Abstract:Due to the rapid development of urbanization and the continuous change of global climate, cities are faced with seriously ecological and environmental challenges. How to improve the resilience of the ecosystem and enhance the ability of resisting internal and external interference of cities are crucial to regional sustainable development. Ecological resilience represents the ability of ecosystem to recover to a stable state after being disturbed. With the increasing concern for sustainable development, ecological resilience has become an important issue. Green space is important for coordinating environment protection and urban development, and is also the significant carrier of ecological resilience. Green space with complete structure and perfect functions can help cities to cope with the environmental risks, improving the ecological resilience of cities. This paper reviewed the research content of green space from the multidisciplinary perspective, discussed the research progress of spatiotemporal evolution characteristics, driving mechanism, and scenario simulation of green space. Then, based on the review of the development process of ecological resilience theory and related research progress, the green space optimization strategies from the perspective of ecological resilience were summarized. The optimization strategies were explored on macroscopic, middle, and microscopic three aspects. Macroscopic researches involved the overall structure and service capacity of green space at the regional scale such as urban agglomerations and watersheds. The middle scale researches were concerned with the improvement of the quality and anti-interference ability of urban green space. The studies were based on the analysis of urban green space network optimization, green space land demand calculation, greenway system classification planning and green infrastructure configuration. Microscopic researches focused on the design guidance of specific green spaces like park and square. Reduce the vulnerability of green space by improving the capacity of stormwater management, improving the quality of habitats, and increasing biodiversity. This paper also explored the integration of ecological resilience study and green space system planning. We tried to construct a mechanism of strategy-feedback interaction between Green Space Planning and ecological resilience analysis. Further, the methods of combining the Territorial Spatial Planning with the ecological resilience analysis were discussed. The analysis could be integrated into the multi scale and multi type plannings, providing scientific support for Territorial Spatial Planning. Finally, this paper proposed three advices for the further researches in China:improving the multi-level ecological resilience evaluation system, strengthening the overall analysis of social-ecosystem, exploring the division treatment of green space with different ecological resilience from the perspective of thresholds.
