图2. 凋落物分解过程中叶际微生物和土壤微生物的相对变化示意图(改自Fanin等(2021))。在叶片掉落前夕(①), 叶际微生物快速生长, 然后掉落在地表(②); 在凋落物分解早期(③), 叶际微生物和土壤微生物共存; 在凋落物分解中晚期(④), 土壤微生物占主导。

Fig. 2. Schematic diagram of the relative changes of phyllosphere microbes and soil microbes during litter decomposition (adapted from Fanin et al. (2021)). On the eve of leaf drop (①), phyllosphere microbes grew and colonized rapidly and then leaf litter fell to the ground (②); in the early stage of litter decomposition (③), phyllosphere microbes and soil microbes coexisted; in the middle and late stages of litter decomposition (④), soil microbes dominated.
