Rainwater management and landscape design of Haidian Street Square Individual work Location: Haidian District, Beijing Studio:Landscape Architecture Studio I Instructor: Zhang Wenying(zwy@scau.edu.cn)&Huang Sha(sh959@cornell.edu) Date: July 2020 Area: 4ha Many cities in northern China will face rainstorms in summer, especially Beijing.

Due to the development of urbanization, the city has suffered waterlogging caused by rainstorms for ten consecutive years. Taking this as the starting point, the open space of Haidian central street is selected for rainwater and flood management design, to increase urban green infrastructure to alleviate waterlogging.

The project enhances the site drainage capacity through the transformation of the terrain high in the north and south, low in the East and West and the lowest in the middle, and further carries out rainwater and flood management through green space, permeable pavement and reservoir.

Haidian District rainstorm 2016 Beijing News

Challenge

The site has suffered extreme rainstorms in the past ten years.

There is a lack of green infrastructure around the central street in Haidian District. There are many colleges and universities and office buildings nearby. The advent of rainstorms often causes waterlogging in the street and road damage, which brings a lot of inconvenience to pedestrians.

Drainage system broken

The urban drainage system of Beijing has been unable to bear the heavy rain discharge workload many times, which is one of the main factors of urban waterlogging.

There is a road with small traffic flow in the middle of the site.

Site context Traffic&Space

Pavement&Plants

N

Office building Residential area Green space Entrepreneurial base Shopping mall Hotel University

The site is close to the edge of the road, with a poor sense of boundary.

There are two kinds of parking lots on the ground and underground.

The pavement is difficult to bear the rainfall discharge when the rainstorm comes.

Roadsides are mainly decorated with flower boxes, which lack the ability to absorb water.

At present, the site is an open space, lacking functionality and ornamental space.

The traffic situation on the site is complex and chaotic, and pedestrians can't move at ease.

The lower beds at the edge of the site have no function of absorbing rainwater.

The roadside planting species are single and the plant species are not waterlogging resistant.

Defense to Adaptation

Actively responding to the problems of industrial pollution and SLR faced by Longxue island.

Individual work Location: Nansha District, Guangzhou Studio: Introduction to Ecological Conservation Instructor: Chen Chongxian (chongxian@scau.edu.cn)& Ni kexin(nicolandscape@126.com) Date: January 2021 Area: 3100ha My university is located in Guangzhou, so I have made field visits to many venues in Guangzhou at the undergraduate stage. As a coastal city, Longxue island in Nansha District, as an important granary in Guangdong Province, is in danger due to industrial heavy metal pollution over the years and the challenge of sea level rise in the future. This design is based on the present, looks back at the treatment of industrial pollution, and discusses the strategies to deal with the rise of sea level in the future, so as to improve grain production.

In the face of heavy metal pollution, land replacement, phytoremediation ,and ecological buffer zone are used to control it. And through the adjustment of dams, wetland construction, and farmland type transformation to deal with the rise of sea level.

Longxue Island 2005 Southern Metropolis Daily

Farmland on Longxue island is facing dual challenges of farmland pollution and SLR.

Reclamation process

N

Most of the area of the island comes from land reclamation, and the industry on the island continues to erode farmland and bring pollution to it.

Before today, farmland was heavily polluted by industry. After today, the rise of sea level will bring new challenges to farmland. In this time interval, we should do a good job in pollution control and sea level rise defense.

Rebirth of the Former Site

Comprehensive transformation of Hanyang Iron Works

Individual work Location: Hanyang District, Wuhan Instructor: Hu hao（huhaoclark@yeah.net） Date: June 2021 Area: 41ha My family lives next to Hanyang Iron factory. Our three generations have witnessed the rise and fall of Hanyang Iron factory for over a hundred years. According to my current experience, due to the development of urbanization and the increasing shortage of urban green space, Hanyang Iron Works has gradually transformed into a park for people's activities and has office functions at the same time. Therefore, how to coordinate the coexistence relationship between post-industrial sites and modern buildings and how to increase green public space have become the focus of my discussion.

I planed the park in six parts, replaning the road network, functional areas ,and new and old building functions of the park, then strived to integrate historical sites with modern style while ensuring the needs of various users.

The park planning is divided into six parts: demolishing old buildings, replanning road networks, dividing functional areas, adding new buildings, adding green public space and building a two-story corridor system.

Site attractions

Class I roads Class II roads

Demolished building

Step1: There are some abandoned plants with no historical value in the site,

which shall be demolished.

Step2: Class I roads are designed to connect the north and South blocks, and class II roads are set on the site.

Step4: A row of commercial buildings will be added along the North block,

and office buildings will be added on the basis of the original office buildings.

Step5: Add green public space . It is hoped that the increase of public space

will enrich the possibility of people using the site.

3.5-metre-wide corridor 2.5-metre-wide corridor

Step6: Set up two different tour corridors in the two areas.One is to enrich the tour experience of the park, and the other is to connect the shops on the second floor of the northern business district.

Design analysis

Masterplan

Through replanning, the site is endowed with various functions such as activities, office, leisure, commerce and viewing. The open space and the outdoor space attached to the building will be built into a green outdoor activity space. At the same time, the construction of the second floor corridor can also provide the dual functions of scenic spots and rapid passage.

Corridor analysis：The corridor in the commercial street is very modern, and the corridor in the site is more industrial.

Site model

A large number of green public spaces are set between houses.The new and old buildings are staggered, which retains the function of the old buildings.

Acrylic plate：New building Basswood board: Reconstruction of old buildings White cardboard: scenic spot

Public space is divided into three scales.

The auxiliary space of the building provides spare rest for office workers, and the square green space and site green space are used by surrounding residents and tourists.

In the three areas with architectural distribution, the combination of buildings with different functions will increase the richness of the park.

Characteristic industrial building It is the core scenic spot of the park.

Transformed building The transformation of old factory buildings has the industrial flavor and saves money.

New office building Increase office space capacity.

Combination of Longdong primitive farmland and new urban farm Individual work Location: Tianhe District, Guangzhou Studio:Landscape Architecture StudioII Instructor: Zhang Wenying(zwy@scau.edu.cn)&Liu chunzi(chunnnnnzi@gmail.com) Date: September 2021 Area: 20ha Due to the needs of the course, I conducted a semester-long research on the village in Longdong city. Urban village is the tear of urban development. Urban village residents are facing problems different from urban residents in all aspects. Rural areas have become cities. Where should farmers go? Facing this problem, I try to combine urban agriculture with traditional agriculture in the hope that farmers can be cost-effective.Through the introduction of modular buildings, the interactive space between urban and rural areas can be better popularized.At the same time, the integration of urban and rural areas can also benefit villagers, urban residents and the government.

Urbanization is eroding farmland.

Longdong community has gradually changed from a village to a city.

With the continuous invasion of cities, the farmland area of Longdong community has decreased by 50% in recent 50 years.

Due to urbanization, Longdong community has partly become an urban village and partly developed into a modern city, and only a few villages are still preserved.

This area is the core area of the win-win concept and is divided into upper and lower floors. The upper layer is the viewing area, and the lower layer is the interactive experience area. At the same time, the modular construction is also concentrated in this area. On the one hand, it can enhance the interaction between villagers and urban residents, and on the other hand, it can also attract residents' attention to urban agriculture.
