摘 要：城市空间多样性的本质是社会结构多样性，而社会结构多样性反映了社会生态链多元稳定的特征，是不同人群社会需求的真实体现，反过来又赋予了城市空间多样性的社会价值。城市修补给予了城市规划和建设中原有的不足之处一次进行修改并完善的良机。基于“城市修补”的理念，规划应综合考虑以下几点：①加强对既有城市空间特征的深入调研和综合评估；②完善城市公共空间的总体规划布局；③注重传统城市空间“斑块”的保留和功能转型；④慎重对待原有城市支路网结构的保存和改造；⑤鼓励特定街区土地的兼容混合使用；⑥保障城市公共空间类型的多样化；⑦增强对建成区小尺度公共空间的场所营造；⑧提升公共空间的认知度；⑨在综合考虑交通影响的前提下打破封闭式围墙，活化街道空间；⑩在城市修补过程中引导当地居民参与社区的规划决策。

Abstract ：The essence of urban spatial diversity is the diversity of social structure, which reflects the characteristics of pluralistic stability of social ecological chain and different needs of different groups of society. It, in turn, gives the social value of urban spatial diversity. City betterment programs can help to improve the original urban planning and construction. Based on this concept, urban planning should be as follow: (1) strengthening in-depth research and comprehensive assessment for the existing urban spatial characteristics; (2) improving the overall layout of urban public space; (3) paying attention to the retention and functional transformation of traditional urban space; (4) carefully planning the preservation and transformation of the original urban branch network structure; (5) encouraging mixed use of land in some specific blocks; (6) protecting the urban public spatial diversity; (7) enhancing the construction of small-scale public space in the built area; (8) enhancing the cognitive of public space; (9) breaking closed walls and activating the street space based on comprehensive consideration of traffic; (10) guiding the residents to participate in community planning and decision-making in the process of urban repair.
