Abstract

Abstract

This study aims to investigate the application of high-resolution remote sensing images in the supervision of river and lake sand mining in the Dongting Lake area. Based on the aerial and space high-resolution remote sensing images over the past 20 years, as well as human-computer interaction interpretation and field investigation verification, this study summarized the types and meanings of surface elements in river and lake sand mining, established the remote sensing interpretation symbols for river and lake sand mining, and analyzed representative typical cases. The results show that the interpretation symbols of remote sensing images for river and lake sand mining differ from those for onshore mining summarized previously. The river and lake sand mining was carried out using dredges as the mining equipment, sand carriers as the transport equipment, and sand yards and docks as transfer sites. The mining surfaces caused serrated bank lines during sandbar digging. Furthermore, surface cover changed near mining areas, including turbid water and shrinkage of sandbars and shoals. This study analyzed three typical cases, namely the evolution of the Hualong sand yard, the treatment of the Chenglingji wharf, and the illegal sand mining in Piaoweizhou of the eastern Dongting Lake. The analytical results indicate that high-resolution remote sensing can provide technical support for supervising river and lake sand mining.
