摘要：Aims Canadian goldenrod (Solidago canadensis) invasion is degrading the coastal shelterbelt forests of subtropical China, but few studies have quantified the role of this invader in structuring understory plant diversity and soil properties. Methods Understory species richness, Margalef index, Pielow index, community stability index, soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP), C:N ratio, pH, bulk porosity (BP), and aeration porosity (AP) were assessed by deriving three categories of goldenrod invasion in coastal shelterbelt forests of Zhejiang, China, that is, uninvaded, moderately invaded and severely invaded plant communities according to goldenrod coverage. Results Goldenrod invasion was generally associated with significantly decreased understory plant richness and community stability, but increased species evenness. Specifically, moderate invasion was associated with substantially fewer species compared to uninvaded communities, it was also associated with increased SOC, C:N ratio, CEC, and AP but decreased TN. However, severe invasion was only associated with slight additional declines in species richness compared to moderate invasion, but further reduced soil TN, SOC, and CEC. Soil TN and TP were both strongly and positively associated with community stability and understory plant species richness. However, severe invasion decoupled the correlational relationshipes between soil TN and understory community stability. Conclusions Moderate invasion of goldenrod caused reduced plant taxonomic diversity and altered soil nutrients in coastal shelterbelt forests of subtropical China. Severe invasion aggravated the impacts a step further, and decoupled soil TN and understory community stability. These results illuminate the impacts of goldenrod invasion on community structure and soil properties in coastal shelterbelt forests and provide evidence that invasive plants can significantly alter the ecological processes in introduced communities.
