INTERACTION Landscape architecture is my tool to understand the world. It is also a bridge for integrating Human society and Nature ultimately. I did five projects to explore the interaction of different fields between Human Society and Nature.

1 BRING PARK SKY VIEW Individual work July 2019 Instructor: Shunyao Hu Location: Chicago, United States Size: 0.63ha

Make use of the site sky view

Chicago, located in Illinois, USA, is a typical, highly urbanized modern city. The average height of the buildings is 130 meters. People can rarely see the sky landscape. I found that a beautiful sky view was reflected in the building's facade. The building was on the east side of the site. I planed to use terrain and plants to block the disturbance of surrounding buildings. Thus people could enjoy the large image of the sky above the green land.

Waste

2 WASTE REUSE & LAGOON AGRICULTURE Individual work December 2021 Instructor: Alex Wall

Location: Saugus, MA, United States Sea level rise

Waste is always assumed as useless and polluted, and sea-level rise is labelled as another troublesome issue. However, if we create new links between the two negative things, can we make something positive? Sealevel rise shapes a new type of land, named lagoon. It is a land covered by a thin layer of water. Lagoon losing its original function requires a new chance for reproduction and revival. If more waste is recycled, new material, such as compost soil and building material, can be produced and be helpful in the lagoon transformation. My two sites can show as an example of this connection.

3 INTEGRATIVE FOOD SYSTEM IN URBAN -Floating Food Island Group work December 2020 Instructor: Fang Wei, Jing Zhao Location: Shanghai City, China Site Size: 16.24ha

Integrate food networks on the viaduct systems

Much food waste is caused by the separation of rural and city, including transportation energy consumption, packaging consumables, low waste recycling rate, etc. Thus, building a food system in a city became a logical need. Besides, the expansion of transportation space in modern cities had caused unnecessary waste of land resources. Combining the two problems, I superimposed food networks on the viaduct systems. In Traffic roundabout, I designed to build threedimensional farms.

4 MINE RECOVERTY Group work September 2019 Location: Zhangzhou City, China Size: 520ha

Mining hurt the mountain

Illegal mining activities lead to deforestation in Zhangzhou mountain areas. In 2019, the forest enclosed by the mining area was completely disconnected from the surrounding forest. As a result, the ecosystem cannot exchange energy, and the birds' migration route is blocked. The average rainfall in Zhangzhou city is1000-1900 mm. A lot of rain fell on the bare land, which caused soil erosion. Town reservoirs and natural pools have become muddy "milk" lakes.

STRATEGY 1_ SOIL EROSION PREVENTMENT Profile construction strategy

Different levels of soil erosion Considering about the gradients of bare land and the flow of river, we divided the erosion river into six types. Then we proposed six possible plans perspectively. The plans included soil construction and planting methods.

5 RECONSTRUCTION OF GRAND CANAL WHARF Individual work Graduation project June 2020 Instructor: Fang Wei Location: Wuxi City, Jiangsu Province, China Size: 46.56ha

1992-2009 Cargo Wharf

2020 Water Pollution

The Grand Canal was listed as a world cultural heritage in 2009. The site is located in the Wuxi section of the Grand Canal and has a rich history. If parchment is repeatedly written and erased, the writing marks will remain on it each time. Like parchment, the design site also contains more than one layer of history. I selected two typical pieces of history. Then combine with the ecological problems of contemporary canal water pollution. The design is a superposition of three levels.

ANALYSIS OF THE CONSTRUCTION ALONG THE GRAND CANAL WUXI SECTION

CONCEPT

Analyze the overall cultural construction of the Grand Canal in Wuxi. In the reconstruction activities of historical sites, there are four types of built sites, including park green space, exhibition hall, remained historical site and port area.

I take this site as a piece of parchment, every construction and demolition in history will leave marks it. In the design, I integrate two historical levels, water village agriculture and industrial wharf, with the contemporary water ecology need.

The Grand Canal promotes the prosperity of Wuxi Rice economy. Rice is planted in the farmland along the river.

The shipping function of The Grand Canal directly promoted the prosperity and development of Wuxi City.

Along the canal is full of grain processing industry, textile industry, silk reeling industry.

The new canal is excavated to undertake the function of canal navigation.

Highway construction, large proportion of Wuxi passenger liner suspended.

Freight yard wharf was built in 1992. But the The canal freight volume reduced rapidly, the wharf was abandoned in 2009.

The government plans to build a green City Riverside Park.

MORPHOGENESIS

The sewage from the surrounding factories is discharged into the canal through the ship channel.

The original sewage is introduced into the site and purified step by step in the site.

Turn the original three rivers into one.

WATER PURIFICATION STRATEGY Subsurface flow wetland

Terrace aeration tank

Water flows step by step to reduce the precipitation of harmful substances. Filters between each stage can filter large particles of sand or garbage.

Adsorption of harmful substances in sewage with sandstone, activated carbon and diatoms. Add chemical precipitant to precipitate pollutants.

Terrace wetland

The use of surface plants for organic pollution purification can reduce the eutrophication of the canal water body. The water is stripshaped and can introduce human activities.

Central Lake

The open central lake provides a good view.

Floating wetland reservoir

The flow slows down in the reservoir and settles some organic particles from the pond.

Wetland

Water flows through the underground sand and gravel and adsorbed substances, which can reduce the site's soil hardening while eliminating pollution more efficiently.

BIRD'S EYE VIEW Keep the original factory building and transform it into a sightseeing pavilion.

Keep the original container and transform it into houses in the silk processing experience area.

Imitate the agricultural texture of the water village and grow rice.

Keep the original remains of the tower crane. Build a two-story veranda on the basis of it.

The wetland has a water purification function. It also serves as a resilient area for floods.

URBAN AGRICULTURE

Change the rails, the wharf remains, into planting ponds.

The field of vision is wide, a n d I c o m e h er e ever y week to take pictures.

I take my family here for a walk after dinner every day.

Thanks for the construction of the park for providing me with a job.

The ecological environment here is amazing! There are many cute wild animals!

The wheat sprouts that I claimed here on the railroad tracks have grown again last week, and it is really nice to take care of them.

Here is the perspective of the Urban agriculture area. The abandoned railroad tracks are used as small rain gardens along the bridge. The vision is wide and pure, and the animals and plants grow naturally. 55


SILK CRAFTS EXHIBITION HALL Convert containers, the wharf remains into buildings.

The silk here is really a work of art.It ’s so fun to experience the Chinese traditional sericulture culture.

The bamboo buildings there are so interesting, I come to see the new silk every weekend!

The lit tle flowers here are ver y beautiful! I can also experience the making of silk myself!

Here is the perspective of the Silk crafts exhibition area. The original steel frame on the site will be used to dry silk. Tourists can participate in every process of sericulture. 56
