外来和本地植物的入侵都会对生态系统产生深远的影响。虽然许多研究调查了外来植物入侵对土壤性质的影响，但相对较少的研究测试了本土植物入侵对土壤微生物群落的影响。此外，我们对本土植物入侵对凋落物微生物群落的影响知之甚少。在中国南方亚热带森林中，对毛竹（Phyllostachys edulis (Carriere) J. Houzeau）入侵3个阶段（未入侵、中度入侵和重度入侵）的凋落物和3个森林沙地表层土壤进行了采样。我们测量了凋落物和/或土壤中的化学性质（C、N、P、Mg、Al、K、Ca、Mn、Cu和Zn的浓度，以及纤维素和木质素的浓度）和微生物群落。总体而言，竹林入侵降低了凋落物和土壤中元素含量，降低了总微生物丰度和多样性。单独考虑细菌和真菌，竹林入侵降低了凋落物和土壤中真菌的多样性，但对细菌的多样性影响不大，说明真菌对竹林入侵的敏感性和脆弱性高于细菌。本文认为，原生毛竹入侵亚热带森林可能导致凋落物-土壤系统发生复杂的生物地球化学过程，通过影响微生物群落，从而影响凋落物分解和养分循环，从而威胁当地森林生态系统。
Both exotic and native plant invasions can have profound impacts on ecosystems. While many studies have examined the effects of exotic plant invasions on soil properties, relatively few have tested the effects of native plant invasions on soil microbial communities. Furthermore, we know little about the effects of native plant invasions on microbial communities in litter. In subtropical forests in southern China, we sampled litter at three decomposition stages and top soil in three forest sands representing three stages of the invasion (not invaded, moderately and heavily invaded) by the Moso bamboo (Phyllostachys edulis (Carriere) J. Houzeau), a native species in China. We measured chemical properties (concentrations of C, N, P, Mg, Al, K, Ca, Mn, Cu, and Zn, and concentrations of cellulose and lignin) and microbial communities in litter and/or soil. The bamboo invasion, in general, decreased the element concentrations in litter and soil and also decreased total microbial abundance and diversity. Considering bacteria and fungi separately, the bamboo invasion decreased fungal diversity in litter and soil, but had little impact on bacterial diversity, suggesting that fungi are more sensitive and vulnerable to the bamboo invasion than bacteria. We conclude that native Moso bamboo invasions into subtropical forests may lead to a complex biogeochemical process in the litter–soil system, which may threaten local forest ecosystems by affecting microbial communities and, thus, litter decomposition and nutrient cycling.
