Abstract

The salinity characteristics and spectral characteristics of salt-affected soil constitute the basic research

contents in hyperspectral remote sensing quantitative monitoring of saline soil. The Caka-Gonghe basin is situated in the

eastern margin of the Qaidam Basin, where the soil salinization is typical. Based on the physical and chemical analysis of

the soil and laboratory spectra of the samples, this paper discusses the salinity characteristics and spectral

characteristics of the samples and analyzes the regularity of the variation of the spectral characteristics with the

salinity characteristics. Studies have shown that chloride saline soil is dominant in the study area, and that the spectral

characteristics show marked differences due to the different salinities in the saline soil.
