2024年成都世界园艺博览会主展馆 / 中国建筑西南设计研究院有限公司前方工作室设计三院

引言 Introduction

 

2024年成都世界园艺博览会主展馆坐落于成都东部新区，北临绛霞湖，南倚自然浅丘，西临园区内道路，东接世园东路。作为本届世园会的核心建筑，承担博览会期间的闭幕式、国际花卉竞赛展、会时论坛等重要活动功能。会后主展馆做局部功能调整，可持续作为成都东部新区文化活动中心使用。

 

The Main Pavilion of the International Horticultural Exhibition 2024 Chengdu is located in the Chengdu Eastern New Area, bordered by Jiangxia Lake to the north, natural hills to the south, inner park roads to the west, and Shiyuan East Road to the east. As the core building of the exposition, it is programmed to host significant events such as the closing ceremony, the international flower competition exhibition, and various forums. Following the event, the pavilion will undergo localized functional adjustments to serve as a civic cultural center for the Chengdu Eastern New Area.

With area of approximately 23,000 square meters, the project primarily encompasses a multi-functional performing hall accommodating 1,000 people, exhibition spaces, commercial areas, and office facilities. The Main Pavilion is not merely a functional venue for international gatherings; it represents a localized construction of the modern understanding of Sichuan’s natural and humanistic environments. The design respects the site’s natural context, adopting a scale and formal language that closely relates to nature, integrates historical and cultural elements, and actively manifests the social attributes of modern public architecture.

消解形体，建筑融入式嵌进自然 Dissolving Form: Architecture Embedding into Nature

 

主展馆项目用地位于两山之间的浅丘谷地，北侧绛霞湖湖面最窄处仅为85m，场地内最大高差达26m。在相对狭窄的山水环境中，建筑体量无疑是一个“巨构”，设计基于环境融合理念、尺度控制要求、滨水建筑亲水特点及对现状自然环境资源的理性分析，将约1.2万㎡的展厅、文化艺术活动、配套车库等功能滨水（绛霞湖为人工泻湖）设置于场地北侧的滨水处，节省土方填挖的同时形成北侧亲水界面，并以多级观景台阶看台过渡，形成多个不同标高的观景平台。在东侧结合地形形成“双首层”入口，为城市提供多场景使用的交通流线。消解的形体以更好的尺度嵌入原始地形中，看见建筑也见山水。

The project site is situated in a shallow hilly valley between two hills. To the north, the narrowest point of Jiangxia Lake is merely 85 meters wide, and the site features a maximum elevation difference of 26 meters. In such a landscape, the building’s volume could easily become an overwhelming “megastructure”. Based on the philosophy of environmental integration, requirements for scale control, the hydrophilic nature of waterfront architecture, and a rational analysis of existing natural resources, the design strategically embeds approximately 12,000㎡ of exhibition halls, cultural and artistic activity spaces, and supporting garages along the northern waterfront (Jiangxia Lake is an artificial lagoon). This approach minimizes earthwork while creating a northern hydrophilic interface, utilizing multi-tiered viewing steps and grandstands to form several observation platforms at different elevations. On the eastern side, a “double ground floor” entrance is integrated with the topography, providing a traffic circulation system suitable for multi-scenario urban use. The dissolved architectural form embeds itself into the original terrain with an appropriate scale, allowing observers to appreciate both the architecture and the natural landscape.

模糊边界，体验空间的流动性 Blurring Boundaries: Fluidity of Experiencing Space

 

设计的拓扑构成源自四川民居空间的流动性，以建筑本体为锚点，将空间流动的视觉体验聚焦于环境景观，使体验关注于空间形体与景观场景的交互过程，而非其中一方面。根据功能需求对空间进行开孔，形成多处室内外的贯通空间。流动性形体的屋面整合被分解的建筑体量，水平展开匍匐于环境之中。视觉体验在山水之间展开和游走。

 

▼剖面分析，Sectional analysis

 

 

The topological composition of the design originates from the spatial fluidity characteristic of traditional Sichuan residences. Using the architectural body as an anchor, it focuses the visual experience of flowing space onto the environmental landscape, thereby directing the experiential focus toward the interactive process between spatial form and landscape scenes, rather than isolating either aspect. Punctures are introduced into the space according to functional requirements, creating multiple penetrating areas that bridge the indoors and outdoors. A dynamically flowing roof integrates the decomposed building volumes, expanding horizontally within the environment. Consequently, the visual experience unfolds and wanders seamlessly among the mountains and waters.

