The project proposes a series of innovative urban strategies to address how neighborhood spaces will be developed in urban communities after Covid-19. Through the in-depth study of the urban model of “Linpan” in the 1980s in Sichuan, Chengdu, it is found that this model has succeeded in creating a kind of high efficient self-sufficient community. And it is very suitable for solving the situation of community-based isolation formed continuously after Covid-19, which can greatly reduce the economic losses caused by Covid-19 and meet the social needs between the communities. The model is therefore innovatively adapted so that it can be applied to the present and the future with the development of urbanization.

Reconnecting the “Mengzhuiwan” to the Central City -- Urban Methodology Study for TOD (Transit Oriented Development) System Designer: JIAJUN ZOU, YUCHENG FENG, FULE MA Location: Chengdu, China Year: 2020/ the sixth semester Group work(My job: TOD research and strategy and planning , analysis, effect drawing,green planning) Academic study Southwest Jiaotong University Instructor: CHUANLIN YANG
" Transit enhances the overall economic efficiency of a city, which has double the economic benefit to a city than does highway investment. " -- From Sustainability and Cities, by Newman & Kenworthy The project is located in Chengdu's busiest central area, surrounded by sophisticated commercial district and office building. However, the site has abandoned factories, old uninhabited houses and unspoiled houses all year round, so it has gradually become a crime-prone site. Over time, the site's traffic declined and it became an isolated island in the heart of the city, away from this flourishing city. Therefore, the project solves this contradiction by learning the TOD（Transit Oriented Development） system to reconnect this waste site into the city centre. And it has designed three low-carbon forms of transport, including a "Cloud Rail" for tourism, a "Smart Capsule Buses" for office systems, and a "Skyline" for commercial systems. These three proposals run at the same time and cooperate with each other to meet the need of dailylife for citizen. They also breaks through the traffic jam caused by the abandoned land in the central area, stimulates the commercial development in tourism, office and shops to reconnect with the original prime location. That can revitalizes this land, and then it will bring huge economic benefits to the city in the future.
WHY TOD SYSTEM CAN BRING BENEFIT TO THE CENTRAL AREA OF METROPOLIS ?
Investment in public transport brings much higher economic returns than investment in the highway. Kenworthy and Newman (1999) said that economic benefits brought by public transportation to the city are twice as highway investment. It means that TOD (Transit Oriented Development) allows the city to be guided by the traffic corridor, putting fewer infrastructure services a greater range of people. Besides, the joint development of station commercial complexes can greatly increase government revenue (Figure 1).
Figure 1: drawing by the author
TOD increases mobility and aggregation of the communities among various people. In other words, the gathering of people will promote the development of the business format, including office, entertainment, business, and so on. The enrichment of business format can improve the community economy. After that, a higher known community can drive economic benefits of the surrounding community, which forms a chain reaction. The chain reaction created by TOD can take place in many places of the city, and form a huge urban economic network to improve the economic benefits of the city (Figure 2).
TOD's public transport system can effectively help cities achieve carbon neutrality. Take an example, Feng (2006) pointed out that after 90km of bicycle lanes were added in Copenhagen, the number of people choosing to travel by bicycle increased by 65%, That is to say, after the improvement of public transport facilities, people are more willing to choose low-carbon travel modes such as bicycles and buses. What’s more, in the United States, the use of buses reduces traffic congestion. When the bus system is developed, the efficiency of buses is higher than that of private cars, so people will choose buses, and the carbon emission of buses is much lower than that of private cars.However, too many bus or bike stops have their limits. Bus stops will attract other vehicles such as private cars which will lead to traffic jams. For example, The retail point near the station will attract people and vehicles. Therefore, I believe that adjusting the frequency of bus departures can improve traffic efficiency rather than adding more stops.
The Chengdu government has been supporting the introduction of Tod to the city. I found a lot of waste blocks when investigating. These waste blocks are mostly in the downtown area, thus reducing the vitality of the downtown, not only do these blocks become crime-ridden, but they also create congestion. So I chose “Mengzhuiwan”, trying to transform this place with TOD's methodology, to reconnect this area to the city.

Capsule bus routes are designed for office systems. The number and timing of bus dispatches will change flexibly with the needs of users. During peak commutes, there will be additional traffic on routes passing through office buildings, while other times also can meet daily traffic needs. Users also can book bus arrival times via the mobile app.
A "CLOUD RAIL" FOR TOURISM
“Cloud Rail” are designed for tourism. The system connects the city's bike paths and sidewalks, connecting the riverside park and the site along the way. It is designed as an undulating bridge that separates bike paths from sidewalks, which allows tourists can walk down to the ground or park at any time. Barrier-free access is available every 200 metres.
A "SKYLINE" FOR COMMERCIAL SYSTEMS
“Skyline” are designed for commercial systems. The system connects commercial buildings on the ground. The building entrances on different floors are also connected. Form walking trails, commercial spaces, and public spaces connect vertically.

