Carbon cycle in the context of urban micro-regeneration: an analysis based on urban pocket parks

Abstract

Low-carbon urban development is a crucial link in reducing greenhouse gas emissions and achieving the "dual carbon" goals of carbon peaking and carbon neutrality. Most existing studies focus on either carbon emission reduction or carbon sequestration at the macro scale, and fail to systematically analyze the full urban carbon cycle process and its comprehensive benefits from a micro-spatial perspective. Taking urban micro-regeneration as an entry point, this paper adopts literature research and case analysis methods. Based on the binary logic of carbon sources and carbon sinks within the carbon cycle and the "Triple Bottom Line" principle, a "Dual Pathways—Three Dimensions" analytical framework is constructed. Using the micro-regeneration project of Rihui Green Space in Xuhui District, Shanghai, as a case study, this paper analyzes its underlying action mechanisms and conducts a comprehensive benefit evaluation. The study finds that carbon-cycle-oriented urban micro-regeneration can effectively reduce carbon emissions and enhance carbon absorption and fixation throughout the entire life cycle, contributing to environmental protection, economic development, and social equity, thereby promoting sustainable urban development. The analytical framework proposed in this paper can provide a reference for the low-carbon design and benefit evaluation of pocket parks.
