上海乐山绿地口袋公园 / VIA维亚景观

全龄化与多功能集成：重塑城市公共生活核心：该项目成功将一个功能衰退的老旧绿地，转变为一个服务于全龄段人群的、高品质的城市公共空间。设计以“众乐之源”为核心理念，巧妙整合了适老、适幼的游憩设施、社区共享阅读空间、管理用房，并通过定制化的健身器材和儿童游乐区，实现了景观、休憩、活动、服务的多元功能复合。这种一体化的解决方案，不仅响应了当代市民对高品质户外活动的需求，更提升了口袋公园作为城市“景观公共物品”的价值，有效重构了周边高密度社区的公共生活体验。

空间序列的精妙构建与场所精神的塑造：项目以全长80米的“众乐之廊”作为核心结构线索，极具匠心地划分了内外空间层次。廊外设计面向街道，采用平缓折叠的暖色树池，优化了步行体验并融入街道肌理；廊内则聚焦于内部的自然、明快氛围，以“乐之源”社区舞台为中心组织活动。通过轻型结构确立了场所精神（Genius Loci）的载体，同时约400米的环形慢跑道将廊内外的不同体验有机串联。这种内外有别、层次丰富的空间序列，极大地丰富了口袋公园的使用体验，体现了对传统造园智慧的当代转化。

传统文化语境下的当代设计转化：设计思维深刻，引用了王世贞“山以水袭”的古典园林意境，提出了“山以水型·山水相袭”的空间构型逻辑。这使得设计能够在满足当代人行为需求的同时，巧妙地植入“聚散、动静、旷奥”等传统山水哲思。此外，项目将建成环境视为可阅读、可互动的“空间文本”，通过设计可坐、可玩、可发光的互动构件，激发市民基于个体经验的“生活艺术”，体现了建筑师对公共空间如何促进社会互动和文化延续的深刻思考。

The renovation design of Leshan Green Space, initiated in the 1980s and covering approximately 5600㎡, is situated in the central area of the Leshan Community in Xuhui District, serving as the sole concentrated public open space for the surrounding area. Prior to the renovation, the green space suffered from dim interiors, outdated facilities, and functions that failed to meet contemporary citizens' recreational needs. Simultaneously, the area is embraced by residential communities and is adjacent to office parks, Shanghai Jiao Tong University, primary schools, and kindergartens, all within 800 meters of Xujiahui.
乐山绿地，始建于上世纪80年代，占地约5600㎡，地处徐汇区乐山社区的中心区域，是周边地区唯一的集中公共开放空间。改造前绿地内部空间阴暗、设施陈旧、功能与当代市民游憩需求无法匹配。同时，绿地不仅为居住社区环抱，也紧邻办公园区、上海交通大学、小学幼儿园等文教办公设施，距徐家汇不过800米。

The update of Leshan Green Space takes "joy" (乐) as its foundation, organizing a diverse landscape space based on the concept of "Source of Collective Joy" (众乐之源) that accommodates the elderly and children, is suitable for viewing and recreation, allows for rest and play, and facilitates reading and sharing. The design, tailored for all ages and times, provides an integrated solution for landscape public goods for the entire community. It also presents the surrounding residents and office workers with a fashionable and beautiful urban fifth facade, reconstructing the excitement of public life behind the bustling Xujiahui urban area, and positioning the pocket park renovation as a crucial catalyst for reactivating urban public life.
乐山绿地的更新设计以“乐”为基点，以“众乐之源”的立意组织适老适幼、宜游宜观、可憩可玩、可阅读能共享的多元景观空间，以全龄段全时空可游憩的设计为整个社区提供了景观公共物品的一体化解决方案，同时也为周边居民与办公人群呈现了时尚优美的城市第五立面，重构徐家汇城市繁华背面公共生活的精彩。也让口袋公园的更新改造成为再次激活城市公共生活的重要触媒。

