| 为系统推进海岸带生态修复和实现海岸带可持续发展，文章以象山港流域为例，基于国土空间重塑理论和景观生态理论，在陆海统筹视角下构建“本底评估-风险诊断-格局构建-分区修复”的海岸带生态修复分区技术框架，并进行生态修复分区。研究结果表明：象山港流域的生态重要性整体较高，其中林地水体生态系统是核心，约有50%为生态极敏感区域和生态高度敏感区域；12个生态源地通过生态廊道相互连接，呈现“两横一纵”的总体生态安全格局；结合生态安全格局构建、生态重要性和生态敏感性分析以及海洋功能区划，象山港流域可划分为2个等级生态源点、3条生态带、1个恢复区、3个缓冲区、3个保育区和5个修复区，分别开展相关生态修复工程。 |

| Abstract: |
| In order to systematically promote the ecological restoration and realize the sustainable development of the coastal zone, this paper took Xiangshan Port basin as an example, based on the theory of land space reconstruction and landscape ecology, from the perspective of land and sea coordination, built a zoning technical framework for coastal zone ecological restoration of “background assessment-risk diagnosis-pattern construction-zoning restoration”, and carried out ecological restoration zoning. The results showed that on the whole, the ecological importance of Xiangshan Port basin was very high. Among them, forest and water ecosystems were the core. The 12 ecological sources connected each other through the ecological corridors, presenting the overall ecological security pattern of “two horizontal and one vertical”. Combined with the construction of ecological security pattern, analysis of ecological importance and ecological sensitivity and marine functional zoning, Xiangshan Port basin could be divided into 2 hierarchical ecological source points, 3 ecological belts, 1 restoration area, 3 buffer areas, 3 conservation areas and 5 restoration areas, and relevant ecological restoration projects could be carried out respectively. |
