摘要:

在城市更新与健康中国战略背景下，街道的健康功能优化成为提升街区品质、促进公共健康的关键路径。立足《城市更新“十五五”规划》与存量更新 语境，再定位街道在健康城市中的角色，结合国际共识与本土探索，梳理健康街道从原则倡导、机制分析到本土化实践建设的演进脉络，指出现有理论在机制解析 和精准适配实践方面面临的挑战；揭示街道环境通过基础保障(环境暴露、安全通行)、行为激活(身体活动、食物获取)、价值引导(心智发展、社会包容)3个层次 6个维度影响公共健康的作用机制，并构建健康街道的“环境-感知-行为”三元互动模型。总结形成健康街道价值评估与诊断框架，围绕“环境要素-中介路径-健 康价值-监测反馈”的逻辑，探讨健康街道从空间要素识别走向健康价值判断和更新行动反馈的实施方法。结果表明，健康街道是一项整合环境质量、社会活力、经 济可持续性与公共生活品质的城市更新方法，基于韧性、包容和创新导向，使街道真正成为所有人的健康基础设施。

Abstract:

Against the backdrop of China's urban development entering a stage of optimizing existing urban built environments, urban renewal and urban construction are increasingly emphasizing health-value-oriented space making and governance, thereby advancing the Healthy City strategy. As a basic component of urban space and the direct setting of residents' everyday health behaviors, streets are indispensable to healthy cities and constitute an important functional carrier for translating health goals into spatial practice. In China, however, the theoretical development and practical application of healthy streets still face challenges. The interaction mechanisms among human perception, behavior, and environment remain insufficiently clarified, while assessment methods and design strategies still require optimization to adapt to diverse built environments and changing resident needs. On this basis, this paper reviews relevant research and practical explorations, and reveals the mechanism through which street environments affect public health through three levels and six dimensions: environmental exposure and safe mobility at the basic support level, physical activity and food access at the behavior activation level, and mental and cognitive development and social inclusion at the value guidance level. The paper further constructs an environment-perception-behavior triadic interaction model for healthy streets, interpreting healthy streets as a dynamic process and positioning the six dimensions within this model. For healthy streets to move from theoretical advocacy toward design practice, health goals need to be translated into assessment items that can be identified, judged, and fed back into street-space renewal. Therefore, the paper proposes a value assessment and diagnostic framework following the logic of environmental elements, mediating pathways, health values, and monitoring feedback. Through cases such as Urban Renewal of Huangyan Waterfront - Fostering Connection and SIU KAI FONG, the paper analyzes the common strategies and value orientations of healthy streets in practical projects, and examines their multiple value connotations. The study concludes that healthy streets constitute an urban renewal method integrating environmental quality, social vitality, economic sustainability, and the quality of public life, enabling streets to become the health infrastructure for all.
