Qianhai Water City’s First Waterway Promenade Park

SLADI/JCFO

Short description

PROJECT STATEMENT
Qianhai Guiwan Park is located in the heart of Qianhai district in Shenzhen, China. It is north of Guiwan Business District, south of Qianwan Business District, and stretches from the Moon Bay Avenue to Qianhai Bay Coastal Park in the west. It is a brand-new central urban park.

Based on the eco-development framework of "Qianhai Water City", which proposes five linear waterway parks called "Water Fingers" as part of the new city's ecological development, the project is the core of the development. The difficulty of the project lies in the lack of vitality, poor water accessibility due to flood prevention embankments, and severe water quality problems.

The project takes water as its core and creates a rich ecological base through terrain shaping and diverse vegetation planting. The embankments are softened, and three-level terraces are built for waterfront spaces and respond to tidal changes. The project creates a network of urban vitality by creating a habitat for harmonious and interactive wildlife, linking the city and the park.

After completion, this place is not only a leisure park and green space in the city, but also an effective urban ecosystem to improve water quality, air purification, and residents' quality of life.

CHALLENGES
The original flood prevention canal in Guiwan Park was straight and rigid, and the high salinity and eutrophication of the water quality were the first challenge in purifying the project's water quality. The second challenge was injecting a lively atmosphere and cultural life into a deficient environment while creating a continuous vitality network. The third challenge was creating a mangrove ecological wetland in a unique environment where saltwater and freshwater intersect and completing the essential functions of flood prevention, tide control, and drainage.

STRATEGY
The project aims to combine urban lifestyle and ecology. It creates an urban ecological park by enriching the activity space with diversified spatial design and abundant vegetation, using the ecological environment as the park's foundation. The embankment is softened to reshape the river, creating a more diverse shoreline ecosystem. Multiple terraces are built on the natural terrain as a buffer for flood control and water purification.

The park is built as an urban ecological park using tide changes, sponge facilities, and diversified canopy systems. The park presents a lively mangrove wetland ecological landscape, increasing biodiversity. A mangrove ecosystem of 50,000 square meters is created to purify the water and attract various benthic animals such as fish, shrimp, crabs, and snails to breed and, in turn, attract various birds.

The project links the park's interior, both sides of the river, and the surrounding city, allowing the park to complete ecological restoration and host various enjoyable landscape activities, meeting the needs of the residents' lives and the city's development in the Qianhai area.

URBAN FOREST
Guiwan Park is an ecological park with tidal waterways and urban forests. The park design is based on maximizing ecological functions and creating a diverse ecological environment by building different habitats in different park areas, such as mangrove wetlands, freshwater wetland gardens, tropical forests, leisure birch forests, and palm forests. This creates different microenvironments and diverse species habitats, truly achieving the effect of an "urban forest."

Ecological Base
The mangrove wetland in Guiwan Park softens the park's shoreline by combining with the tidal patterns of Qianhai. Within the 51,300 square meters of the mangrove ecosystem, red mangroves such as Aegiceras corniculatum, Rhizophora stylosa and Avicennia marina are planted in the low tidal zone (0.65-0.8m). Aegiceras corniculatum, Avicennia marina, Rhizophora stylosa, Kandelia candel, and Acanthus ilicifolius are planted in the middle tidal zone (0.8-1.6m). And minor mangroves trees such as Heritiera littoralis, Pongame oiltree, and Barringtonia racemose are planted in the high tidal zone (1.6-2.5m) to purify the water and attract benthic species and birds to inhabit. At the same time, the remarkable adaptability of mangrove plants to high-salinity seawater soils has created a unique landscape and ecological environment for the seawater wetland.

The freshwater wetland is not affected by the tidal influence of the sea. By controlling the water level and flow of the wetland and planting various plants such as Thalia dealbata, Lythrum salicaria L., and Softstem bulrush, the wetland is enhanced with ornamental features while also having a certain water purification function. Combined with surface runoff management, an ornamental garden is created that purifies the water.

Vitality Network
While strengthening the ecological foundation, the park design aims to stimulate social vitality, including a series of facilities that integrate with nature, such as parent-child games, recreation and entertainment, and multifunctional outdoor theaters, to bring beautiful scenery and pleasant experiences to the citizens. A series of customized spatial areas are arranged in the park: the climbing paradise combines fashion elements, outdoor sports, and leisure spaces; various pergolas use mathematical logic to generate visual effects, and the twisting angles create an infinite play of light and shadow. The architectural facilities inject personality into the park through "lines + undulations", floating above the ecological foundation, creating a complete "spatial sculpture" for Guiwan Park.

SIGNIFICANCE
As the first large-scale linear park in Qianhai district, Guiwan Park has provided a model for restoring coastal environments, purifying water quality, and creating park spaces for Shenzhen city. The design is based on maximizing ecological functions, increasing biodiversity to regulate the environment, and improving water quality. As more wildlife inhabit in Guiwan Park, it further proves the vision of achieving biodiversity and brings a beautiful natural space to the city. The park injects vitality into the ecological space through special designs such as spatial sculpture systems, blending a series of facilities such as parent-child games, recreation and entertainment, and multifunctional outdoor theaters into the park. This creates a harmonious "Qianhai green core" environment where people and nature coexist. The completion of the project has activated the vitality of the surrounding city and attracted more people and organisms to settle here. It has not only achieved the ecological development of the core area of "Qianhai Water City" but also practiced ecological urbanism in China's waterfront space.
