摘　　要：当前历史街区的韧性研究主要集中在理论的阐释,而缺少科学、完整的韧性量化实践路径。出于历史街区形态保护的目的,将形态的抵抗力韧性作为形态韧性量化评估的主体。在分析康泽恩城市形态学框架与韧性理论结合具有可行性的基础上,建构了以划分“形态韧性区域”为核心的历史街区形态韧性量化评估方法。评估中采用道路系统连通性、地块模块性、用地功能多样性、建筑肌理稳健性4个形态韧性指标。通过加权叠加获得历史街区的形态韧性区域图,用于反映不同形态类型的韧性强弱。在此基础上根据风貌类型和形态韧性量化结果划分出五类形态韧性管理单元,目标是实现对历史街区形态的精细化保护与管理。Existing research on the resilience of historical blocks mainly focuses on theoretical interpretation but lack a scientific and complete way of quantifying resilience.The morphological resilience of historical blocks includes"resistance","resilience",and"adaptability".For the purpose of protecting the morphology of historical blocks,"resistance"was chosen as the main body of this study's quantitative evaluation of the morphological resilience of historical blocks.According to analysis,it is feasible to combine Conzen's morphology framework with Holling's resilience theory.Therefore,a quantitative evaluation method for the morphological resilience of historical blocks which uses a"morphological resilience region"as the core concept was developed based on the combination of Conzen's morphology framework and Holling's resilience theory.It was applied to the quantitative evaluation of the morphological resilience of historical blocks in the east,west,and south corners of Luoyang City.First,the morphological regions of historical blocks in the east,west,and south corners were divided.Morphological resilience of the historical blocks was quantified by GIS and sDNA technological platforms.Road system connectivity,block modularity,land use functional diversity,and building texture robustness were used as level-1 indicators,and each level-1 indicator contained two level-2 indicators that could be numerically calculated.The weighted superposition of the quantitative results of multiple indicators forms the morphological resilience grid map of historical blocks in the east,south,and west corners.The morphological resilience region which reflects the resilience intensity of different morphological types was acquired by superposition of the resilience grid and Conzen's morphological region framework.The results show that among the seven main morphological types of historical blocks in the east,west,and south corners,the low-resilience area of traditional historical commercial streets,modern linear residential areas,and tradit
