Riverfront Landscape Based on the Idea of River Restoration: A Case Study of the Riverfront Landscape of Duoba New District in Xining City

With social progress and economic development, flood protection, water storage, and pollution absorption of urban rivers have been improved, but at the same time negative effects have been brought about. In urban areas, due to canalization or occupation of river, and forcible alteration of course of rivers, river waters area has been reduced. Natural capacity of rivers is seriously lacking, and the ecosystem services of rivers are gradually weakening. For planning, design and construction of urban landscapes, the concept of ecological restoration must be applied to protect and rationally utilize river landscapes. This paper takes the landscape belt of Huangshui River in Doba New City of Xining as an example to study the Huangshui River. Based on the theory of river course restoration, a “dynamic growth” river restoration system is established, and the restoration process of nature itself is as little as possible. In order to improve the water quality of Huangshui River, control the flow velocity and build the ecological environment, a set of perfect and self-repairing system is created for Huangshui River.
