图5 岛屿属性、气候与人类影响对木本植物丰富度的影响。(a)常绿阔叶木本; (b)落叶阔叶木本; (c)常绿阔叶木本占总阔叶木本植物的比率。直线代表95%置信区间; 虚线左侧为负相关, 右侧为正相关; 三角形代表标准化参数的估计值显著, 点则不显著。岛屿属性、气候、人类影响、变量间的交互变量分别用绿色、蓝色、紫色和红色表示。变量缩写同图3。纵轴上交互项之间用冒号表示。

Fig. 5 Effects of island physical characteristics, climate and human influence on woody plant richness. (a) Evergreen broad-leaved woody plants; (b) Deciduous broad-leaved woody plants; and (c) The ratio of evergreen broad-leaved woody plant richness to all broad-leaved woody plant richness. The straight line represents the 95% confidence interval. The left side of the vertical dashed line indicates negative correlations, while the right for positive correlations. The triangles indicate statistically significant estimates of standardized coefficients, and the dot points show the non-significant ones. Island characteristics, climate, human influence and their interactions are represented in green, blue, purple and red, respectively. Variable abbreviations are the same in Fig. 3. Interaction variables are separated by colons.
