Abstract
Pocket parks are small public spaces between building entities which are available to the public. It can be located in a city, suburb, or country. It has a small area and is relatively flexible. According to the characteristics of China's cities, this article puts forward methods and measures for the landscape reconstruction design of existing urban communities in China. The thesis takes a Residential area of a certain district in Wuhan as a design case. It discusses how to combine the landscape design of the existing community with the rainwater problem, the goals, principles and measures of the landscape reconstruction design of the existing community based on the sponge city concept are proposed. Using rainwater as a resource to collect, purify, store, and recycle, alleviate water shortages and urban flood disasters, and it summarizes the methods and strategies for landscape reconstruction design of existing communities. Finally, according to the problems in the residential area and the actual needs of residents, combined with the current conditions of the site, following the design principles of people-oriented and local conditions, the use of sponge city technology measures on the green landscape, roads and parking lots, rooftop landscape of underground garages, plants Matching and other specific reconstruction designs provide theoretical and design references for the application of the "sponge city" concept in the design of urban residential quarters.
Highlights
The Ministry of Housing and Urban-Rural Development issued the "Sponge City Construction Technology Guide", so the definition of the concept of "sponge city" is very clearly
It can be located in a city, suburb, or country. It has a small area and is relatively flexible. In foreign countries it is usually built on vacant plots of land or buildings, or it can be created as part of the public space requirements of large construction projects
The rainwater runoff in the green space will be collected into the cover plate infiltration ditch through the overflow port when the rainfall exceeds the standard, and the excess rainwater will eventually be merged into the pump well through the connecting pipe and temporarily stored in the pump well for the later greening
Summary
The Ministry of Housing and Urban-Rural Development issued the "Sponge City Construction Technology Guide", so the definition of the concept of "sponge city" is very clearly. The city which is like sponges, it has good "elasticity" in adapting to environmental changes and responding to natural disasters It absorbs, stores, seeps, and purifies water when it rains, and "releases" and uses the stored water when needed. In January 2015, the sponge cities were started to construct in 16 pilot cities including Zhenjiang, Jiaxing, Xiamen, Jinan, and Wuhan In foreign countries such as the United States, Japan, Australia, and some European countries, the practices of urban water resources management started earlier. They proposed "BMPs Best Management Practices", "LID low-impact development technology", and "WSUD water-sensitive urban design." The concepts have been well applied in urban planning and design, and can provide good references for our country. 2 Design principles of residential quarters based on the concept of sponge city pocket park
