摘要:

可持续发展已成为全球城市发展核心议题。国内外城市可持续发展研究出现多元化、本地化趋势，但对空间维度关注不足。因此，从空间化研究视角出发，构建“1+3+6”的城市可持续发展评估框架和指标体系，利用多源时空数据、数字画像技术对全国36个主要城市开展可持续发展分维度数字画像和综合评估，识别出3类发展模式。进一步针对城市生态空间、存量空间与“高密强”空间形态等重点场景，拓展以城市可持续发展为目标的专项评估体系和方法，结合对国内城市的实证评估，探讨不同场景的空间优化重点，为面向可持续发展目标的城市规划、建设、治理提供研究支撑，推动可持续发展目标与城市更新及空间治理的深度结合。

Abstract:

Sustainable development has become a central issue in global urban development. While research on urban sustainability, both domestically and internationally, has shown trends of diversification and identifies, there remains a notable lack of sufficient attention to the spatial dimension. The paper constructs a "1+3+6" urban sustainability assessment framework and indicator system from a spatial research perspective. Leveraging multi-source spatiotemporal data and digital portrait technology, the paper conducts a multidimensional digital characterization and comprehensive evaluation of 36 major cities across China, and identifying three distinct urban development patterns. Furthermore, the paper expands specialized assessment frameworks and develops tailored indicator sets and analytical methods that foreground sustainability objectives, including urban ecological spaces, built-up space and high-density-intensive spatial forms to advance urban sustainability objectives. Through empirical assessments conducted on a sample of Chinese cities, the paper examines scenario-specific spatial optimization priorities for different urban settings and provides methodological support for sustainability-oriented urban planning, construction, and governance, while facilitating deeper integration of Sustainable Development Goals (SDGs) with the practices of urban regeneration and spatial governance. The paper not only broadens the perspective of urban sustainability research but also provides actionable insights for evidence-based policy formulation and technical methodologies in urban spatial optimization, contributing to both academic discourse and practical advancements in urban sustainable development
