Taking Changle Minjiang Estuary National Wetland Park as an example, the image data since 2008 were selected to construct the ecosystem health evaluation index system of Changle Minjiang Estuary National Wetland Park based on the PSR model. Combined with gray prediction model, the entropy weight method and comprehensive evaluation method were used to predict the health status of Minjiangkou National Wetland Park in 2020, 2022, and 2024. The results show that the landscape types between the salt marshes, meadows and water bodies in the Minjiang Estuary National Wetland Park repeatedly changed; The ecological health values in 2008, 2010, 2012, 2014, 2016, and 2018 were 0.740, 0.737, 0.740, 0.704, 0.640, 0.674, and 0.654, respectively, all were in a healthy state; Due to human disturbance, breeding density, urban and agricultural factors, the overall trend was decreasing, and the predicted ecosystem health values are all sub-health in 2020, 2022, 2024.
