This article examines urban systems through the analytical framework of street-level urban metabolism, expanding upon Kennedy's multi-layered studies of urban metabolic processes. While traditional urban metabolism analyzes cities as macro-scale systems, this study focuses on neighborhood street networks as critical units of resource flow, applying Kennedy's indicator framework to a finer-grained assessment of streets as metabolic conduits. Focusing on Amman, Jordan, the study dissects seven key metabolic flows (e.g., water, energy, waste) at the street level, adapting methodologies from Rotterdam's neighborhood-scale metabolic analysis. This approach reveals how hyper-localized flows interact with environmental stressors such as water scarcity, extreme heat, and limited green infrastructure. By comparing four distinct typical neighborhoods in the city, the study identifies disparities in flow efficiency tied to urban design, offering targeted strategies to enhance resilience. The research's goal is to generate actionable strategies for enhancing urban infrastructure by mapping resource flows and proposing interventions. Ultimately, aiming to develop a scoring system that quantifies the impact of each flow within cities studied, and complemented by a survey to understand the local's perspective to identify analytically, flows and elements that enhance the city's metabolism and environmental stresses.
本文通过街道层面城市新陈代谢的分析框架来审视城市系统，扩展了肯尼迪对城市新陈代谢过程的多层次研究。虽然传统的城市新陈代谢将城市作为宏观尺度的系统进行分析，但本研究将社区街道网络视为资源流动的关键单元，将肯尼迪的指标框架应用于对作为新陈代谢管道的街道进行更细致的评估。该研究以约旦安曼为重点，在街道层面剖析了七种关键的新陈代谢流（如水、能源、废物等），采用了鹿特丹社区尺度新陈代谢分析的方法。这种方法揭示了超本地化的流如何与水资源短缺、极端高温和有限的绿色基础设施等环境压力源相互作用。通过比较该市四个不同的典型社区，该研究确定了与城市设计相关的流效率差异，提供了增强复原力的针对性策略。该研究的目标是通过绘制资源流并提出干预措施，生成增强城市基础设施的可操作策略。最终，旨在开发一个评分系统，量化所研究城市中每种流的影响，并辅以一项调查，以了解当地人的观点，从而分析确定增强城市新陈代谢和环境压力的流和要素。
