摘要: 三峡库区生态环境是长江生态大保护的关键，消落带恢复治理是重中之重。在三峡库区消落带恢复治理中，重庆主城区长江 段面临着极其严酷的环境胁迫。以重庆主城区九龙外滩的滨江消落带为例，运用界面生态调控技术、立体生态空间建设技术 和滨江消落带韧性景观修复技术，在前期规划设计的基础上，开展了九龙外滩340 m长的滨江消落带的生态景观修复示范研 究，成功筛选出耐淹性强的植物种类。阶段性试验研究的结果表明，这些植物面临持续不断的洪水冲刷淹没及高温干旱交替 的逆境，无论是植物种类，还是植被结构方面，都表现出了良好的韧性适应。通过运用适应水位变化的滨江立体生态空间建设 技术，试验段滨江立体生态空间格局初步呈现，与周边的裸滩形成鲜明对比，生物多样性丰富，生态服务功能持续优化。

Abstract: The ecological environment of the Three Gorges Reservoir Area is the key to the great ecological protection of the Yangtze River, and the restoration of the littoral zone is the most important. In the Three Gorges Reservoir Area, the Yangtze River section of Chongqing's main urban area is facing severe environmental stress. Taking the riverside and littoral zone of Jiulongwaitan in Chongqing as an example, this paper uses the technology of interface ecological regulation, three-dimensional ecological space construction and the technology of resilient landscape restoration for riverside and littoral zone. A demonstration study on the ecological restoration and landscape optimization of riverside and littoral zone with a length of 340 m was carried out. The results show that the plants with strong submergence tolerance were successfully screened, and both plant species and vegetation structure showed good resilience and adaptability. The spatial pattern of the three-dimensional ecological environment along the riverfront in the experimental section is preliminarily presented. In contrast to the surrounding bare beach, it has abundant biodiversity and continuous optimization of ecological service.