The design of Leshan Green Space centers around the 80-meter-long "Corridor of Collective Joy" (众乐之廊) as the main spatial clue. The large-span lightweight structure ensures unimpeded sightlines and behavior both inside and outside the corridor, also serving as the carrier for the "Genius Loci" subtly hidden within the greenery. The space under the "Corridor of Collective Joy" integrates landscaping to provide citizens with interesting shaded and rain-sheltered leisure areas. It also incorporates functional spaces such as indoor shared reading rooms and green space management offices, responding to numerous public issues like public space recreation, community governance, and public management. On the exterior, the design sets back 20 meters along Leshan Road, shaping the green space environment on this side into an outward-facing landscape that fully integrates with the street, optimizing the pedestrian walkway environment of Leshan Road. Gently folding warm-colored tree pits simulate "flat small hills," merging "joy" (乐) into "mountain" (山). The interior side of the "Corridor of Collective Joy" strives to create a natural, bright, and stable atmosphere, centered around the "Source of Joy" community stage integrated with a musical dry fountain, with other green space functional areas arranged concentrically around it. Fully customized shared fitness facilities and children's fun spaces are merged into the surrounding landscape, and outdoor seating areas are arranged based on solar analysis results.
乐山绿地的设计以全长80米的“众乐之廊”为主要空间线索，大跨度轻型结构保证了廊内外视线与行为的通畅，也成为隐现于绿色中的“场所精神（Genius Loci）”的载体。“众乐之廊”不仅在廊下空间结合造景为市民提供了遮阳避雨的趣味休闲空间，也整合了室内共享阅读空间、绿地管理用房等功能，响应了公共空间游憩、社区治理、公共管理等诸多公共议题。“众乐之廊”外侧在设计中沿乐山路退让20米，将这一侧绿地环境塑造为完全融入街道的外向型绿化景观，优化乐山路人行道步行环境，更以平缓折叠的暖色树池模拟“平坂小冈”，融“乐”于“山”。“众乐之廊”内侧则追求自然、明快、稳定的环境气氛营造，以结合音乐旱喷的“乐之源”社区舞台为中心，环绕布置其他绿地功能空间。将全设计定制的共享健身设施、儿童趣乐空间融于周边的绿化景观中，根据日照分析结果布局室外休闲座椅。

Furthermore, a circular jogging track, approximately 400 meters long, organically connects the spaces outside, underneath, and inside the corridor. The corridor is not only the most significant structural representation of Chinese garden history but, in Leshan Green Space, the "Corridor of Collective Joy" is a crucial element in enriching the layered experience of the pocket park, presenting diverse public integration, and shaping the Genius Loci.
又以全长约400米的环形慢跑道，将廊外、廊下、廊内有机的组织在一起。游廊不仅是中国造园史中最重要的结构性园景表征，在乐山绿地，“众乐之廊”更是丰富口袋公园体验层次、呈现多元融合的公共性和塑造场所精神的重要内容。

Currently, urban landscape renewal in Shanghai has entered a new phase of "integrated regional governance and renewal." While maximizing the retention of existing mature trees, Leshan Green Space proposed a creative approach for overall structural optimization in its design. The design is based on a concise and bright structure that meets contemporary behavioral and experiential needs, while also drawing inspiration from classics. Wang Shizhen wrote in "Records of Yanshan Garden" that "mountains following water is extremely marvelous; mountains gaining water is even more marvelous." The design for Leshan Green Space thus proposes the spatial configuration logic of "mountains shaped by water, succession of landscape" (山以水型·山水相袭), presenting the connotations of traditional Chinese garden culture based on landscape patterns—such as convergence/dispersion, dynamic/static, winding/straight, and expansive/secluded—through contemporary design language. This appropriately responds to the preferences of Leshan community residents for themes like "landscape" (山水) and "joy" (乐).
目前，上海的城市景观更新已经进入“片区一体化治理更新”的全新局面，在尽可能保留现状乔木的基础上，乐山绿地在设计中提出了整体结构优化的创作思路。设计以符合当代行为和体验需求的简洁明快的结构为基础，也在经典中挖掘灵感。王世贞在《弇山园记》中写道“山以水袭，大奇也；山得水，复大奇”，乐山绿地的设计进而提出“山以水型·山水相袭”空间构型逻辑，将中国传统园林文化中基于山水格局的“聚散、动静、曲直、高下，旷奥”等内涵以当代的设计语言呈现出来，同时也恰当的响应了乐山社区居民对“山水”、“乐”等主题的偏好。

