Abstract：Intensive human activities have led to the changes in the landscape ecological health of Meizhou Island,revealing the landscape ecological health status and prediction of Meizhou Island,which provides the theoretical basis for the island environmental protection and ecological management and other work.Five periods of image data in 2010,2013,2016,2019,and 2022 were selected to construct the landscape ecological health evaluation system of Meizhou Island based on the PSR model,and the entropy value method and gray prediction model were applied to predict the health status of Meizhou Island in 2025,2028,and 2031.The results showed that over the past 12 years,the landscape ecological health of Meizhou Island had gradually decreased from the"healthy"level in 2010 to the"generally sick"level in 2022 due to the influence of anthropogenic factors,and the overall landscape ecological health is on a downward trend.It was predicted that the health level of Meizhou Island would be"generally sick"in 2025 and 2028,and"sick"in 2031.The ecological health of the landscape of Meizhou Island is under serious threat,and scientific protection and restoration measures are urgently needed to improve the island's management level.
