图4. 华北地区灌丛灌木层和草本层的物种丰富度(平均值±标准误差)。A, 所有群落草本层和灌木层物种丰富度之间的差异。B, 同一结构层不同植被型之间的差异。用t检验分析整体的差异, 用单因素方差分析检验不同植被型之间的差异。柱形上方不同字母代表相应处理之间在5%水平有显著性差异。a, 竹灌丛; b, 落叶灌丛; c, 灌丛荒漠; d, 常绿针叶灌丛; e, 常绿革叶灌丛。

Fig. 4. Species richness of shrub species and herb species of shrubland in North China (mean ± SE). A, Differences of species richness between herb and shrub species for all communities. B, Differences among vegetation types. Differences between herb and shrub species for all communities was texted by t test and differences among vegetation types were tested using a one-way ANOVA with a Tukey post hoc test of significance. Significance different at p < 0.05 was indicated by different letters. a, bamboo thickets; b, deciduous thickets; c, desert thickets; d, evergreen needle-leaved thickets; e, evergreen leather-leaved thickets.
