Multivariate Associations between Environmental Variables and the Invasion of Alien Plants in Floodplain Waterfront Parklands along the Nakdong River

摘要: Riparian zones are more susceptible to invasions of alien plant species than other ecosystems. Plant invasion is determined by multiple interacting factors, such as the characteristics invasive plants, climate, disturbance patterns, and competition with native plants. To investigate interactions environmental factors regard an species, we considered a range including topography, accessibility (or anthropogenic disturbances), aquatic land-use history in 115 waterfront parklands along Nakdong River. The parks were constricted after river restoration project from 2009 2012. most common plants Oenothera odorata, Erigeron annuus, Coreopsis lanceolate our study areas. Alien areas negatively associated areas, which indicated that dominant mainly occur drier uplands area under study. Accessibility disturbances) had positive effect on proportion species. We assumed frequent human visits disturbances may increase potential for diverse In addition, historic agricultural positively Our results suggest depend degree accessibility, historical patterns.
