The results showed that: (1) Hangzhou Botanical Garden has conserved a total of 143 species of rare and endangered plants from 91 genera and 49 families of rare and endangered plants, all of which are Chinese key protected wild plants, including 34 first-class protected plants and 109 second-class protected plants. Among them, 39 species were listed in the IUCN Red List threatened species. They could be divided into 5 categories, among which 25 belong with the Critically Endangered (CR) species, accounting for 17.48%, 39 belong with the Endangered (EN) species, accounting for 27.27%, 52 belong with the Vulnerable (VU) species, accounting for 36.36%, 10 belong with Near Threatened species, accounting for 6.99%, 15 belong with the Least Concern (LC) species, accounting for 10.49%, whereas 2 belong with the Data Deficiency (DD) species which accounts for 1.40%. (2) In terms of garden applications, the major of plant growth types are trees, accounting for 44.76%, followed by perennial herbs, accounting for 32.17%;foliage plants (87.41%) and ornamental plants (86.71%) account for the highest proportions;rare and endangered plants are used in various forms. Finally, the article puts forward suggestions and strategies for the protection, promotion and application of rare and endangered plants in Hangzhou Botanical Garden: (1) Improve infrastructure and improve species adaptability;(2) Expand resource collection to ensure genetic diversity;(3) Strengthen monitoring and management to grasp dynamic changes;(4) Build an evaluation system to select excellent species;(5) Strengthen introduction and domestication, carry out Resource expansion;(6) Innovate application forms to show the charm of plants.展开更多
