Abstract

Abstract

In order to understand the status of invasive plants in Nanjing Botanical Garden Memorial Sun Yat-Sen, the species, origin, life form, frequency and damage of alien invasive plants were surveyed through routing and sampling. The results showed that there were 65 invasive plants in the botanical garden area; Compositae constituted the largest proportion, accounting for 32.31% of the total, followed by graminaceous plants, accounting for 9.23% of the total. Among the invasive plants, 7 species have caused serious harm, 44 species were introduced from America (the largest point of origin), and most were annual herbs (46.15%). Wasteland and meadows under poor management are the most vulnerable habitat types. The invasion of some species has correlation with the introduction of new plants in the botanical garden.
