This study was based on Quaternary geological remote sensing survey of the main stream basin (Yanyuan Basin) in

Sichuan. Through remote sensing investigation and analysis of resources and research on Quaternary residual and slope

sediments, the authors set up image features of remote sensing recognition of Quaternary residual and slope sediments and

got to know the distribution characteristics of Quaternary residual and slope sediments. According to soil structure, rock

property and geological background characteristics of Quaternary residual and slope sediments, the authors hold that, as

land has become increasingly less in China, the development of remote sensing investigation of Quaternary residual and

slope sediments has great significance in that its can find and explore new potential areas of land resources.
