| 生物多样性是河流生态健康的免疫系统。恢复和提升城市河流生物多样性，让生命回归河流，是河流生态系统修复的主要目标和重要任务。以位于海口市秀英区的五源河为研究对象，在阐述河流修复前生态环境状况和生物多样性本底的基础上，论述五源河河流生态系统修复设计技术与实践，提出生态修复的4项策略：1）河道生态恢复——三维生态空间重建；2）河岸生态修复——柔性生态河岸设计；3）河流与湿地协同——河流–湿地复合体建设；4）多功能生境恢复——生命景观河流重建。基于生物多样性提升目标，从生命景观河流修复的角度，探索城市河流生态系统修复的创新路径和模式。最后，评估修复后五源河的生物多样性变化，结果表明：修复后的五源河河流生境类型多样，生境质量优良，生物多样性提升效果明显。生态修复实践表明，针对生物多样性提升的城市河流生态修复，更有利于城市河流生态系统整体保护及河流景观品质的优化提升。 |

| Abstract: |
| Biodiversity is the immune system of the ecological health of rivers. It is the main goal and important task of river ecosystem restoration to restore and enhance the biodiversity of urban rivers and return life to the river. On the basis of summarizing the ecological status and biodiversity baseline before the river restoration, this paper, using Wuyuan River in Xiuying District of Haikou City as a case study, discusses the design technology and practice of ecosystem restoration of Wuyuan River, and puts forward four strategies of ecosystem restoration: 1) ecological restoration of river course—three dimensional ecological space reconstruction; 2) ecological restoration of riverbank—design of flexible ecological riparian environments; 3) river and wetland synergy—construction of river-wetland complex; 4) multi-functional habitats restoration—reconstruction of life landscape rivers. With a view to biodiversity improvement, this paper explores the innovative path and mode of urban river ecosystem restoration from the perspective of restoration of life landscape rivers. Finally, the biodiversity changes of Wuyuan River after restoration were evaluated, and the results showed that the river habitat types were diverse, the habitat quality was good, and biodiversity was improved after restoration of Wuyuan River. The practice of restoration shows that river ecological restoration based on the biodiversity improvement is more conducive to the overall conservation of river ecosystem and the optimization of river landscape quality. |
