Abstract
Matlamat penyelidikan ini adalah untuk memeta ruang taburan tanah masin di lokasi yang berbeza di dataran Al-jafarah dan menentukan tahap kemasinan tanah dan membandingkannya dengan imej yang diperoleh daripada satelit landsat 7 ETM+. Sejumlah enam puluh (60) sampel dikumpul secara rawak daripada permukaan tanah pada kedalaman di antara 10-50 cm. dan diukur kandungan tanah selaras dengan Prosedur Piawaian Makmal Libya. Data kajian diperoleh daripada ujian makmal dan imej satelit landsat ETM+ 2010. Landsat 7 ETM+ (Enhanced thematic mapper plus) digunakan untuk memeta dan mencerap tanah masin di kawasan kajian. Keputusan yang diperoleh daripada makmal dan imej satelit apabila dibandingkan menunjukkan bahawa tanah masin hanya terdapat di kawasan paya.
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.
