Short summary
This study used multi-source remote sensing data and ensemble learning methods to map the distribution of sandy beaches in China from 2016 to 2024. A total of 3447 sandy beaches were identified with high accuracy by integrating Sentinel-1/2 satellite imagery, terrain, and nighttime light data. Since 1990, the area at risk from human infrastructure squeeze has significantly increased. This study provides an updated dataset to support sustainable coastal management.
