The city and the countryside have had a natural bond since the beginning, with the two being interdependent and organically linked. In the long history of traditional agrarian societies, the relationship between urban and rural areas has taken various forms, but the symbiosis and interaction between urban and rural areas has undoubtedly been widespread. The urban archetype of 'city, town and countryside' was then formed, and as the division of labour became more refined and the functions of cities became more sophisticated, the boundaries between the three became blurred. The boundaries between the three became blurred and the division of functions within the social system became increasingly fragmented.
Therefore, we propose new ideas and concepts that are in line with the sustainable development of modern cities in social systems. In order to achieve a dynamic and harmonious social system, and to ensure that urban people do not forget the beauty of the countryside and that rural people no longer simply supply food to urban people, we propose a new low carbon social system network with "agricultural waste" as the main relational glue.
With regard to the paradigm of urban-rural integration, the combination of city and countryside has never been just a one-way combination, but a network of social systems formed by links between countryside and countryside, city and countryside, and city and city. As functional subdivisions in cities continue to be refined, the economic ties formed between cities have contributed to the rapid development of urban agglomerations, while the pace of development between countryside and countryside, and between countryside and city, has lagged relatively behind. In the urban-rural relationship, the city has always played the role of the 'aggressor' who constantly demands food, land and other resources from the countryside, while the large amount of agricultural waste generated in the countryside, which has to be disposed of by burning and burying, continues to affect the countryside in every way.
We propose the idea of 'bringing agricultural waste from the countryside into the city' and build a complete system of waste reuse to minimise carbon emissions and make the best use of it. This inspiration is a way of repaying the city's waste for its encroachment on the countryside, bringing the goodwill of the countryside to the city to think about its own development.
At the beginning of the study, six city prototypes were selected for discussion from cities in the provinces through which the Yellow River flows, and we finally settled on Zhengzhou City, Kaifeng City and Zhongmou County in the middle and lower reaches of Henan Province as city prototypes for the study.
A site analysis of the area is carried out, with the Yellow River as the boundary, and to the north of the Yellow River is a rural agglomeration of mainly traditional agriculture, while to the south of the Yellow River is a prototype combination of cities and towns represented by 'Zhengzhou City - Zhongmou County - Kaifeng City', in order to study the potential for future urban-rural integration in the area.
During the opening phase of the project, the team members once again read deeply into the official theme, the context of the competition, and the architectural work and design ideas of the competition's jury chairman, Tom Mayne. The design was based on Tom Mayne's view that urbanisation has become a very urgent issue, and in the context of the competition, we were able to clarify the design intentions and start the design work.
Firstly, the existing contradictions of the site were analysed and the 'agricultural waste' from the countryside north of the Yellow River in the area was classified according to the time of cultivation, the type of agricultural residual waste, the method of degradation and decomposition, etc., so that the design could be theoretically supported. The feasibility of using the agricultural waste as a building material after treatment is determined, and the spatial form of the material used is then considered in relation to the local characteristics to ensure that the scheme can become an urban 'example' while preserving the historical and cultural characteristics of the different cities.
Based on previous research into agricultural materials and green materials, the agricultural waste from the site is divided into rice husk, straw, mycelium and algae materials, starting with the crops in the area. The methods of recycling and reprocessing are explored, mainly by shredding, mixing, burning, pressing and soaking. Through the different treatment methods, the different materials have different properties, and their functions and forms are explored according to their properties.
The result is a new low-carbon social system network with "agricultural waste" as the main binder of relationships, from the disposal of "agricultural waste" in the countryside north of the Yellow River, to the specific processingof the material in a county in a town south of the Yellow River and the diversion of the material to nearby cities.
This entry is a reflection and exploration of the relationship between the city and the countryside. Is the countryside a dependency of the city? Is the countryside a dependency of the city? Or is it a source of resources for the city? We believe that the relationship between urban and rural areas is both mutually beneficial and mutually restrictive, both urban and rural areas are facing the huge environmental pressure brought by waste. It will become another link between the city and the countryside, promoting equality and reciprocity between the city and the countryside, the beauty of each and the sharing.
