Comprehensive evaluation of urban resilience based on the perspective of landscape pattern: A case study of Shenyang city

摘要

Urban resilience is a new path for the sustainable development of cities in the future. However, recognizing and quantifying urban resilience is still in the conceptual and exploratory stage. In this study, we present a "scale-density-morphology" resilience framework as well as an index model to investigate the evolution of urban resilience based on theories of landscape ecology and evolutionary resilience. We find that spatial development is a major factor affecting scale resilience; population distribution is significantly related to density resilience; urban growth boundaries and ecological infrastructure are factors for optimizing morphology resilience; and an excellent balance of "scale-density-morphology" fosters the development of resilient urban areas. We give large cities recommendations for developing resilience, including-preventing urban sprawl and controlling the scale of construction land, reducing population and building density to promote low-carbon green production and lifestyles, strengthening ecological networks, and controlling urban growth boundaries, etc. This study hopes to provide a scientifically based spatial guide that could implement resilient urban planning and could serve as a case study for quantitative research on urban resilience.
