Research on the Spatial Form of Traditional Villages from the Perspective of Conzenian Urban Morphology—A Case Study of Fengxi Village in Guizhou

Against the backdrop of rural revitalization, traditional ethnic minority villages in Guizhou face the dual challenges of conservation and development. Existing research has largely focused on macro-scale morphological descriptions, lacking an operational spatial classification method that can directly guide planning and management. To address this gap, this paper takes Fengxi Village in Dejiang County as a case study, integrates Conzenian urban morphology with the concept of “management units”, and proposes a spatial unit classification method for traditional villages based on the overlay analysis of “morphological region + building unit”. First, using Conzenian plan analysis, the study systematically deconstructs land use, road systems, plot combinations, and building types of Fengxi Village to delineate morphological regions. Second, it introduces three evaluation factors—building value, building quality, and building style—and, through quantitative assessment, classifies all 702 buildings in the village into five categories, protection units, repair and improvement units, comprehensive renovation units, demolition and renewal units, and new construction units, with the number and proportion of each category calculated. On this basis, differentiated control guidelines and development strategies are proposed for each unit category. The research shows that this method represents a preliminary attempt to translate “morphological description” into “operational control”, breaking down the relatively macro goal of “integral conservation” into concrete “unit-based control” actions, thereby providing a technical workflow that can be referenced for similar studies on the fine-grained planning and management of traditional villages. The main contribution of this paper is the construction of a systematic technical framework of “morphological analysis–factor evaluation–unit-based control”, and the demonstration of its application at the micro-operational level through the Fengxi Village case study, offering a meaningful complement to the existing research in terms of operationalization.
