| 海洋为人类生存和社会经济发展提供了重要的资源和环境条件，海洋生态适宜性研究能够评定海域的固有属性对生态保护和开发利用的适宜等级和潜力限制因素.本研究以典型的海岛区洞头为例，构建了海洋生态适宜性评价的空间分析模型，计算得到其空间分布，进而开展了生态适宜度的功能分区；据此划分了洞头区的生态管控空间，判断了未来海域资源保护和开发利用管理的主导方向，提出了各管控区发展的资源优势及限制性因素.结果表明，洞头海域按照生态适宜度值的高低可以清晰地划分为重点保护区、一般保护区、适度开发区和优化开发区等4类功能区，分别占区域总面积的23%、50%、18%和9%；前两者为生态保护及恢复的重要区域，后两者是未来海洋资源开发利用的主要区域；4类区域可以归并为生态保护、农渔业养殖、城镇开发3类管控功能区.本研究对开展海洋生态功能区划、协调海洋资源开发与区域生态保护的关系、构建基于生态系统的海洋综合管理模式具有重要意义. |

| Abstract: |
| The role of marine ecosystems, as critical elements of global life support systems, has gradually become recognized. Ecological suitability analysis can reflect the advantages of regional marine resources and the potential socio-economic development. In this study, taking an example of the island district, Dongtou, we constructed a comprehensive evaluation model in order to designate the main function areas of the ecological suitability. Then the predominating direction of regional marine resources protection and utilization was recognized and the advantages and limitations of each function area were illustrated. The results indicate that marine resources utilization can be clearly divided into four categories in the study area. They were key protected zones, general protected zones, moderately developed zones and optimized developed zones where they occupies 23%, 50%, 18% and 9% of the whole region, respectively. The first two zones are sensitive to the environment and thus are considered to be the important ecological restoration areas of the county, while the latter two zones are buffer areas for future marine resources utilization. Refers to the marine functional zone, three development modes of urban exploitation, fishery farming and ecological protection could be recognized for further marine resources management. This study has significant implications for marine ecological functional zoning, resolution of conflicts between the marine resources conservation and exploitation as well as the construction of a comprehensive regional marine management pattern. |