While emphasizing overall spatial structure and logic, the renovation design of Leshan Green Space regards the landscape space as a carrier for stimulating positive citizen activities and promoting public life. Through the creation of green landscapes and spaces, the built environment becomes an object that can be read and interacted with. The design integrates seating that can be sat upon and played with—white artistic concrete benches—with the green landscape to inspire unrestricted, enjoyable activities; it provides surprises for children's fun areas through gravity-sensing luminous benches; it offers a richer, delayed experience for the central musical dry fountain through a 5mm sunken site design, allowing the water mirror after the fountain show to become the children's next "natural toy"; and it allows every user to find their own corner through the excavation of traditional concepts like "moving scenery reveals new views" (步移景异). If the continuously evolving urban context of Shanghai is a thick book, the renewal of Leshan Green Space might be one page in this "spatial text," requiring users ("readers") to read, dialogue, and evaluate based on their individual experiences. The "Living Art" composed of the wonderful usage by every user will be the true protagonist of urban renewal and public life.
乐山绿地的更新设计在注重整体空间结构与逻辑的同时，将景观空间视作激发市民良性活动、促进公共生活的载体，通过绿化景观与空间营造使建成环境成为可阅读、可互动的对象。设计通过可坐、可玩的白色艺术混凝土坐凳与绿化景观融合，激发非限制性趣味活动；通过可发光的重力感应坐凳，为儿童趣乐空间提供惊喜；通过下凹5mm的场地设计，为中心音乐旱喷提供更丰富的延时体验，让喷泉落幕后的水镜成为孩子们的下一个“自然玩具”；通过传统挖掘的步移景异，让每个使用者都能找到属于自己的角落。若持续演进的上海城市文脉是一本书，那乐山绿地的更新或许是厚厚“空间文本”中的一页，需要使用者（“读者”）基于自己的个体经验去阅读、对话、评价，每个使用者的精彩使用所构成的“生活艺术（Living Art）”将是城市更新与公共生活的真正主角。

Pocket parks generally refer to public green spaces covering an area between 1,000 and 10,000 square meters. Although their scale does not meet the standard of traditional parks, pocket parks are particularly important for their social functions, ecological attributes, and aesthetic presentation in high-density urban spaces. Leshan Green Space in Shanghai's Xujiahui area is a significant representative. The renewal of Leshan Green Space specifically focused on the design of the "mouth" (口), emphasizing an open posture towards the block to optimize behavioral permeability and integration with the streetscape, making the renewed green space the most crucial link in the overall slow-traffic system of the block. Meanwhile, based on the conclusions of user need surveys conducted with community residents, diverse and characteristic functions were effectively organized, integrating activity spaces with natural green landscapes so that every "pocket" (袋袋) can accommodate appropriate levels of fun, fitness, and leisure activities in a stable and safe environment.
目前，口袋公园多指占地面积在1000至10000平米之间的公共绿地，其规模虽达不到传统公园的标准，但在城市高密度空间，口袋公园的社会功能、生态属性、风貌呈现则尤为重要，位于上海徐家汇地区的乐山绿地就是其中的重要代表。乐山绿地的更新特别关注“口”部设计，强调面向街区开放的姿态，优化沿街的行为渗透融合，让更新后的乐山绿地成为整体街区慢行系统中最重要的一环。同时，基于社区居民使用需求调研的结论有效组织多元特色功能，将活动空间与自然绿化景观融合，让每个“袋袋”都能在稳定安全的环境下承载恰当的趣味、康体、休闲活动。

Considering the scale limitations, Leshan Green Space inevitably faces a certain degree of spatial competition in usage. To ensure the "quasi-public goods" attribute of the pocket park, the design sought to increase the spatial capacity of the green space as much as possible by increasing landscape layering and strengthening the coupling between pathways and leisure areas, thus better presenting the characteristics of being all-age, all-time, and non-exclusive. Furthermore, through full public participation throughout the process, the renewed pocket park has become a truly inclusive open public center for the community. As a representative of emerging pocket parks in Shanghai, the renovated Leshan Green Space not only has optimized functions and a distinct image but also emphasizes a landscape feature based primarily on greenery, expressing seasonal changes through four seasons of plants, and maintaining low ecological maintenance. Moreover, balancing integration with the urban streetscape against the perfection of the "garden" system will likely be an important issue that every pocket park needs to carefully study during its creation process today.
考虑到规模限制，乐山绿地在使用上必然存在一定的空间竞争性，为了确保口袋公园的“准公共物品”属性，设计上通过增加绿地层次、强化路径与游憩空间的耦合，尽可能的提升绿地的空间容量，更好的呈现全龄、全时空、非排他的特征。同时，通过全过程的公众参与，使更新后的口袋公园成为真正具有归属感的社区开放公共中心。更新改造后的乐山绿地作为上海新兴的口袋公园代表，不仅功能优化、形象鲜明，也强调以绿为主、四时植物季相表达、生态低维护的基础园景特征。此外，如何平衡面向城市街道的融合与作为“园”的系统完善，或许将是当下每个口袋公园在营造过程中都需要仔细研究的重要议题。
