The wetland park is located in the ecological leisure area of downtown Wuhan East Lake Scenic Spot. Within a radius of 5 kilometers, it is surrounded by many interactive attractions, such as OCT Happy Valley, Ecological Art Park, Donghu Tingtao Scenic Area, Beach Bathing Place, etc. Due to the failure of the water circulation system, the existed wetland park had serious eutrophication, fewer birds and lower air quality. Citizens or tourists seldom visited the park.
This project was given special significance at the very beginning in this special Post-pandemic Era with its special geographical location. How to restore the ecosystem and bring people back to the park after the epidemic became the key to the design.
"The interdependent relationship always exists between human and nature. We are part of an ecological chain, and our dependence on the natural public space cannot be ignored." The design team kept in mind the law of respecting nature and put ecological restoration in the first place of design.
In the existed project site, silt accumulation and algal outbreak caused serious eutrophication. When the problems have been identified, the design team discussed with the water treatment company and decided to renovate the existed revetment. By adding a new lift pump, the first physical water purification barrier was added in the refill area. After that, the water will pass through the submerged plants and the emerged plants area for secondary purification. Finally, it will reach the south purification zone and settle down. After the physical and biological purification treatment, East Lake IV class water is transformed into II~III class. Depending on the gravitational potential energy, the purified water will be absorbed into the aquatic plant area on the west side.
After purification, the lake becomes clean and sparkling, the green plants reflected clearly on the water. The sparkling lake water, together with safflower trees and camphor trees, forms a scenic spot like the beautiful oil painting. The pleasant scenery makes tourists forget their worries and enjoy themselves in this green world.
The clear water provides an excellent habitat for living creatures, a group of fish swimming freely in the lake, the ducks flapping their wings and making ripples on the water, from one end of the lake to the other.
Submerged, floating and emergent plants, as well as ecological islands were added in the purification zone. Plants with the popularizing science function were planted In the west aquatic plant exhibition area. In addition, designers redesigned the revetment, enriched the aquatic plant species, and built the water purification system a stable wetland plant community, so as to optimize the ecological environment and increase the interactive interest of the park.
Cannas grow closely together and are naturally integrated with stepping stones. The winding water walkway is surrounded by lush vegetation. The birds sometimes skim over the water; sometimes stop on the branches; sometimes glide in small groups on the lotus leaves.
There is no difference between people except their skin color. We respect nature and also pay attention to people's needs. Using the natural environment as the canvas, the designers added more colors in the green forest to form the visual impact, thus arousing people's desire to play.
People's first impression of the landscape design comes from vision, from their eyes. Color change also has an important impact on people's emotional changes and psychological activities.
With the principle of low cost and low impact, designers chose to transform the original mottled bridge by changing its color. By painting a rainbow, L&A Design returned vitality to the green wetland park and bring the visitors a pleasant experience. Parts of the bridge deck were changed to bamboo and wood paving, to increase people's walking comfort. In addition, a bird-watching platform was added at the node of the bridge to meet visitors’ basic viewing needs.
We heal the soul by painting a rainbow in nature. The blue sky and white clouds reflect on the lake. The colorful bridge passes through the cedar grove, leaving a gorgeous reflection on the water. Varying colors of the rainbow bridge fade with steps and gradually disappear at the exit.
To protect the birds in the wetland park, and to meet the basic lighting needs, anti-glare low illumination was designed to provide pedestrian lighting without disturbing the animals and plants. Night is falling, the moon staying bright in the sky. Clouds is disappearing, secretly falling to the earth. The moon and the rainbow lit up the whole park. The moored boats, rippling in the green waves, guard the beauty and splendor above.
The existed waterfront pavilion was repainted to create an extreme contrast between strong red color and surrounding abundant green. The color contrast attracts visitors very much. In addition, the rest seats were also added to attracts people to enter and play with water.
Illuminated by the light, the pavilion is plated with a shallow halo, like a picture frame for the surrounding landscape. It is an ideal corner to sit and chat with friends near the lake, feeling and touching the cool breeze. The night here is gentle and tranquil.
Come from the nature, and go back to the nature. Landscape design opens a window for human and nature, bringing us closer to the nature, feeling her, getting to know her, and playing with her.
Based on the principles of respecting nature and low impact, the design team renovated the facade with bamboo and wood. Part of the pavilion was opened to form a bird-watching window. The top of the pavilion has been redecorated and seats was added to create a space suitable for people to have a rest. The bird-watching pavilion is redesigned with dual functions of bird-watching and science education.
The design combines the sky viewing platform with the rainbow corridor. Visitors could enjoy a panoramic view of the park through the newly set telescopes.
The water curve sprayed on the ground with luminous paint increases the visual sense of movement and improves people's walking interests. The curve combined with the ground signs form a new guide system, which enhances the interaction between people and landscape.
The formerly uninteresting landscape avenue has been revitalized through the renovation. The white streamline not only breaks the monotony, but also extends people's vision and create more eye-interactions between visitors.
A micro topographical landscape was designed, integrating with the ground paint line. With the undulating rainbow bridge as the background, the designers not only decompose the space, but also enhance the interaction between people and the site.
Since the restoration and protection of the natural environment is the top priority, L&A Design focuses on restoring the water ecosystem and establishing an ecologically sustainable water purification system in the renovation of Wuhan OCT Wetland Park. Through the use of color design, the designers add more vitality to the park. In addition, through the addition of interactive installations, L&A Design not only enhances the functionality of the park, but also gives the park a modern, lively, ecological and natural spatial image.
Everything in the nature is connected and circulates with each other constantly. The nature embraces all colors. We live with the nature, and through the vicissitudes and the wounds of disease, we learn more about the importance of respect. Designers believe in the nature. The nature will also become our best reliance.
