第十三屆中國（徐州）國際園林博覽會綜合館暨自然館，徐州，中國

徐州園博會綜合館暨自然館位于博覽園東側，東倚山體，西望各城市展園。建筑設計以宛若天開為意向，以徐州漢代的層臺瓊閣為形象，將場地地形與歷史意向緊密結合，形成補山、藏山、融山、望山之勢。

由于場地環境復雜，建筑需要充分彌補因開采而導致山體破壞的自然環境，并取得和自然的新平衡，從而為整個園博區域增色。設計通過與自然和諧共生的方式，使建筑充分呼應地形并體現地形之勢；在剖面上通過巧妙設置階梯式的空間，讓參觀者可以從外到內、從下至上不斷感受自然的延續。

設計借鑒徐州漢文化中層臺瓊閣的意象，以鋼木樓閣的方式設置主展廳，從而與基座空間形成對比，將光線和自然引入建筑內部，形成了天庭望山的效果。同時，設計借鑒漢文化中的苑囿意象，提出依據環境而設計的補山成房、修宕成臺的理念，以臺地景觀連接不同宕口和場地中的不同標高，順山而下，修補地形。建筑和景觀依山勢向西層層跌落，為人們提供了綜合館面向園博主展區的眺望視野?！?/p>

The Complex Pavilion and Nature Pavilion is located on the east side of the Expo Park, with the mountain to the east and the city exhibition parks to the west. Its architectural design, based on the image of Xuzhou high-platform pavilion in the Han Dynasty, successfully combined the topography and history of the area to make full use of its location,making it a harmonious building in the mountain area.

Given the complicated environment conditions of the site, the architecture should well restore the damages caused by mining to the mountain, and achieve a new balance with nature, thus becoming a striking part of the whole Expo Park. By staying true to the principle of harmonious coexistence with nature, the building fully responds to its terrain features in design. For example, the stepped section of the space will enable visitors to feel the continuity of nature from an all-round perspective.

By referring to the image of the high-platform pavilion in Xuzhou Han culture, the design created a main exhibition hall with steel and wood structure, showing a contrast with the base space.Natural light and scenery are introduced into the interior space, allowing visitors to overlook the mountain. Meanwhile, it also drew ideas from the Yuanyou (an enclosed ground for raising animals in ancient China) in Han culture, putting forward the environment-based design concept of building houses by restoring the mountain and platforms by renovating pits. In this way, different platform landscape will be connected on different elevations by different pits and sites, contributing to repairing the mountain terrain. The building and landscape together form descending layers towards the west along the mountain, providing people with a panoramic view in the Complex Pavilion to appreciate the Expo Park.□

評論

馮正功：徐州為華夏九州之一，是兩漢文化的發源地，山脈起伏，丘陵密布。徐州園博園綜合館項目，以其厚重、莊嚴、疊落的造型，回應了兩漢文化的建筑特征，“補山、藏山、融山、望山”策略的恰當運用，使建筑與自然融為一體。

中國傳統建筑圖樣中的“側樣”，類似于現代建筑設計中的“剖面”，“ 側樣”是傳統建筑建造活動中用于推敲建筑關系的重要一環。綜合館即通過精妙的剖面設計，為公眾提供了一個特別的空間體驗。錯層的通高展廳在引入陽光、風與自然山景的同時，其頂部鋼木結構的完整呈現及空間的錯動與滲透，使建筑空間兼具現代性和古典性，與西班牙當代建筑師巴埃薩作品中空間與光的應用有異曲同工之妙。

兩漢時期的層臺式建筑，多以高大的臺基承托上部木構主體建筑。綜合館取其意，以層臺的手法重構場地之肌理，以自然山勢烘托建筑之氣勢，木構、坡屋頂與山石的結合，成功再現了傳統建筑的地域特征。

庭院是中國建筑的另一個重要元素。綜合館通過前后庭院的植入，解決了建筑基座部分的采光通風問題，更通過空間的內外交融，回應了建筑與自然和諧共生的傳統理念。

從中國傳統建筑中汲取智慧，并用現代語言、現代材料、現代方法進行得體適宜的轉譯。綜合館的設計，為中國當代建筑的地域性表達提供了一種可借鑒的有效途徑。

Comments

FENG Zhenggong: As one of the nine prefectures in ancient China, Xuzhou is the birthplace of Han culture,with undulating mountains and dense hills. The Xuzhou Garden Expo Park Complex Pavilion project well demonstrates the architectural characteristics of Han culture with its thick, solemn, and overlapping shape. It appropriately applied the mountain-based strategy to integrate the building with nature.

The "Ceyang" in traditional Chinese architectural drawings, similar to the "section" in modern architectural design, makes sense for examining the relationship between buildings. With an exquisite cross-section design,the Complex Pavilion successfully provided the public with a special experience space, in which sunlight, wind and natural mountain views are introduced into the split-level,high-rise exhibition hall. The perfect presentation of the steel and wood structure on the top and the dislocation and penetration of the space make the architectural space both modern and classic. The application of space and light is reminiscent of the works of the contemporary Spanish architect Alberto Campo Baeza.

In the high-platform buildings of the Han Dynasty,the main timber structure building above is supported by a high platform. Taking this as an example, the Complex Pavilion re-construct the structure of the site with platforms, aiming at setting off the momentum of the building with natural mountains. The combination of timber structures, sloping roofs and mountains and rocks successfully represent the regional characteristics of traditional buildings once again.

The courtyard constitutes another significant element of Chinese architecture. The implantation of the front and rear courtyards not only gives solution to the ventilation problems of the base part of the building, but also integrates the internal and external spaces, responding to the traditional concept of harmonious coexistence between architecture and nature. The Complex Pavilion design, an example that draws insights from traditional Chinese architecture and transforms the traditional elements properly with modern design language and materials, has provided an effective reference for contemporary Chinese architectural design for a better regional expression.
