| 摘要: |
| 海洋生态系统健康评价是开展陆海统筹管理、支撑沿海经济可持续发展的一项重要保障。针对生态系统健康评价区域，在前期研究中往往作为同类水体进行考虑，对河口、海湾等不同类型水体的环境差异考量较少，难以体现空间异质性对生态系统健康评价结果的影响，亟待建立合理的分区方法。基于国内外文献及相关文件，综述国内外海洋生态分区方法的研究进展，在此基础上，借鉴欧盟水框架指令水体分类思想，针对河口、海湾等不同环境类型水体，初步提出了一套耦合关键分区因子N和其它因子X的海洋生态系统健康评价分区模式，为近海生态系统健康的精细化管理提供新思路。 |

| Abstract: |
| The health assessment of marine ecosystems serves as a crucial safeguard for implementing integrated land - sea management and supporting the sustainable development of coastal economies. In previous studies on the regions for ecosystem health assessment, the water bodies were often treated as homogeneous. Insufficient consideration was given to the environmental differences among various types of water bodies such as estuaries and bays. As a result, it is difficult to reflect the impact of spatial heterogeneity on the results of ecosystem health assessment. Therefore, it is urgent to establish a reasonable zoning method. Based on domestic and foreign literature and relevant documents, this paper reviews the research progress of marine ecological zoning methods at home and abroad. On this basis, drawing on the concept of water body classification in the EU Water Framework Directive, a zoning model for marine ecosystem health assessment that couples the key zoning factor N and other factors X is initially proposed for different environmental types of water bodies such as estuaries and bays. The new ideas for the refined management of the health of coastal ecosystems. |
