The Handan Wastewater Purification Terraces
The Handan Wastewater Purification Terraces is located in the suburbs of Handan City, which was completed in 2020, covering an area of 10 hectares. The “wetland terraces” is a reclaimed ecological water purification demonstration project, which belongs to the wetland conservation area of the 4th Horticultural Exposition of Hebei Province. The design takes “landscape Handan, green revival” as the theme and repair the soil and water pollution caused by long-term garbage stacking. Designer adopt modern design language, combine the advanced concepts of sponge city and smart technology, and jointly build a Green Garden Expo integrating mountains and rivers.
Water Environment Treatment of Beihai National Wetland Park（Fengjiajiang Watershed）
Beihai Coastal National Wetland Park was completed in Beihai City, Guangxi Province. It is an important ecological corridor in Beihai city, covering 446 hectares. The design fully implements the concept of “Mountains, waters, forests, farmlands, lakes and grasslands are part of a community of life” proposed by the President Xi, coordinating water environment system treatment projects to realize the pollution control and ecological restoration. Restore reservoir-river-coast compound wetland system, rebuild green lung of Beihai.
Fish Tail Park in Nanchang City
In the city of Nanchang, within the Yangtze River flood plain in east-central China, we transformed a 55.6 hectares badly abused landscape into a dreamlike floating forest that regulates storm water, provides habitat for wildlife, offers an array of recreational opportunities and gives local residents a new way to connect with nature. All of this lent a unique identity to the New District and served as a catalyst for urban development in the surrounding area. Fish Tail Park offers a replicable model of designed urban nature for regions with monsoon or variable climates that can address the multiple challenges of floods, habitat restoration and recreational demands.
Sanya Mangrove Park was completed in 2016 and covers a total area of 28 hectares. Concrete flood walls were built to claim land for development that killed the mangroves. A land form of inter-locked fingers was designed to lead ocean tides into the park. Making use of the 9-meter drop from the urban road to the water level, terraces are integrated with bio-swales to catch and filtrate the storm-water from the urban pavement and road. Just three years after its construction, it has achieved the goal of restoring mangrove habitat and meeting the recreational needs of citizens.
Sanya Dong’an Wetland Park
Sanya Dong’an Wetland Park covers an area of 68 hectares and was completed in 2016. It was a wetland on a river corridor that had been filled with urban debris. The water was polluted and the wetland was degraded and overgrown with invasive water hyacinth (Eichhornia crassipes). The plan calls for more space for water, and for removing the concrete flood walls that had channelized and reduced the resiliency of rivers, replacing that hard infrastructure with eco-friendly embankments. At the periphery of the park, a porous landscape composed of dykes and ponds of different depths creates a diversity of habitats that retain and clean water and nourish rich biodiversity, including native birds, fishes and amphibians.
Qian’an Sanlihe River Ecological Corridor
Located in Qian’an City, Hebei Province, the Sanlihe River uses landscape to revive and construct both existing and new city infrastructure; it is capable of reducing pollution, providing opportunity for urban land development, and serving ecological functions Covering approximately 135 hectares, this ecological corridor stretches 13.4 km in length and varies 100-300m in width. Within this linear park, water is diverted from the Luan River, through the city, before returning to Luan River. Through two years of design and construction, this project has transformed this seriously polluted landscape back to its previous splendor as a scenic urban ecological corridor “where reeds and locus flourish and water abundant with fish and soft-shelled turtles”.
Qinghuangdao Beach Restoration
The project is located in Qinhuangdao City, Hebei Province. It was completed in 2008, with a length of 6.4 kilometers and a total area of 6,000 hectares. The previous development and construction destroyed the seaside wetlands, resulting in degraded vegetation and deserted beaches. The design applies “Ecosystem Services”, using a variety of ecological restoration techniques, to restore a beach that has been disturbed by erosion, degradation and human development activities into a popular place for people and birds.
Jinhua Puyangjiang River Corridor
The Jinhua Pu Yangjiang Ecological Corridor covers an area of 196 hectares and was completed in 2016. “Crystal” industry destroys the Puyang River. The designer uses ecological water purification, ecological management of rainwater and flood, adaptive design that is friendly with water, and landscape strategy with minimal intervention, combined with ecological restoration of hardened river embankments, transformation and utilization of agricultural water conservancy facilities, and integration of safe and convenient slow traffic. The network has completely transformed the severely polluted river into the most popular ecological and living corridor for citizens.
Chongqing Tang’nan Dafo Temple Wetland Park
The project is located in the center of Tongnan District, Chongqing, covering an area of 99 hectares and completed in 2019.Aims to create a “riverside beach–the return of the Fu River wetland”, the design team preserves the wetland of the river as much as possible, compresses the boundary of the city balcony, and sets up a walking corridor, thus providing visitors with a rich and sensory experience. Taking the vision of “take a boat ride down the river alongside the flowery dyke, thousands of mountains emerge in the haze”, the team activates two key cultural elements of Tongnan: the long-established shipping culture, and the Buddhist culture based on the Dafo Temple, and creates a city riverside wetland landscape park with local cultural character.
Harbin Qunli Stormwater Park
The project is located in Harbin, Heilongjiang Province. It was completed in 2011 and covers an area of about 30 hectares. The design starts from solving urban problems, utilizes urban rainwater, transforms parks into urban rainwater parks, and makes natural wetlands the natural ecological infrastructure of the city, thus providing the city with multiple ecosystem services: it can collect, purify and store rainwater , the rainwater purified by the wetlands replenishes the groundwater aquifer; the infiltration of rainwater can make lush local habitats multiply in the center of the city; at the same time, through ingenious design, the rainwater park can become a good place for citizens to rest and drive the city’s develop.
