Abstract

Background: Urban plant diversity is an important component of global biodiversity. Urban plant diversity conservation is one of the targets 6 of the Kunming-Montreal Global Biodiversity Framework. 

Review Results: The characteristics of urban plant diversity based on the functional traits, species composition, species diversity and genetic diversity of urban plants were analyzed. The human factors of urban plant diversity were classified into direct influencing factors and indirect influencing factors. Focusing on the roles of different management bodies, such as the government, the community, and the participation of various parties, in the management of urban plant diversity, as well as the characteristics of different management targets, such as urban parks, urban protected areas, urban wastelands, community green spaces, green roofs, and home gardens, the management measures for urban plant diversity were discussed. 

Recommendations: It is recommended to formulate dynamic management measures to cope with changes in the factors affecting urban plant diversity, strengthen multi-party collaborative management to promote the conservation of urban plant diversity, and construct an urban green space protection network to enhance the value of ecosystem services, while strengthening research on the influencing factors of urban plant diversity and their mutual relations, and the scientific evaluation of urban plant diversity management effectiveness, in order to provide references for the conservation and management of urban plant diversity.

Key words: urban, biodiversity, disturbance, conservation, management