Designer: JIAJUN ZOU Location: Chengdu, China Year: 2021/ the eighth semester Individual work Academic study Southwest Jiaotong University Instructor: XIZI TANG
The Min River is a river flowing from the Qinghai-Tibet Plateau to the Sichuan Basin, and its upper reaches are one of the important sources of the Yangtze River. It is the one of the highest-level rivers in the Yangtze River water protection. However, the Minjiang New District, located at the overlapping tributaries of the Minjiang River Basin, is often affected by flood disasters during the flood season. The reason is that the river has a large amount of water during the flood season, and every year the government will discharge the upstream reservoir. As a result, residents of this area are often in a state of relocation and construction of temporary homes, while economic development conditions in the area are hampered by flooding. To address this, the aim of the project is to enable new cities in the region to adapt to the effects of the flood season, reduce overrelocation, and increase the social vitality and economic development of the region. From an ecological point of view, the use of artificial spruce forests, understory debris and moss layers, these three locally suitable ecological restoration methods, and the introduction of the concept of urban biomass squares. Finally, it create a new type of Minjiang community. The community was able to adjust the dynamic balance of the water conservation capacity of the land in response to changes in water levels.
A large number of rivers converge here, forming floods, but the city's hard pavement, flood hoarding can not replenish groundwater.

The concept of this project is to revive a local drama named “Qinglinkou highrise drama". This drama is currently facing a great challenge that quite few people willing to enjoy it due to located in rural area with poor condition as a performance space. By renovating the functional form and redesigned the building, and creating interaction points between tourists and villagers to guide tourists to the stage and auditorium through a series of nodes, so that tourists and villagers can not only have a better experience of the show but also revive the drama itself.

A Revival Again The cadres of Bai Yu Village firmly believe that the harvest can get rid of poverty, inviting professors to guide the crops, and finally got rid of poverty.
At The Beginning Of The Han Dynasty The villagers worship the statue, and stepped on the hillside into a flat land, and it was called Tang Jiaping.
1957 Origin of Village Name In 1957, the villagers took a large White jade in Baiyan, therefore named Bai Yu Village.
Now Culture Disolation The inheritors of “Qinglinkou’s high-profile” opera were getting old and young people were not interested in it. The culture of this ancient show was slipping away.

Becoming better known Bai Yu Village was rated as a provincial-level advanced grassroots party organization, as well as excellent cultural protection units. Attracted a large number of tourists.
The rural commune is transitioned to the senior commune, and established the Tangjia Party Branch.
The six tourism nodes gradually increase the interest of tourists in the high-lift drama. At the end of the node, the sloping roof house is extended to the ground to form a staircase that people can freely go up and down as seats. People can sit at different heights during the high-rise drama performance to get the experience of this ancient art from different angles. In addition, the function of the building was not only provided a place for tourists and villagers to interact, but also along with the cafeteria; small scaled gallery and accommodation and etc. to better serve as the public gathering space.
FIELDTRIP RECORDSTING PROBLEMS
EXISTING PROBLEMS I wanted to experience the country life, but here are all European-style buildings, and the country atmosphere is gone.
I wanted to use the “Qinglinkou’s high-profile”opera as my design inspiration, but unfortunately I didn’t see the performance after coming several times, and I may not come again in the future. A large number of laborers in the village go out, and no one want to keep play “Qinglinkou’s high-profile”opera. Nowadays, few people know the existence of this opera.
In recent years, the number of performances has become less and less. There are only once or twice shows per year. The “high-level performances” are almost forgotten by the villagers.
SEEKING FOR INTEREACTION POINTS
Through the research of the main routes in the village, I found that people flow in site area is very small due to the Public service facilities are mainly concentrated near the government, which takes 25 minutes walking form the site. The buildings around site are mainly three-story Europeanstyle that is irrelevant with local culture itself.
As the part of the most important spot in the village, the site building should play a role in highlighting Rural features and the role of rejuvenating rural culture.
TOURISM NODE PLANNING
FUNCTION PARTITION
The exhibition hall serves to increase tourists' desire by Inserting six activity nodes between the entrance and the building. The observation deck allows people to get the great view on farmland. What’s more , tourists can also visit the agricultural farmland to have the experience such as fruit picking. The rest area allows visitors to kill the time while waiting for the next performance, and they can sit on the sloping roof to watch the performance and even stay overnight.
