This is a project featuring a wetland park and a high-tech office area, with a design area of about 50 hectares in south China. The original site faces the risk of external flooding and internal waterlogging from the adjacent Changshan River to the north, with extremely poor water quality. The original site ecological texture features the agricultural ecosystem of "Mulberry-Dyke-Fish-Pond", a peculiar and scientific agricultural ecosystem in the Yangtze River Delta. We fully respect these unique features, preserving the trees on the ponds, and partially opening up the fish ponds to create interconnections between them, allowing for the exchange of biological organisms. We also introduced water from the Changshan River to maintain flow and planted plants with water purification functions, such as Phragmites australis, Typha orientalis C. Presl, Thalia dealbata Fraser, Arundo donax var. versiocolor Stokes to cleanse the water quality. Through sustainable design methods that are tailored to local conditions, minor modifications are made to the existing site to reconstruct the ecological environment, creating a wetland park with rainwater storage and water purification functions, and providing a lush ecological backyard for the technology enterprises settled in the southern part.
We have implemented low-impact development technologies for the office park. By combining the use of 1112.75㎡of sunken green space, 2543.43㎡ grass swale, 8009.61㎡ permeable pavement and facilities for rainwater collection and reuse, we enhance the water environment of the site. These measures ensure that the Annual Runoff Volume Control Rate within the project reaches 84.2%, the Comprehensive Rainfall Runoff Coefficient hits 0.45, and the Non-point Source Pollution Reduction Rate (measured as SS) reaches 54.73%. This approach alleviates the pressure of rainwater and flood management in the area and builds a demonstrative project for sustainable development that both adapts to climate change and responds to social responsibilities.
