تأثير عامل تقوس التضاريس على التوزيع المكاني للنبات الطبيعي في منطقة أتروش باستخدام نظم المعلومات الجغرافية

Abstract EN

The study of caractestics of land form that representing in curvature digree and itis Effects on The plant cover, are very importance because itis join in natural Resourses development and development operation, in the dry area and sene –dry area with limit water Source, last years contain on, in formation technology development which helped in treatment and analysis surface of elevation in technical development method from the corporation between GIS and Remote Sensing which have high possibility to make information base to analysis digital elevation models and land sat to limitation The caracterstics of elevation and Land cover in area, in mechanical way and efficiency and quickly in achievement when comparative in Classical manual methods.

already done use Radarian Release (Hgl) special in north of Iraq picked up from u.s.

space Shuttle (NANSA) As main origin To datd which find out from it the information of curvature degree by using program Arc Gis v.9.3 in spatial Analysis Extension from window (Arc Toolbox) To ATROOSH area North East of Iraq while used spaces image (land sat7) in program Erdas to doning process of classification un guide to space data and extraction layer plant cover and then doing process of identify overly between curvature degree and layer of plant cover to show effect of curvature degree on density spatial existence to plant cover on new maps and new data base carry characteristic of two layers.
