ordination diagram of the plots of semi-humid evergreen broad-leaved forests in the Central Yunnan Plateau. The color of the circles (data from field sampling) and triangles (data from Vegetation of Yunnan) in the figure represents different community types, and the size of the icon represents the size class of the patch area where the plot is located. A, Ass. Castanopsis delavayi; B, Ass. C. orthacantha; C, Ass. C. delavayi + C. orthacantha or Ass. C. orthacantha + Lithocarpus craibianus; D, Ass. C. orthacantha + L. dealbatus; E, Ass. Cyclobalanopsis glaucoides; F, Ass. C. delavayi + Keteleeria evelyniana-Michelia yunnanensis; G, Ass. C. delavayi + K. evelyniana.
