Huairou Tianyun home sponge transformation, as a demonstration ecological landscape of the transformation of sponge city in Huairou District, Beijing, is the core sublimation of Zhongguancun sponge City Engineering Research Institute's continuous practice of "sponge city concept and technology", as well as its exploration and construction of "public greening, parking, children's entertainment, elderly fitness, public leisure" and "sponge city" in the old community Another demonstration case of "5 + 1" mode, integrating ecological landscape, innovative technology, rain and flood management, and enjoyable rest, enables the residential area to give full play to the "elasticity" of nature, form an excellent ecological water system, and realize the good wish of meeting nature in the city.

General layout:
　　
According to the overall goal of community transformation (landscape improvement, function improvement, sponge demonstration), increase the rainwater infiltration pavement, repair the ground pavement, enhance the green space storage, increase the rainwater utilization facilities, improve the sponge system, transform the old landscape structures, improve the landscape function and effect, comb the landscape green space and parking facilities, and set up the permeable high bearing ecological parking lot.

Project value:
　　

The successful introduction of "5 + 1" mode sponge city reconstruction concept by Zhongguancun sponge City Engineering Research Institute brings new forms, new approaches, new experiences and feelings to the old community sponge city reconstruction, the space construction of ecological landscape, and the sustainable green life. At the same time, it fully combines the functional space of landscape with the rainwater and flood management facilities of sponge City, which is effective The green technology to meet the requirements of sponge city and the green means to meet the low impact of development have become the demonstration model for the transformation of sponge city in the old residential areas in the future, and have been implemented in other areas.
