图3 我国植物园迁地保护的3类植物物种组成相似性分析; 植物园间成对比较的Bray-Curtis相异指数(左上)和Jaccard相似性系数(右下)分布图, 国家重点保护和特有种类的结果相似, 仅显示受威胁种类的热点分布图; 内嵌的箱线图表示3类植物Bray-Curtis相异指数的分布, 所有分析排除了物种数量≤10的植物园。植物园缩写(X轴和Y轴标签)对应的植物园名称及相关数据见附录1。

Fig. 3 Species similarity for ex situ conserved National Key Protected Wild Plants (NKPWP), threatened species, and species endemic to China. Bray-Curtis dissimilarity index (top left) and Jaccard similarity coefficient (bottom right) and heatmap of pairwise comparisons among botanic gardens (threatened species), the results for NKPWP and species endemic to China are quite similar, maps not showing here; embedded box-plot indicate the distribution of Bray-Curtis dissimilarity index for the three plant groups, all analyses excluded botanic gardens that species numbers ≤10. The full name and related data that corresponding to each garden’s abbreviated code (labels on X and Y-axis) see Appendix 1.
