Abstract:

Background & Aim: As a critical research area under the framework of the Convention on Biological Diversity (CBD), urban green spaces play a key role in maintaining the ecological stability of cities and improving the quality of life of residents. However, the compound pressures of habitat fragmentation, invasive alien species and environmental pollution brought about by large-scale global urban expansion have made the conservation of biodiversity in urban green spaces an urgent issue in global ecological governance. 

Progress: This paper focuses on the biodiversity of urban green space under high intensity artificial intervention, systematically analyzes its conceptual connotation and research scope, reviews the research progress in monitoring technology, functional synergy, landscape optimization and management strategy, and points out the shortcomings of the existing research and the future direction. It is found that urban green space has an irreplaceable role in enhancing the resilience of ecosystem services, promoting the migration and diffusion of species, and improving climate resilience, and its biodiversity conservation needs to take into account the restoration of ecological connectivity and multifunctional synergy optimization. However, the current research still faces bottlenecks such as fragmentation of monitoring technology system, disconnection of cross-scale planning and lagging governance mechanism. In the future, it is necessary to build an intelligent monitoring system and a comprehensive database, develop multi-objective synergistic models, promote biodiversity-oriented green space system planning, and innovate a multifaceted governance mechanism. 

Prospects: Through interdisciplinary integration and international cooperation, the conservation of urban green space biodiversity will be deeply embedded in the governance of land space, and the synergistic path of urbanization and biodiversity conservation will be explored, so as to provide a scalable ecological restoration plan for the realization of the global “ 3030” goal, and provide a scientific decision-making paradigm for the sustainable symbiosis of urban ecosystems in the context of the Anthropocene.
