Research on High-Density Urban Community Waterscape Design and EcologicalRestoration: Taking Culture Garden Community Renewal in Shanghai Yangpu District asan Example |

Abstract: |
Nowadays, China’s developing urban period has gradually shifted from urban
expansion to existing community renewals in city centers. Through two decades of continuous
efforts, the government advocates ecological and sustainable urban systems to make cities
more livable and friendly to citizens. The Chinese People’s Political Consultative Conference
recently proposes the formulation of The 14th Five-Year Plan (2021-2025) for National
Economic and Social Development and the Long-Range Objectives Through the Year 2035.
Objectives include building an ecological and civilized city, promoting urban ecological
restoration, strengthening old residents reconstruction and new urban community construction,
enhancing urban flood control and drainage capacity, as well as building sponge resilient
cities. As one of the frequently used elements in community landscapes, waterscape should
have significant values in terms of aesthetics, ecology, entertainment, and culture. However,
due to urgent issues like higher maintenance costs, poor performance, loss of functions, and
residential dissatisfaction with water features in high-density urban communities, community
waterscapes’ renewal currently becomes a general concern. It needs to be solved with a high
priority. In another point, researches bring about a challenge on achieving the balance of
aesthetics, ecology, and function of waterscape. As the city’s framework, residential areas
need both improvements in living environments and systematic management. The paper
discusses theories related to the resilient city and main approaches, and significant roles of
resilient water systems in urban stormwater management and ecological restoration. After the
research analysis, the paper finally focuses on applying modular waterscapes. In community
developments and renewals, modular waterscapes have three main advantages: the richness of
changes and unities, network management, and water safety guarantees during the epidemic,
which are of great benefits to the sustainable use of community waterscape. However,
approaches of modular waterscapes in communities still lack relevant researches in China.Building on the above literature reviews, this paper takes an early constructed community named Culture Garden Community in Yangpu
District in Shanghai as an example. Researches point out the problems of sewage overflow and natural ecology intervention in the rainy
season from community closure combined drainage system in early urban zones. A new reorganization model on the water system of this
community is proposed. The new proposed model puts forward a management model suitable for the community waterscape by sorting out
the existing problems of water systems in the Culture Garden Community. Namely, three modules are formed: the running water science
popularization module, the flexible rainwater regulation and storage module, and the water circulating and recycling module, to build a more
resilient and sustainable waterscape of the community. The new model proposes that existing abandoned waterscapes in the community can
be rebuilt as modular infrastructures to form a dense green network in the city. It aims to restore the city’s excessively disturbed ecological
environment, make the city more resilient, and form a livable environment where people can live with nature sustainably. This paper verifies
the feasibility and economy of modular waterscapes under the orientation of resilient water systems theories, and proposes a new city model
with flexible modular waterscapes through research methods of literature investigation, quantitative analysis. |
