Abstract
Biodiversity is the immune system of river ecological health. Restoration and improvement of urban river biodiversity and the return of life to rivers are the main goals and important tasks of river ecosystem restoration. Taking the Wuyuan River located in Xiuying District, Haikou City, as the research object, based on the ecological environment and biodiversity background before river restoration, the design technology and practice of Wuyuan River ecosystem restoration were discussed, and four strategies of ecological restoration were put forward: 1) River ecological restoration—three-dimensional ecological space reconstruction. 2) Riparian ecological restoration—flexible ecological riparian design. 3) River-wetland synergy—River-wetland complex construction. 4) Multi-functional habitat restoration—life landscape river reconstruction. Based on the goal of biodiversity improvement, the innovative path and mode of urban river ecosystem restoration were explored from the perspective of life-landscape river restoration. Finally, the biodiversity of the Wuyuan River after restoration was evaluated. The results showed that the habitat types of the Wuyuan River after restoration were diverse, the habitat quality was good, and the improvement effect of biodiversity was obvious. The practice of ecological restoration shows that urban river ecological restoration aimed at the improvement of biodiversity is more conducive to the overall protection of urban river ecosystems and the optimization and improvement of river landscape quality.
