| 摘要: |
| 在全球气候变化与快速城市化的双重驱动下，中国沿海地区面临海平面上升、生态退化与 灾害风险交织的多重挑战，传统海岸防护模式在适应性与生态协调方面的不足日益凸显。文章以上海为典型案例，构建了海岸带韧性综合评估模型（CRI），从工程、生态与社会 3 个维度，量化城市系统的适应能力与防护绩效。研究结果表明，上海在海岸韧性治理中表现出显著优势，CRI 综合得分达 0.80，属高韧性等级，其中生态修复与蓝碳固存贡献突出，工程防护体系稳固，而海平面上升与灾害影响下的风险暴露度偏高，灾害后社区及系统恢复速度偏慢仍为相对短板。敏感 性分析揭示了生态与社会因素对整体韧性的显著影响，亟须推进跨尺度风险统筹与生态工程适应 性优化。文章所提出的模型与路径可为中国沿海超大城市在全球变化背景下实现韧性转型提供科 学参考与决策依据。 |

| Abstract: |
| Amid global climate change and accelerated urbanization，China’s coastal regions face increasingly complex challenges from sea-level rise，ecological degradation，and compound disaster risks. Traditional coastal defense strategies exhibit limited adaptability and ecological coordination．A Coastal Resilience Index（CRI） framework is developed，incorporating engineering，ecological，and social dimensions to quantify the adaptive capacity and protection performance of coastal systems．The results show that Shanghai demonstrates high resilience with a CRI score of 0.80．Engineering protection is robust，and ecosystem services such as wetland restoration and blue carbon sequestration play a key role. However，elevated exposure to risks from high sea- level rise and disaster impacts，coupled with slow recovery rates of communities and systems following disasters， remain relative weaknesses．Sensitivity analysis reveals the significant influence of ecological and social factors on overall resilience，indicating the urgent need to promote cross-scale risk coordination and adaptive optimization of ecological engineering．The findings offer a replicable governance model and decision-making tool for coastal megacities seeking to enhance systemic resilience under global change. |
