背景 | Background
The project is located in Xishan District, the southwestern part of Kunming in Yunnan Province. Due to the plateau climate, Kunming has low clouds and clear water that are presented in various colors.The project borders Dian Lake in the east, Wuhua in the north, Anning in the west, and Jinning in the south. There are a few places of interest in the region, including Xishan Scenic Area, NieEr’sGrave, Dian Lake Sunrise-view Area, and Taihua Temple. The site is a 20-minute from the railway station and a 40-minute from the airport and high-speed rail station by car, which is located to the southwest of Kunming downtown, within the primary preserved region of northern section of the Caohai. There is a wetland landscape space adjacent to the Caohai and the site has well-developed infrastructures and excellent landscape advantages.
视觉展示 | Visual Effect
Enlarge the natural beauty and build landscapes in the surround natural scenery. By planning the entire plot, the project has established the space rhythm consisting of four parts, namely, Welcome Avenue, Winding Woods, High Flower Platform and Lakeside Grass Sea. By building the closed front field and open flower sea in the back field, the project has formed strong contrast of atmosphere. Landscape spots are not designed in the region. Instead, flowers, trees, waters and stones are used as landscaping materials and utilizes mountains, colorful clouds, and clear water are treated as the scenery to seamlessly integrate the natural scenery of grass sea with the project landscape. In this way, people can sit leisurely on the lawn in the sunshine, and enjoy the beauty of changing seasons on the plateau. At the same time, the tourists can feel the freedom in the nature and have the sense of belonging that combines relaxation and rest.
In the entrance, the enchanting curve landscape wall and two-level water falls are designed, which carry more natural and artistic atmosphere just like the swinging ribbons.
Winding paths – follow the stone path and flower stream to step into the natural scrolls of art. The water fall can be seen at the end of the winding path.
The winding pond reflects the sky like a mirror, producing the natural and fascinating scene.
The sunlight is cast on the stony pond and water falls. Together with the mist and cloud reflections, it produces more charming painting-like image.
The sight becomes clear after passing the clouds and mists. You feel like floating above the flower sea and staying in the scenery. The region of buildings leading to the grass sea becomes the back field of the landscape. Paths are hidden among flower sea, stretching in the winding way towards the wet regions. The winding paths in the flower sea adopt the glued stones and sleeper technology that carry rich fun of nature.
The roads are hidden in the flower sea, stretching in the winding way into the wetlands.
Standing in the Display Center and looking at the Caohai in the distance, you seem to be floating on the flower sea and standing in the scenery.

挑 战 | Challenges
a.The properties of site are urban public green space and a small amount of wetland.The area is about 25,000㎡，in the region, there is the original site of the old factory, and a large amount of concrete foundation and construction wastes.
b. The other challenge for the project is to clean up the garbage and backfill the planting soil, and to protect the existing plants and wetland status.As required by the urban management administration, all waters and surrounding native vegetation are strictly retained and only landscape development and purification are allowed to meets the requirements for the quality and function of urban landscapes.
c. The third challenge is how to rebuilding the bank and establishing an ecological land-water transition zone. Because of the ecological restoration, the design need maximize water purification and create lakeside landscapes in combination with ecological governance.
Based on different features of waterfront belt, wetlands belt and terrestrial transition belt and considering the living habits of animals and plants, the project rationally allocates proportion of plants to maximize the ecological benefits of the wetlands.
At present, most of the revetments are natural ones. The design focuses on ecological restoration to build the ecological transition zone from water to land.
设计策略 | Design Strategy
Considering the basic requirements for wetlands preservation and sponge cities， the remain abandoned buildings are dismantled and the sunken green space and water-permeable breathable pavement are installed in order to create a natural and ecological green space.In the site, there are a large number of old building residues and a large amount of construction waste. In order to ensure the soil quality in the green space and the growth of plants, the construction waste will be removed from the site in initial construction stage, and the soil will be backfilled with an average depth of 1.5m. In the process of site cleaning, arduous efforts were made to protect the existing plants and wetlands. Small machinery were used to gradually clean and protect the existing soil and vegetation to the largest extent. As required by urban green space regulations and those for sponge cities, 3,000 square meters of sunken green space has been built andall waters in the base and the surrounding native vegetation must be strictly preserved.
In terms of material selection, a large number of local slates are used to ensure these materials are ecology and environment-friendly and are integrated with the natural environment. Some pavementsin the wetland are paved with a large number of 6-8 gravels. The foundation is graded gravel and 300×100 plain soil on both sides of the road, which are used to compact the surface drainage ditch to ensure water permeability. The roads in the public green space use black slabs produced locally in Yunnan, with rough texture and clear texture, which blend perfectly with the natural environment.
Regarding plant use, protective trimming is made on the basis of the original wetland plants. The seedling species and the origin of the seedlings are all local native plants to ensure stable plant ecology. Point trees, winter cherry trees, and hackberry trees, etc. are planted in some important places.
意 义 | Significance
Ecological benefits: It makes a contribution to Caohai Wetland Park and form a first-class protected wetland around Caohai. It plays an active role in climate regulation, degradation of pollution, and protection of species diversity.
Social benefits: The project improves the urban environment and beautifies the urban landscape.The Urban WetlandsPark is the natural section with greatest aesthetic beauty in the periphery of the city. As an important part of urban development, the modern and artificial urban landscapes and wetland park constitute rich living environment with harmony.
Through the unique design concept and the craftsmanship method in accordance with the site selection, the final presentation is an ecological exhibition park that combines ecological protection, tourism and recreation, creative display, cultural display and other aspects.
