Abstract. The article is dedicated the ways of researching in soil salinity evaluation of the Kur-Araz lowlands with the Remote Sensing (RS) techniques and applying va­rious vegetal indices for decision salinity degree. The research results show that there are some advantages of the RS-based research in comparison with the traditional methods of determining the soil salinization. The pro­perties of the halophytic plants, which reflect salt cha­racters in the salinized soils, have been used in the RS data-based research process. The halophytic plants have been used as a parameter for study of the salinity state with the Remote Sensing data. These parameters have been obtained by the processing of the multispectral images got from Landsat-7 satellites, using mathema­tical methods.
