| dc.description.abstract | The aim of this research is to map the spatial of the distribution of saline soils in the different locations in the Al-jafarah plain and to determine the level of salinity in the soil and compare against the satellite images landsat 7 ETM+. Sixty samples were collected randomly from the 10-50 cm surface soil layer and measured for salt content in accordance with Libyan laboratory standard procedures. Data collected for this study involves laboratory testing and satellite images landsat ETM+ 2010. Landsat 7 Enhanced thematic mapper plus (ETM+) was used to map and observe saline soil in the study area. The results derived from the laboratory and satellite images, when compared against each other, have found that the saline soil is present in marshes, none in other areas. The results showed that the sand areas were expanded over Al-jafarah plain. It can also be observed from classified images that the salty lands (Sebkha) spread in northwestern Al- jafarah Plain limited between the longitudes of 11°30´ , 12° 30´, and latitudes 32° 30´, 33° 30´ in the western area of the study area, because the rate of salinity in the study areas is less than 2 dS/m (non saline), alongside existence of high spectral reflectance response of dry and sedimentary soils (non saline), it is around (120-230 DN value). | en_US |
