Project Introduction:

The first phase of the Yangtze River Bank Wetland Protection and environmental Improvement Project in Jiangbei New Area covers Dingshan Street - Zhujiashan River, and is implemented by Jiangbei New Area Public Construction Center. The project is about 5.6 kilometers long, including Yangtze River bank safety restoration project, environmental and ecological protection project and environmental and ecological improvement project. By demolishing some old buildings, docks, houses and other facilities along the line, It has solved the problem that the Yangtze River bank is not connected for many years. The project started construction in November 2019 and will be completed and opened to the public in May 2021. The project construction puts ecological protection and green development in the first place, people-oriented, with "Yangtze River protection" as the core, landscape environment improvement as the starting point, ecological security, shoreline protection, ecological restoration as the strategy, and vigorously improve the ecological environment along the river in Jiangbei New Area.

Construction concept:

The project responds to the top-level design of the "Great Protection of the Yangtze River", takes protection as the background, restructures the "riverside, near the river and see the river" landscape corridor, integrates leisure functions, promotes industrial renewal, carries forward regional culture, and highlights the sense of belonging and pride in the development of the new district. The construction goal is to build Jiangbei Riverside into the world's most beautiful urban riverside ecological waterfront, and realize the beautiful vision of "the most beautiful waterfront, the nearest future". The construction of this project is in line with the main goals of the construction of "beautiful and livable city" in Jiangsu Province, that is, emphasizing respect for nature and adapting to nature, defining urban development boundaries with "mountains, rivers, forests, fields, lakes and grasses" as the base, and organically connecting urban public space with garden green space system, truly integrating nature into the city and letting people see the water.

Empirical practice:
1. Ecological and landscape treatment of flood control facilities:
On the one hand, the original flood control wall along the coastline should be removed, and the design method of combining embankment should be adopted to build ecological flood control levees on the basis of ensuring residents' proximity to and proximity to the river. On the other hand, the effect of the original hard slope protection landscape was poor, so the project carried out ecological transformation of the hard slope protection on the basis of ensuring the safety of water conservancy and flood control. According to the design water level height, the bank slope treatment method of "Reynold stone cushion slope + pebble beach + landscape walk + grass planting slope" was innovatively proposed, which simultaneously met the safety, landscape ecology and service functions of the bank slope.

2. Selection of plant species adapted to water level elevation:
Suitable plant resources were selected according to different water level elevation and inundation duration. At the same time, the planting time and maintenance period of plants adapted to the change of water level were summarized.
3. Diversified utilization of riverside waterfront:
According to the slope ratio and stability of the shoreline, different landscape shoreline is set up according to different landscape zones to create a rich experience space, such as sand beach, pebble beach, ecological beach, and falling hydrophilic platform.

4. Protection and utilization of current plants:
At present, there are a large number of trees that have been baptized by the flood, such as willow, maple, poplar, etc. The landscape makes creative use of them, and gives the plants new vitality and vitality through pruning, reshaping and rejuvenating measures.


Innovation highlights:
1. Culture with Song of the Yangtze River as its theme:
It shows the unique position of Nanjing in the Yangtze River civilization, interprets the Yangtze River civilization through landscape sculpture, landscape wall, ground carving and other elements, and shows the ecological characteristics.

2. Fully explore ecology:
From Renault pads to provide a good base for plant growth, to the ecological transformation of hard slope protection. From the use of sponge city to the selection of native plants, the ecological concept is demonstrated, reflecting the spirit of Yangtze River protection.
3. Adhere to the principle of ecological priority and harmony between human and water, and build a recreational waterfront waterfront with water ecological civilization:
In the design, the project makes use of the wide river beach and embankment along the river, combines the construction of municipal roads, includes leisure parks, bicycle walking systems, riverside squares, children's leisure parks, etc., and combines the single city flood control project with the construction of urban roads, urban landscape construction, riverside tourism and leisure and other infrastructure construction. Build a riverfront service economic belt, landscape belt and cultural belt with modern public facilities as the core content, and become a model of riverfront project with human-water-city harmony.
