毛竹（Phyllostachys edulis）入侵邻近森林的现象越来越普遍。毛竹入侵影响凋落物质量、土壤养分和微生物群落组成。虽然这些影响可能会因入侵地点和森林类型而异，但这还没有被调查。方法我们调查了毛竹入侵对中国3个不同地点阔叶林和针叶林凋落物和土壤中碳（C）和其他主要养分的影响，以及土壤微生物群落组成的磷脂脂肪酸（PLFA）。结果排序表明，入侵对土壤养分的影响，枯落物养分和土壤微生物组成在不同森林类型和地点之间存在差异。入侵持续减少窝C。入侵往往有较大的影响土壤养分在针叶林。除了在一个针叶林网站的细菌群体，入侵对每个土壤group.ConclusionsVariations的方向和幅度的影响，对凋落物性质，土壤性质，和土壤群落之间的社区类型和网站入侵的影响表明，在一个单一的入侵社区对土壤的影响的研究可能无法预测在其他位置的入侵的影响，即使原始社区相似或发生在同一地点。
AimsMoso bamboo (Phyllostachys edulis) invasions into adjacent forests are becoming increasingly common. Moso bamboo invasions affect litter quality, soil nutrients, and microbial community composition. Although these effects likely vary among invaded sites and forest types, this has not been investigated.MethodsWe investigated moso bamboo invasion effects on carbon (C) and other major nutrients of litter and soil, as well as soil microbial community composition determined by phospholipid fatty acids (PLFAs) in broadleaf or coniferous forests at three different sites in China.ResultsOrdinations indicated that the effects of invasions on soil nutrients, litter nutrients, and soil microbial composition each varied among forest types and sites. Invasions consistently decreased litter C. Invasions tended to have larger effects on soil nutrients in coniferous forests. Except for bacterial groups in one coniferous forest site, invasions had positive effects on every soil group.ConclusionsVariations in direction and magnitude of invasion effects on litter properties, soil properties, and soil communities among community types and sites suggest that studies of effects of invasions on soils in a single invaded community may not be able to predict effects of an invasion at other locations, even when the original community is similar or occurs in the same site.
