Landpoint: The project is located in Xishan District, the southwestern part of Kunming in Yunnan Province. The properties of site are urban public green space and a small amount of wetland. The project is close to Caohai and waterside wetlands. As required by urban management administration, all waters in the site and the surrounding native vegetation must be strictly retained and only landscape development and purification are allowed to meet the requirements for the quality of urban landscapes. Considering the basic requirements of wetland preservation and the sponge city, the original old buildings are demolished，flowers, trees, waters and stones are used as landscaping materials and mountains, colorful clouds, and clear water are treated as the scenery to seamlessly integrate the natural scenery of grass sea with the project landscape. Upon completion, the project will become an important waterfront space and ecological green corridor in Kunming, which combine the ecological conservation, leisure and entertainment, tourism, cultural creativity, trade and exhibition. It is the premier ecological wetland park in China.
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. With Dian Lake Nature Reserve wetlands, Kunming is a multi-ethnic city. 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, Nie Er’sGrave, Dian Lake Sunrise-view Area, and Taihua Temple. The site is a 20-minute drive from the railway station and a 40-minute drive from the airport and high-speed rail station, which is located to the southwest of Kunming downtown, within the primary preserved region of northern section of the Caohai. To the south of Daguan Park and to the north of the South Bypass Tunnel, there is a wetland landscape space adjacent to the grass seawaters. The site has well-developed infrastructures and excellent landscape advantages.
民族蜡染是昆明最具代表性的工艺之一，也支撑和演化出了丰富的民族服饰文化， “彩色丝带”，既代表了昆明的多彩的视觉特点，映射出多样化的自然条件。设计灵感来源于彩色的丝带，曲径通幽，水利万物而不争，旨在期待生物多样性、民族多元化。前场通过婉转变化的曲线道路、景墙、水景和植物，划分出层层递进的空间节奏。 后场以纯净的花海衬托出主体建筑的纯粹，纯净的草坪与草海湿地相接。
Ethnic wax printing is one of the most representative arts in Kunming, which also supports the rich national costume culture. The “color ribbon” not only represents the colorful visual characteristics of Kunming, but also reflects the diverse natural conditions. The design is inspired by the colorful ribbons and winding paths, as well as the water that benefits all life without asking for rewards. The aim is to trigger biodiversity and ethnic diversity. The front field through the gently-changing curves and roads, landscape walls, water features and plants, produces the space rhythm featured by gradual movement. The back field uses the pure sea of flowers to set off the purity of the main building, in which the pure lawn is connected to the Caohai.

a. The properties of site are urban public green space and a small amount of wetland. It covers a total area of 25,000 square meters. In the region, there is the original site of the old factory, and a large amount of concrete foundation and construction wastes.b. The biggest challenge for the project construction 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 so that the region meets the requirements for the quality and function of urban landscapes.c. Rebuilding the bank and establishing an ecological land-water transition zone. Restore vegetation, restore habitats for animals and plants to enhance biodiversity ecological restoration, water quality purification, and landscape creation. Focusing on ecological restoration, maximize water purification according to local conditions, and create lakeside landscapes in combination with ecological governance.

生态敏感性Sensitivity to ecology
According to the surveys and analysis on the ecological sensitivity of the plot and its surroundings. The plot falls into the category of Caohai and the surrounding public green space, featured by wonderful natural environment. Based on the data from the local water department and the ecological protection section, the soil permeability is neutral, which can basically guarantee the recovery of groundwater. Besides, the vegetation diversity, and there are abundant varieties of wet plants, semi-moist plants, and terrestrial plants in the plot, which have formed the three-dimensional plant community. The slope of the terrain within the plot is between 5-15%. Surface water can be drained through natural infiltration, surface runoff, and organized artificial drainage without problems such as soil loss or soil erosion. Therefore, the ecological stability and adaptability in the region are really wonderful.

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 and all 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 pavements in 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.

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, the projects uses flowers, trees, waters and stones as landscaping materials and utilizes mountains, colorful clouds, and clear water 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.
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.People can listen to the flowing water and smell the taste of nature. In the few layers of scenery with water falls and winding paths, the clear sky is reflected on the clean water, producing the mist-like scenery.

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.
