Abstract：In the face of the complex social relationship network of historical blocks,it is still difficult to protect historical blocks to emphasize humans'core value and achieve sustainable development under the premise of maintaining the characteristics of the historical environment.Conzen's"morphological region"effectively provides a structural understanding of the complex urban morphology,organizes clear spatial patterns,and provides systematic and refined spatial transformation measures for historical blocks.At the epistemological level,this article seeks to integrate the established knowledge of urban morphology with the theory of complex adaptive systems and conceptualize urban morphology as a complex adaptive system consisting of an internal adaptive subject and external spatial form elements.Based on the central principle of a complex adaptive system-whereby adaptability creates complexity-the complexity of the urban morphology system is driven by the adaptive behaviors of the subject in the face of environmental change,thus emphasizing the core value of the adaptive subject.At the methodological level,based on Conzen's urban morphology regionalization method,the morphological complexity factor,subject adaptability factor,and environmental influence factor-which can comprehensively express the constituent elements of urban morphology,fully express the core characteristics of complex adaptability of urban morphology,and completely interpret the human-space-environment relationship-are extracted from the urban morphology of Hui historical blocks in Northwestern China.Three logical standards of"internal subject-external environment-spatial morphology"and a morphological regional quantitative indicator system comprising 13 indicators are constructed.The Muslim Quarter in Xi'an is taken as a typical case.According to the technology route of"planar unit division-morphological region identification-optimization type extraction,"68 planar units are optimized and integrated by second-order cluster analysis,and five types of clusters are identified.Based on this and combined with the building types,it is divided into seven types of morphological regions:modern high-density ethnic commercial area,modern high-density ethnic residential area,modern low-density ethnic commercial and residential area,traditional large-scale commercial area,traditional free-form ethnic commercial and residential area,modern commercial area,and modern regular residential area.The entropy evaluation method and obstacle degree model are applied to identify and extract the main controlling factors affecting the adaptability of each morphological region.The Muslim Quarter is further classified into seven morphological region optimization types:open space optimization area,comprehensive function integration area,featured industry revitalization area,residential service improvement area,ecological restoration and protection area,traditional culture shaping area,and innovative industry development area.The research perspectives,logical ideas,and quantitative analysis methods provide more reliable morphological regionalization results for the control and guidance of Hui historical block space,technical support for refined management,and promote the protection and renewal of ethnic areas.
