第十屆江蘇省園藝博覽會博覽園主展館，揚州，中國

第十屆江蘇省園博會于2018年9月在揚州儀征舉辦。園區選址于棗林灣生態園，場地地勢平坦、依山傍水，東側為2021年世園會建設片區預留地。主展館坐落于博覽園入口展示區，是園區內最主要的地標建筑和展覽建筑，并在世園會期間作為中國館使用。

主展館汲取揚州當地山水建筑和園林特色的文化意象，從清代袁耀《揚州東園圖》中獲得啟發，以“別開林壑”之勢表現揚州園林大開大合的格局之美————南入口以高聳的鳳凰閣展廳開門見山，與科技展廳相連的橋屋下設溪流疊石，并延續至北側匯成水面，形成內外山水相貫之景。

設計順應地形，建筑體量總體由東南高點逐漸向西北方向降落，形成了徐徐下降的地平線，水庭也隨之跌落，并通過不同尺度的院落來分解體量，形成了隨水面依次展開的展廳序列，達到了園博建筑所追求的自然得體。展廳與林壑交織的回游式路徑使得建筑與景觀、室內與室外充分融合。

主要展廳采用現代木結構技術，最大程度簡化裝修，展現結構的自然之美。主要木構件均由工廠加工生產、現場裝配建造，不僅是一種綠色建造，符合節能環保要求，而且還有效提升了施工效率，解決了工期緊張的問題，對綠色設計和可持續發展起到積極示范作用。由于展館在博覽會后將被改造為精品酒店，所以設計兼顧了后續利用的合理性?！?/p>

2 外景/Exterior view

The 10th Jiangsu Horticultural Exposition was held in Yizheng, Yangzhou in September 2018. The Expo park is located in Zaolinwan Ecological Park,and the site is flat and near the mountain and by the river, with the reserved area for the 2021 World Horticultural Exposition's construction on the east side. As the main landmark building, the main exhibition pavilion is located in the entrance area of the Expo Garden.

Drawing on the cultural images of the local landscape architecture and gardens in Yangzhou,and inspired by Yuan Yao's painting "East Garden of Yangzhou" of the Qing Dynasty, the main exhibition pavilion expresses the beauty of the large opening and closing pattern of Yangzhou gardens with the image of "sudden view of forest ridges". The south entrance opens with the towering Phoenix Pavilion exhibition hall, and the stream under the bridge roof connecting with the science and technology exhibition hall runs down to the north and forms the water surface inside and outside, creating a coherent scene of landscape.

Conforming to the terrain, the overall building volume gradually descends from the southeast high point to the northwest, forming a slowly descending horizon, with the water courtyard landing on the lower end. The design uses courtyards of different scales to decompose the building volume, forming a sequence of exhibition halls that unfold with the water, achieving the proper nature characteristic of the horticultural Expo buildings. The interlaced corridor between the exhibition hall and the forest and hinterland makes the building and landscape fully integrated with the interior and exterior.

The main exhibition halls adopt modern wooden structure technology. The main components are manufactured by factories and assembled on site.It is not only a green construction, which meets the requirements of energy saving and environmental protection, but also effectively improves the construction efficiency, solves the problem of tight construction period and plays a positive role in the demonstration of green design as well as sustainable development. As the pavilion will be transformed into a boutique hotel after the Expo, the design also takes into account the rationality of the subsequent use.□

評論

張應鵬：作為整個博覽會最重要的建筑，主展館通過恰當升起的高度、水平延展的體量以及開敞靈活的平面布置，以3種不同的空間策略，實現了城市空間、園區空間以及建筑內部空間在3種不同尺度下的空間轉換。

“鳳凰閣”是主展館的最高部分，也是整個園區的最高點，在園區外很遠的地方就能看到?！傍P凰閣”以高起的形式承擔著園區在城市空間中應有的標識性功能。

但“鳳凰閣”僅僅是主展館在入口處局部高起的部分。主展館的主體部分則以低矮平緩為主，加之在縱深方向上隨地形高差由南向北漸次跌落，化整為零的院落空間很好地平衡了園區內部不同規模與不同類型的建筑在形式風格與空間尺度上的差異。

建筑內部，新型的現代木結構受力體系保證了相對完整的標準空間。既能滿足展會期間不同的陳列方式，又為今后使用功能的靈活轉換提供了空間與技術上的保障。

現代木結構的主要材料是膠合木，主要節點是鋼節點，保留了木材各種優越的天然屬性，同時改善了天然木材原有的受力缺陷。與傳統木結構相比，現代木結構受力更加合理，結構邏輯與空間邏輯更加清晰，這也最終直接形成了主展館特定的形式語言與空間特色，并同時實現了傳統木結構在技術與文化上的雙重轉譯。

Comments

ZHANG Yingpeng: As the most important building of the entire Expo, the Main Exhibition Hall has achieved a spatial transformation in different scales of urban space, park and building interior through strategies of proper rising height, horizontally extending volume and flexible plan layout.

"Phoenix Pavilion" is the highest part of the main exhibition hall and the whole park as well, so it can be seen from far away before entering the park. As an elevated construction, the Pavilion stands out as a symbolic image of the park in the city.

Notably, the "Phoenix Pavilion" is only partially elevated at the entrance of the Main Exhibition Hall,whose body is subject to a low and flat style. Besides,there are gradual falls from south to north along with the terrain elevation difference in the depth direction,and the courtyard space is broken into parts, conveying a balance in varying forms, styles and spatial scales of different buildings in the park.

Inside the building, the new load-bearing system of modern wooden structure ensures a relatively complete and standard space. It can not only meet the demands of different display needs during the exhibition, but also provide space and technical guarantee for the flexible conversion of functions in the future.

The modern wood structure, featured by steel joints, adopts plywood as its main material.Therefore, the superior natural properties of wood are all retained, and the original force-bearing defects of natural wood are improved. Compared to the traditional mode, the modern wooden structure has better force distribution, with clearer structural and spatial logic. In the end, it directly leads to the specific formal language and spatial characteristics of the Main Exhibition Hall, while achieving the double translation of traditional wooden structure in both technology and culture.
