Health assessment of marine ecosystems serves as a crucial safeguard for implementing integrated land-sea management and supporting the sustainable development of coastal economies.Research on suitable re-gions for ecosystem health assessment has often treated water bodies as homogeneous,giving insufficient consider-ation to the environmental differences between various types of water bodies,such as estuaries and bays.Conse-quently,estimating the impact of spatial heterogeneity on the results of ecosystem health assessment is difficult.Therefore,it is urgent to establish a reasonable zoning method.Based on a review of domestic and foreign literature and relevant documents,this paper reviews the research progress of marine ecological zoning methods at home and abroad.Thereafter,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 proposed for different types of water bodies.This study provides new ideas for the refined management of the health of coastal ecosystems.
