Abstract：Based on the actual situation of coastline advancement and retreat in typical coastal areas of Hebei Province，this study systematically investigated the relationship between coastline dynamic changes and the distribution patterns of fishery resources. By utilizing remote sensing to extract coastline evolution data，spatio一temporal surveys of fishery resources，and statistical analysis methods， the study elucidated the mechanisms through which coastline changes influence the area of fishery habitats，the structure of resource communities，and the efficiency of unit output.The research findings indicate that shoreline changes have led to a reduction in dominant benthic species，spatial displacement of resource core zones，and decreased productivity，reflecting typical trends in ecosystem restructuring. Combining changes in indicators such as habitat compression and increased community heterogeneity，the study proposes the establishment of a responsive resource management model based on dynamic shoreline monitoring.
