Abstract：In the stage of improving the quality of the existing urban stock during China's urbanization process,the renewal design of old-city riverside greenways has become a crucial aspect of urban development.This paper focuses on the design of riverside greenways from the perspective of old-city renewal,analyzes the dilemmas in their renewal,such as spatial structural imbalance,lack of cultural gene decoding,and mismatches between functional supply and demand.Taking the Tonghui River Greenway in Meishan as an example,it examines the difficulties in its renewal,including spatial fragmentation,cultural disconnection,and functional mismatches.By introducing the theory of spatial justice,a trinity design strategy of'spatial patching-cultural decoding-functional coupling'is proposed.Through practical implementation,in terms of spatial patching,it is required to create a continuous and smooth walking experience,repair fragmented spaces,and achieve the integrity of the greenway system.At the cultural decoding level,cultural repair and cultural implantation strategies are adopted to reshape cultural memories.In the dimension of functional coupling,consumption scenarios are arranged in combination with regional cultures and the needs of citizens to realize the organic integration of functions and demands.This case provides replicable strategies for the organic renewal of old-city riverside areas in the era of existing stock,promotes the transformation of'functional greenways' into'warm urban life belts',enriches the theoretical research on the design of riverside greenways in urban renewal,and offers practical references for other regions.Meanwhile,it provides new ideas for the research on the organic renewal of old-city riverside greenways,thus having important theoretical and practical significance.
