Starting from the study of the existing problems in the community building of traditional characteristic blocks,this paper finds that the introduction of external business activities improves the block environment and activates block life,but inevitably brings about conflicts between business and residence.Based on relevant research literature and practical case analysis,as well as the pilot work of community planning in the Hubu Alley traditional characteristic block in Wuhan,the paper puts forward the planning idea of "seeking integration based on separation"–adopting an environmental regulation strategy with "spatial separation" at its core and a community governance strategy with the "benefit sharing" at its core,to achieve the integration of business activities that are introduced from outside into the traditional characteristic block.
