【摘要】 历史文化街区展现着城市的传统风貌，但同时也面临着现代化、全球化以及快速城市化的挑战。文章以沈阳市中山路历史文化街区为研究对象，指出单纯依赖“输血”机制的保护难以为继。该街区主要承载居住功能，沿街小型商户众多，传统街区模式难以满足发展需求。因此，文章提出微更新保护设计策略，通过小规模、渐进式改造，如修复历史脉络、重构物质空间形态及重新配置功能等，实现历史文化与现代生活的和谐共生。此策略旨在延续街区的历史空间肌理，保护传统风貌，同时增强街区活力与可持续性，为历史文化街区的保护与更新提供新思路与方法。更多还原

【Abstract】 Historic and cultural districts embody the traditional features of cities, yet they face challenges posed by modernization, globalization, and rapid urbanization. Taking the historic and cultural district of Zhongshan Road in Shenyang as the research object, this paper points out that relying solely on the "transfusion" mechanism for preservation is unsustainable. This district primarily serves residential functions, with small businesses lining the streets, and the traditional mode of districts has become difficult to match the demands of modern society. Therefore, this paper proposes a micro-renewal preservation design strategy, employing small-scale, gradual renovations such as restoring historical development, reconstructing physical spatial forms, and reallocating district functions, to achieve harmonious coexistence between historical culture and modern life. This strategy aims to continue the historical spatial texture of the district, preserve and highlight traditional features, while enhancing its vitality and sustainability,providing new ideas and methods for the preservation and renewal of historic and cultural districts.更多还原
