| 摘要: |
| 在全球气候变化和人类活动的双重胁迫下，人口密度高、经济发达的沿海地带成为生态环境风险的高危地区。为揭示研究区海岸带韧性特性，有效评价海岸带韧性发展历程，从而对海岸带韧性提升提出针对性成效管理策略。本研究以闽南沿海地区的18个县区（不包括金门县）为研究对象，选取海岸动力、海岸防护能力、经济发展、社会发展以及生态特征等5个方面、14个海岸韧性指标因子，利用AHPCritic法、灰色关联TOPSIS法、自然断点法以及贡献度模型，构建研究区海岸带韧性评价体系。结果表明，闽南沿海地区在空间上呈现出中部以厦门市辖区为代表区域的海岸带韧性高值区（韧性平均值为0.517~0.542），南部是漳州沿海地区的海岸带韧性低值区（韧性平均值为0.482~0.514）；海岸动力、海岸防护能力是其主控要素和影响因子。闽南沿海地区韧性演化经历了3个阶段，分别是早期的韧性提升阶段（1980—1990年），经济高速发展中生态环境造破坏的韧性破坏阶段（1991—2010年），注重生态修复保护工作，使海岸带韧性提升的恢复阶段（2011—2020年）。厦门、漳州、泉州三地在上述3阶段的韧性演化过程存在时间上的相位差异，其与三地不同的区位特点与地域经济发展历程有关。 |

| Abstract: |
| Under the dual coercion of global climate change and human activities, the populated coastal zone of highly developed economy has become a highrisk area treated by ecological and environmental risks. In order to reveal the characteristics of coastal zone resilience in the study area and effectively evaluate the development history of coastal zone resilience, so as to propose targeted effectiveness management strategies for coastal zone resilience enhancement. Thus，14 coastal resilience index factors of 5 aspects, including coastal dynamics, coastal protection capacity, economic development, social development and ecological characteristics of 18 counties in the coastal area of southern Fujian are selected for this study. At the same time, the AHP-Critic method, the grey correlation TOPSIS method, the natural breakpoint method and the contribution model were used to construct a coastal zone resilience evaluation system. Results show that the central area of coastal zone in southern Fujian shows a high value of coastal zone resilience presented particularly by Xiamen counties where the value ranges from 0.517 to 0.542, and lower value is located in the southern Zhangzhou ranged from 0.482 to 0.514. It is believed that the coastal dynamics and coastal protection capacity are the main factors controlling and influencing the resilience resilienoy. The evolution of coastal zone resilience in southern Fujian has gone through three stages, namely the early stage in 1980-1990, the middle stage in 1991-2010 when the ecological environment was harmed due to rapid economic development and the recovery stage in 2011-2020 when ecological restoration and protection work was carried out. In all, there were three different temporal phase identified in the evolution of coastal resilience in Xiamen, Zhangzhou and Quanzhou characterized by different regional features and the historical economic development. |