书写人文，成都人文符号的在地性提炼 Humanities Writing : The Localized Extraction of Chengdu’s Cultural Symbols

 

与建筑的“地域性”强调某一地理区域共享的自然人文环境共性不同，建筑的“在地性”与建筑场地所处地方的特点特征、自然环境和人文环境有着紧密相关的特性，它强调的是一种与众不同的个性特征，即独特的融入环境的方式。设计从众多关联成都人文要素的关键词入手，选取三星堆“神鸟”及市树“银杏”为人文表达元素，进行空间形式书写。“神鸟”古拙曲线构成婉转灵动的屋顶姿态，体现“神鸟衔花”的意向；漫延室内外的“银杏天幕”以朴素的语言回应与自然的对话，在银杏树下，风动、叶动、心动，自然与人文的有机结合，给空间体验一个在地性唤醒。

 

▼在地性意向的汇集与提取，Collection and extraction of localized motifs

 

 

Unlike “regionalism,” which emphasizes the shared natural and cultural commonalities of a broader geographical area, “site-specificity” is intimately tied to the specific traits, natural setting, and humanistic context of the site itself. It highlights a distinct, individualized character—a unique way of integrating into the environment. Drawing from numerous keywords associated with Chengdu’s cultural elements, the design selects the Sanxingdui “Divine Bird” and the city tree, the “Ginkgo,” as elements for humanistic expression to dictate the spatial form. The primitive and unadorned curves of the “Divine Bird” shape the graceful and dynamic roof, embodying the motif of the “divine bird carrying flowers”. Meanwhile, the “Ginkgo Canopy” which spreads across both indoor and outdoor spaces, responds to the dialogue with nature through a modest architectural language. Beneath the “Ginkgo Canopy”, as the wind blows and the leaves flutter, the heart is moved; this organic fusion of nature and humanities provides a localized awakening to the spatial experience.

工于技巧，系统性解决工程难点的智慧实践 Mastering Techniques: Intelligent Practice Systematically Solving Engineering Difficulties

 

绿色建筑的核心内涵在于通过被动技术实现功能的需求与目标，而外延则是将承载功能目标的相关空间构件及设备系统赋予审美的形式。设计结合地形地貌、成都气候特点及建筑功能的使用场景工况需求，优先采用被动绿色节能技术，系统性采用适宜的主动技术手段，实现建筑本体（绿色）目标。被动式技术包含通过空间组织实现土方平衡，为自然通风及采光提供便利，同时考虑会后功能的低资源消耗平顺转换。

The core connotation of green building lies in achieving functional needs and goals through passive technologies, while its extension involves endowing the spatial components and equipment systems that carry these functional goals with aesthetic forms. By combining the topography, Chengdu’s climatic characteristics, and the operational requirements of the building’s functions, the design prioritizes passive green energy-saving technologies and systematically adopts appropriate active technical measures to realize the building’s intrinsic green objectives. Passive techniques include achieving earthwork balance through spatial organization, facilitating natural ventilation and daylighting, and considering a smooth, low-resource-consumption transition for post-expo functions.

The prevailing northern wind is cooled as it passes over the lake surface, entering the building through the basement corridor and the sunken courtyard, thereby enhancing the comfort of the interior spaces. The sunken courtyard introduces sunlight and rain into the lower levels, ensuring that 60% of the usable space receives more than 6 hours of natural light daily, with an average illuminance of 300lx.

Taking into account a comprehensive range of factors—including construction technology, cost, schedule, and regional cultural expression—the design carefully calibrates the scale, density, hierarchy, color, lighting, and tectonic methods of the “metal ginkgo leaves,” presenting a new humanistic landscape in a harmonious manner. Leveraging a profound understanding of material properties, aluminum panels are utilized to sculpt the diverse, complex curved surfaces of the roof. Active technologies include downsizing the HVAC system to provide flexible control for energy-efficient operation and maintenance, as well as utilizing electrically operated ventilation windows for airflow management to achieve natural ventilation. The plaza paving extensively employs permeable concrete, with richly formed grassy slopes and tree planters arranged three-dimensionally, providing resilience and comfort to the micro-environment while integrating the architecture with nature.
