| 海岸防护工程对防止海岸带侵蚀,维持生态系统完整性和多样性至关重要。传统硬质海堤较少考虑其对海岸带生态环境的影响。随着中国进入生态环境高质量发展新阶段,对海岸防护工程的生态效应方面提出了更高的要求。目前,对已建成的硬质海堤进行生态化改造,或在充分考虑自然条件和防护性能的基础上建设具有保护与维持海岸带生态环境的生态海岸防护工程已是大势所趋。生态海岸防护工程的宗旨是尽可能地维持当地海岸带的自然生态环境,同时通过削减波浪能量保护海岸带侵蚀。目前关于生态海岸防护工程主要集中在理论和理念方面,在具体的实施和建设环节,仍存在建设标准不完善、建设成本过高、缺乏系统持续的监测数据以及生态效应评估不足等问题。因此,后续应进一步完善我国生态海岸防护工程技术体系,加强生态海岸防护工程关键技术研发,建立持续的系统的环境生态监测体系,并对生态海岸防护工程生态效益进行持续关注和评价。 |

| Abstract: |
| Coastal protection infrastructure plays a pivotal role in preventing erosion and protecting the integrity and diversity of the coastal ecosystem. Construction of traditional hard seawalls often neglects the influence on the coastal ecological environment. As China enters a new stage of high-quality development of ecological environment, the ecological efforts of the coastal protection infrastructure are required. At present, ecological enhancement of existing traditional hard seawalls and new construction of ecological infrastructure become a trend of development. Coastal ecological infrastructure could maintain the natural coastal ecological environment, and protect coastal ecosystem via reducing wave energy. Many theoretical studies of coastal ecological infrastructure have been reported. However, in China, concrete issues of imperfect construction standards, high costs, lack of systematic monitoring data, and subsequent evaluation of ecological restoration remain to be solved. Therefore, the engineering technology system of coastal ecological infrastructure suitable for China-specific conditions should be improved, the research of key technologies for coastal ecological infrastructure should be enhanced, a long-term on-site ecological monitoring mechanism should be established, and the long-term influence of the coastal ecological infrastructure should be concerned and evaluated. |
