Abstract: To explore the relationship between habitat types and community invasibility in relation to the phylogenetic characteristics of herbaceous plant communities (phylogenetic diversity, phylogenetic relationships, and phylogenetic structure), a survey was conducted in three habitats (forest, wetland, and grassland) across eight urban parks in Beijing. Phylogenetic diversity analysis and regression analysis were performed, comparing the differences in community invasibility across the habitats and analyzing the influence of phylogenetic traits on the invasibility of different habitats. The results showed that the invasibility of the community was the highest in the forest habitat and the lowest in the grassland habitat. In the forest habitat, the invasibility of the community was significantly correlated with various phylogenetic traits, with the net phylogenetic relatedness index of native plants showing a strong negative effect on community invasibility. In the wetland habitat, the community invasibility was significantly related to multiple phylogenetic traits, and phylogenetic diversity had the most pronounced suppressive effect on invasibility. In the grassland habitat, the net phylogenetic relatedness index and the most recent taxonomic unit index of native herbaceous plant communities with a single phylogenetic trait both showed significant negative correlations with community invasibility. However, the results of a comprehensive multiple regression analysis indicated that there was no significant relationship between community invasibility and phylogenetic traits in the grassland habitat. Overall, the invasibility of communities in urban parks was significantly associated with their phylogenetic characteristics. In view of the problem of urban plant invasion, it is necessary to formulate differentiated prevention and control strategies according to different habitat types, integrate multi-dimensional research, technology application and social participation, and establish a more comprehensive management framework for invasive plants in urban parks.
