The ecological environment of coastal wetlands is a vital foundation for maintaining regional ecological security and biodiversity, as well as for achieving sustainable economic and social development. However, rapid economic growth has led to increasing human disturbance to wetlands. In particular, while tourism promotes local economic development, it also brings a series of ecological and environmental problems that seriously constrain the sustainable development of coastal areas. Therefore, exploring the spatiotemporal variation of coastal wetland ecological environment and the spatial effects of tourism is of great significance for promoting sustainable wetland development. This study takes the Yellow River Delta coastal wetland as the research area. Based on Remote Sensing data from 2009 to 2024, it constructs an ecosystem quality index and conducts spatial analysis through the Geographic Information System. The Spatial Dubin Model and spatial effect decomposition method are used to empirically examine the impact of tourism on ecosystem quality. The findings indicate that the ecosystem quality of the Yellow River Delta wetland exhibited an overall upward trajectory with minor fluctuations throughout the study period. Regions classified as excellent and good expanded in a Y-shaped pattern, showing a significant positive spatial autocorrelation. The direct and indirect effects account for 69.1% and 30.9% of the total effect, respectively. This indicates that local tourism development not only damages the local ecosystem but also exerts negative effects on surrounding areas. These findings suggest that ecological governance should shift from administrative divisions to regional coordination, and establishing a horizontal ecological compensation mechanism is essential for achieving coordinated development.
