| 摘 要： | 全球气候变化背景下,海平面上升以及高潮位和风暴潮引起的极值水位导致的海岸洪水对沿海社会经济和自然环境造成巨大影响,已是国内外关注的重点。论文梳理了广义和狭义海岸洪水的定义和要素,重点阐述了狭义海岸洪水的组成部分,从致灾因子、孕灾环境和承灾体以及风险评估方法与模型3个方面,系统总结了相关研究方法与研究成果的主要进展,以及存在的主要问题,并透视了未来拟加强的研究方向。建议加强沿海地区应对全球气候变化风险的研究,包括全球气候变化下多致灾因子耦合危险性和不确定性研究,沿海关键地区和关键暴露(关键基础设施)的风险评估研究,全球气候变化风险适应与减缓性措施的成本效益评价研究,提高沿海地区应对全球气候变化风险的韧性研究,以及建立多学科间的基础数据共享机制,采用交叉学科手段以便更综合、系统、动态研究海岸带问题,保障沿海地区开展全球气候变化下风险评估的需要。 |

| Abstract: | The sea level rise under global climate change and coastal floods caused by extreme sea levels due to the high tide levels and storm surges have huge impacts on coastal society, economy, and natural environment. It has drawn great attention from global scientific researchers. This study examines the definitions and elements of coastal flooding in the general and narrow senses, and mainly focuses on the components of coastal flooding in the narrow sense. Based on the natural disaster system theory, the review systematically summarizes the progress of coastal flood research in China, then discusses existing problems in present studies and future research directions with regard to this issue. It is proposed that future studies need to strengthen research on adapting to climate change in coastal areas, including studies on the risk of multi-hazards and uncertainties of hazard impacts under climate change, risk assessment of key exposure (critical infrastructure) in coastal hotspots, and cost-benefit analysis of adaptation and mitigation measures in coastal areas. Efforts to improve the resilience of coastal areas under climate change should be given more attention. The research community also should establish the mechanism of data sharing among disciplines to meet the needs of future risk assessments, so that coastal issues can be more comprehensively, systematically, and dynamically studied. |
