Before 2003: Bahe River was also turned into a huge sand-dredging site. Villagers exploited the top quality sand for building throughout the area resulting in severe riverbed sinkage. Vast amounts of construction waste were also dumped along the river bank, amounting to nearly 500 million cubic meters.

Two decades of work have restored the ecosystem housing this expo. nue
- Xi'an authorities invested 1.3 billion euros in 2003 to restore Chanba's seriously damaged ecosystem. -25 drainage outlets along Chanhe River were blocked and sewage has been channeled into newly built treatment plants. - A number of polluting enterprises built along the river have been shut down or suspended. - Authorities directed river water into sand-dredging pits, which have gradually formed into natural wetlands. - 533 hectares of trees and grassland were planted along the river to help contain the water.

4000 sqm greenhouse
“The Greenhouse has a crystal-like, glass enclosure folded into a hillside. Inside, a horseshoe plan takes viewers through three climate zones encircling an outdoor courtyard.�
Circulation Routes Two paths bisecting the courtyard lead up over the greenhouse roof, turning indoor circulation into outdoor walkways and further mingling building and landscape. Rare Plant Planting Zone

The Eco-Plane explores how a minimal architectural feature can be utilized as an index of the delicate changes in topography and complex issues of interaction between the lake, plant life, and visitors to the park.
ECO-PLANE
Garden exhibit by Columbia University Students
- The Eco-Plane focuses on the edge condition between water and land. - Exaggerates the ecological tension at this edge condition to provide a territory that supports and encourages maximum biodiversity. - Monitors and reveals the effects of subtle fluctuations in the water level and provides an always-changing experience for visitors.

“The Garden of 10,000 Bridges represents the human life; the path of people’s lifetime, which is a route of uncertainty and burden, but also of highlights and elation. The garden design takes you on this walk of life as a meandering, winding trail – continuous and like a labyrinth. It lets you find your way through nature and takes you over 10,000 bridges.”
GARDEN OF 10,000 BRIDGES
Garden exhibit by Dutch Firm West 8
Plan of Exhibit
The firm decided to explore what it would be like if people decided to dig a giant tunnel that leads all the way to China. To evoke visions of distant lands and places the team added light audio of “cows from the pampas of the Argentinas, commuters rushing among transit through New York City, the maritime life of Stockholm, and layers of history so audible among the streets of Berlin.�

Section through Exhibit
Plan of Exhibit
The Garden is designed under the theme ‘the harmonious co-existence of nature and the city’. The garden is composed mainly of only four elements: traditional grey brick walls and paving, willow trees, mirrors, and bronze bells. “Each of these enhance the sense of discovery and anxiety, as if being lost in a city and forest simultaneously.”
THE MAZE GARDEN
Garden exhibit by Martha Schwartz Partners
Plan of Exhibit
The Botanist Garden is only a circular structure with a small garden core. It is designed to exhibit rare species of Chinese Plants. The thick ceramic enclosure creates a thermal insulation and thus a cooler, more humid environment apparently suitable for the species which inhabit it.
