摘要: Abstract Thirty-eight sites, representing a wide range of habitat types in representative urban area Ohio, were sampled for their herbaceous vegetation. Ordination the sites yielded several major axes: an inner city-rural dichotomy, gradient related to soil compaction, and based on nutrient status site. A classification by means two-way indicator species analysis revealed existence three community (residual, managed, ruderal) variety minor subtypes. Many communities, particularly those more ruderal nature. are American analogues plant communities common areas central Europe.
