Relationship between plant diversity and community stability and invasibility in the heterogeneous landscape of urban habitats undergoing Solidago canadensis invasion

Background Solidago canadensis has become an invasive species in Chinese cities. Little progress has been made in understanding the relationship between the plant taxonomic diversity and community stability and invasibility of local plant communities during S. canadensis invasion, especially in heterogeneous landscapes. Progress in understanding the relationship between the key functional traits of S. canadensis and its invasion intensity and competitive advantage, especially in heterogeneous landscapes, is also currently limited.
