Proposed Activities

01. Healing Garden

Adjuvant therapy with vegetation Year: 2016, Individual work

The site is located next to a hospital in Tianjin, China, which is nearby a crowded crossing with few green areas for public. This project proposed a healing garden for the hospital, which provide more natural treatments for the patients. This design have positive impacts on patients in physiology and psychology through external stimulus from vision, smell, hearing, touch, etc. to strengthen the interaction between people and landscape consciously. The main users are patients from the hospital and groups from the nearby communities. Gardening activities are encouraged to enhance the self-esteem of patients and make them gain the sense of achievement while planting flowers.

Site Analysis Function The site is close to a hospital, a school, and a dwelling district, which has dense population but lacks public space.

Circulation Traffic is heavy in intersections, so the emergency channels are usually blocked.

Greenspace There are few greenbelts around the site, so the residents here cannot touch a large greenspace.

Planting Concept- A Therapeutic Garden

Master Plan Through analysis, using plants to set up different theme gardens, it is convenient for patients to produce different psychological feelings through interaction with plants. Meanwhile, set up sunken square and woodland area, to help patients insulate external noise and enjoy a quiet environment.

02. Tomb: City Of The Dead

Reorganization of life for marginalized population in the area of tomb Year: 2016, Individual work

The city of the dead in Cairo, Egypt is the cemetery of Egyptian nobilities.

Egyptians adopt the traditional ground burial, and their burial chamber is a house of courtyard style with a roof and a yard. Meanwhile, the nobilities hire the poor to live in their burial chambers for guarding. With the sharply increasing population in Cairo, there are not enough places to live, so more and more people come to this burial chamber, which form a mixed dwelling between the living and the dead. In order to improve the living conditions of the citizens. Roof and flank of the burial chamber will be reused to create new facilities. The main purpose of the project is creating separated spaces between living men and the dead to improve the public health. In the meantime, new planting space, marketing area and public spaces for communication are designed to create a self–sufficient community.

Site Analysis

Challenges

This site is located in a famous burial chamber in Cairo, Egypt, which is called the city of the dead. At present, it has become a famous slum where living men and the dead live together. The traditional cemetery has a courtyard, wall, gate, rooms and burial chamber.

Living in the burial chamber leads to problems of poor public health, less education and more serious crimes.

Analysis of Saline-Alkali Degree

03. Renascence Of Saline-Alkali Soil

The site belongs to the saline-alkali area in North China, and the densely distributed saline-alkali soil here has a serious impact on the growth of local crops.

Solving the problems of saline-alkali soil and local fluorosis Year: 2017, Individual work

The site is located in Haixing county, Hebei province. Fluorine ions in the surface water of this region is excessive, which results in serious endemic fluorosis as well as dental fluorosis and skeletal fluorosis of residents. Meanwhile, owing to the large area of saline-alkali soil, the crops cannot grow well and residents have a hard life. Through my research, Hydrilla Verticillata and Salicornia europaea L(also known as samphire) can solve the problem of both fluorosis and saline-alkali soil at the same time. For one thing, Hydrilla Verticillata can absorb fluorine ions to reduce the fluorosis ions content in water, and the Hydrilla Verticillata after absorbing fluorine ions can made into a pesticide to kill the injurious insect called inchworm that parasitizes Salicornia europaea L. For another, planting Salicornia europaea L can improve its saline-alkali soil. Adding processed Salicornia europaea L can inhibit the growth of chladophora in that chladophora stunts the growth of Hydrilla Verticillata through the scramble for oxygen and sunlight.

Site Analysis In the north of the site, it is a salt pan with an excessive content of salt and alkali, which is suitable for the growth of Salicornia europaea L. In the middle area, Xuanhui River is polluted greatly. The south area has a reservoir with frequent appearing of chladophora as well as excessive fluorine ions in water.

Regional Land Use

Samphire should be irrigated with salt water. However, the surface water in this region is fresh water, which cannot be used to irrigate Salicornia europaea L .

Xuanhui River, a saltwater river with flood seasons in this region, can irrigate the S a l i c o r n i a e u ro p a e a L i n saline—alkali soil. But the water reservoir nearby has excessive fluorine ions and massive chladophora, which leads bad water quality.

Forming Reasons of Salt-Alkali Soil

Effects of Salt-Alkali Soil

Special Species

There is a small runoff volume and a large evaporation capacity Local saltworks excessively pumped underground brine.

The irrigation of flood did not get drained in time.

High level of underground water results in serious salt accumulation in soil.

Seawater intrusion pollutes underground water.

Excessive salt accumulation exacerbates the soil in physical properties.

Plants cannot absorb enough water form soil. Carbonate hinders protein synthesis, which leads to the death of cells.

Salicornia europaea L

Hydrilla Verticillata

The root of Salicornia europaea L can validly improve salt-alkali soil.

Hydrilla Verticillata can absorb the fluorine ions in water to purify the water.

Seasonal Variation Of Salicornia europaea L

Master Plan The artificial river bank, which is used for flood prevention, will be rebuilt as natural ones to improve the local biodiversity through Salicornia europaea L irrigation.

Hydrilla Verticillata is processed as pesticide to reduce the damage of inchworms.

Inchworm grows with Salicornia europaea L together, during which it takes the leaves of samphire as food and then leads the death of Salicornia europaea L.

The shells of shrimps and crabs can produce calcium ions to combine with fluorine ions and generate CaF2 sediment, reducing the fluorine ions in water.

The water with excessive fluorine ions can breed aquatic products like shrimp, crab after purification.

04. Crisis Of Biological Invasion

Enhancing the stability of marine ecosystems to resist the invasion of alien species Year: 2017, Individual work

When human activities give rise to a crisis in the ocean, the warming of the ocean becomes extremely dangerous. As a result, the originally nonnative creatures floating in the ocean from the hot to the cold water areas, could lead to an unpredictable disaster for the ecosystem along the west coast of the Pacific. The study of the biological nature about invasive species, pyrosomes, found that, the blue light emitted by pyrosomes can promote the growth of coral larvae and then produce new coral reefs. As a breakthrough point, the pyrosomes are gathered with the help of a device and tide in a controlled range, to feed the local endangered dermochelys coriacea, and thus the quantity of pyrosomes is controlled. In the meanwhile, it also provides shelter for living things and helps recover the stable ecosystem in the ocean, so as to resist the crisis of biological invasion that damages the local ecosystem.

Site Analysis The site is located on the coast of Columbia, in the province of British Columbia, Canada. Along the global warming of oceans, Pyrosomes float from the hot to the cold water area, which results in an accumulation on the coast of Colombia, and it would not only affect the local fishery, but also destroy the already fragile ecosystem of Canada. At the same time, under the premise of global ocean acidification, coral reefs also face the crisis of coral bleaching.
