- Abstract
[Objectives] The paper was to investigate the garden greenbelt in 30 sample plots such as parks, roads, communities, etc. in Shijiazhuang City. [ Methods] The species, abundance and frequency of weeds in the greenbelt of public gardens were recorded through point-line-surface investigation, and typical plants were sampled. [Results] There were 56 species of alien invasive plants in garden greenbelts of Shijiazhuang City, belonging to44 genera and 20 families. In terms of life form, herbaceous plants were absolutely dominant, accounting for 92.8% of the total. The most alien invasive plants were native to America, accounting for 66.1% of the total. In terms of introduction path, the plants introduced artificially and unintentionally accounted for almost half. The species and quantity of alien invasive plants were related to the size of greenbelt area, the length of the build time of the surveyed plot, the composition structure of greenbelt and the level of green management and protection. There was larger distribution of alien invasive plants in the sample plots with large greenbelt area, long build time, herbaceous-dominated greenbelt and low level of green management and protection. Among the 56 alien invasive plants, 3 plants were toxic. From the perspective of invasiveness, the alien invasive plants in the garden greenbelt of Shijiazhuang City could be divided into 5 levels: invasive alien species of malignant consequences, invasive alien species of severe consequences, invasive alien species of partial consequences, invasive alien species of average consequences, and invasive alien species to be observed. [Conclusions] This study will provide a reference for the prevention and control of alien plant invasion, and lay a foundation for the prevention and control of existing invasive plants.
