Abstract

The land cover type and river morphology changes are closely related and will have a profound impact on human life and ecosystems. This article is based on the 2-meter resolution ZY-3 satellite images to carry out land cover and river geomorphology monitoring in the typical demonstration area of the Ping River in Thailand. The results showed that the classification accuracy of land cover in 2013 and 2019 was 95.78% and 92.71%, respectively. The surface type with the greatest change was bare land, which decreased from 1352.33 km2 to 593.08 km2. The curve shape of the Ping River in the demonstration area has undergone significant changes, posing a high risk of erosion and sedimentation, especially in cultivated and bare land areas.
