| 图2 乔木层(a)、灌木层(b)、草本层(c) beta多样性(Btotal)及其物种周转组分(Repl)和物种多度差异组分(AbDiff)三角图。图中每个黑点表示一个样方对, 其位置由物种组成相似性(S = 1 - Btotal)、Repl和AbDiff决定, 三者之和等于1。灰色大点表示平均值。 |
| Fig. 2 Triangle figures for arbor (a), shrub (b), and herb (c) of plant beta diversity (Btotal), and its components of species turnover (Repl) and abundance differences (AbDiff). Each black dot represents a pair of sites. Their positions were determined by a triplet of values from the species composition similarity (S = 1 - Btotal), Repl, and AbDiff; each triplet sums to 1. The larger grey dots represent the mean values. |
