Abstract:
اعتمدت الدراسة تقنيتي الاستشعار عن بعد (R.S) ونظم المعلومات الجغرافية (GIS) في تمثيل مظاهر التصحر في محافظة البصرة على مدى الاربعين سنة الماضية (1973 - 2013)، ومحافظة البصرة من المحافظات العراقية ذات الاهمية الاستراتيجية، تقع جنوب العراق بين دائــرتـي عرض(2 | The study deals with the Remote Sensing techniques and Geographic Information System (GIS) in the representation of the manifistications of desertification in Basra province through the last forty years (1973 - 2013). of course , Basra province has an important strategic location amang other Iraqi province , for its situation is between latitudes (29? 6? 21? &31? 16? 45?) north and longitudes (46? 43? 33? &48? 37? 31?)to the east rond (17700 km2). As it includes wide plane lands and untapped often faced by a series of geographic factors which have led to desertification of the various forms of soil desertification. The study used sensors data (MSS , TM and LDCM) of the American Artificiat sat (Land Sat) , as well as using Sat data (Quick Bird 2 ) for three images Sattelite for the years (1973, 1990 and 2013) to determine the manifestications of desertification and the most important development which changes by analyzing the reflective properties spectral features floor of the study area visually and mechanically. The study relied an several indexs in the study and controlling aspects of desertification index (SI) for the study of soil salinity index (EMI) to measure wind erosion index (NDVI) for measuring the intensity of natural plant and other indexs cover , all of which show that the total desertified area in Basra province was (3156.2 km2) in 1973 it rose to (4714.6 km2) in 1990 and increases to (7803.3 km2) in 2013 to the appearance of salinity and wind erosion only sand and dunes. Matching Cartographic reveal the complex process (appropriate spatial) that natural factors played amajor role in increasing the desertified area Basra province suffers from desertification in general and particularly in Western divisions.
