Research on Landscape Renewal Design Strategies for Historic Districts Based on the CGC Model

Abstract

Abstract— In the stock era, urban renewal, especially the renewal of historical blocks, is facing great challenges: local cultural genes are being lost, while design forms are experiencing repeated homogenization. In order to solve the current design contradictions, it is necessary to study and build a CGC (collage-gene coupling) update model to avoid relying on linear design derivation by bridging the theoretical gap between the cultural genetic theory and the collage urban framework. Use the NVivo qualitative analysis method to encode the original data and analyze relevant cases to transform implicit design intuition into practical strategies. This workflow covers all aspects from deep gene identification to precise spatial operation. A comparative empirical study of the Castelvecchio Museum and Guangzhou Yongqing Fang has verified that effective urban collage is not the arbitrary accumulation of formal fragments, but the syntactic reconstruction of the deep genes of the site. The establishment of the CGC theoretical model provides a rigorous guidance for the field of urban renewal, so that it can maintain adaptability in different cultural contexts.
