图2 不同物种(a)或演替阶段(b)灌木存活率的变化。不同字母表示不同灌木物种间存活率差异显著(P < 0.05, Tukey检验)。EuMy: 大果卫矛; ArCr: 朱砂根; LoCh: 檵木; RhIn: 石斑木; EuMu: 格药柃; SyBu: 赤楠; CaCh: 浙江红山茶; GaJa: 栀子; DiMy: 杨梅叶蚊母树; DiBu: 小叶蚊母树; E表示在自然演替群落中, 该灌木出现于演替早期群落; E/L表示在自然演替中该灌木从早期到后期一直存在; I/L表示该灌木在演替中期到演替后期出现; L表示该灌木仅在演替后期出现。

Fig. 2 Survival rates of different shrub species (a) or different successional stages (b). Different letters show statistically significant differences according to a Tukey test at 0.05 level. EuMy, Euonymus myrianthus; ArCr, Ardisia crenata; LoCh, Loropetalum chinense; RhIn, Rhaphiolepis indica; EuMu, Eurya muricata; SyBu, Syzygium buxifolium; CaCh, Camellia chekiangoleosa; GaJa, Gardenia jasminoides; DiMy, Distylium myricoides; DiBu, D. buxifolium. E, Shrub occurs in early-successional stages; E/L, Shrub occurs in all successional stages; I/L, Shrub occurs in intermediate- and late-successional stages; L, Shrub occurs in late-successional stages.
