摘要：非典型性历史街区指街区内拥有一定数量的历史建筑，但街区传统风貌完整性与历史保护价值遭遇较大损坏，难以纳入到法定保护体系的传统街区。它的更新，承载着历史积淀和风貌特色，对提升城市品质、塑造城市特色具有重要意义。本文对非典型性历史街区的更新困境进行梳理，基于城市双修的视角，探索非典型性历史街区在保护、更新、发展三个维度中的对策。最后以浙江省杭州市桐庐县开元街的更新实践为例，总结归纳了其价值特色及面临问题；并针对性地提出了以需求为导向的功能修补、以提升为抓手的空间设计、以社区营造为手段的三大更新对策。由点及面，推进街区更新。发挥其在城市功能重塑、空间重构、文脉延续等方面的重要作用。

YU Yijie， CHEN Cheng， YIN Long

[Abstract] Atypical historical neighborhoods refer to the traditional neighborhoods that have a certain number of historical buildings in the neighborhood， but the integrity of the traditional features and historical protection value of the neighborhood have suffered great damages so that cannot be included in the legal protection system. Its renewal carries historical accumulation and features， which is of great significance for improving the quality of the city and shaping its characteristics. This article sorts out the renewal predicament of atypical historical streets， and explores countermeasures in the three dimensions of protection， renewal， and development based on the perspective of urban double repair. Finally， taking the renewal practice of Kaiyuan Street in Tonglu County as an example， it summarizes its value characteristics and problems； and proposes three major update countermeasures， which are demand-oriented functional repairs， space design with promotion as the starting point， and community building， in order to promote block renewal from point to plane and help with playing its important role in urban function remodeling， spatial reconstruction， context extension， etc.

引言

随着我国迈入城市化中后期阶段，城市发展亦逐步从快速扩张阶段向高质量发展阶段转型。城市稳步推进结构性调整，城市更新、城市双修等逐步成为城市发展的新路径。日益注重文化的延续与保护，追求整体品质的营造提升。在此背景下，一些處于老城区块的非典型性历史街区由于其独特的历史风貌和地段价值，逐步成为城市更新的热点。

这些街区，具有一定的历史文化保护价值，但面临较为严重的风貌缺失与功能衰退，难以被纳入到法定保护体系中。……
