Abstract
Saline soil is one of the popular soil degradation progress, which happens in areas where evapo-ration is higher than rainfall or coastal areas. Saline soil is determined by total dissolved sanity (TSMT). This paper proposes defining TSMT, for whole Uong Bi city, based on the regression equa-tion. The paper uses the bands and index images of Landsat 8 OLI data and field sampled TSMTs to find out the correlation between them and the regression express. The paper results show the abili-ty to use remote sensing image for mapping saline soil. This paper is a product of the project (coded BDKH.10/16-20) “Researching and applying modern technologies for building natural resource change management models, completing the management tools, and improving the monitoring capacity in land use change.”
