inventaire sur les études pédologiques dans quelque régions du Sud-Est Algérien

Abstract

Ce travail consiste à faire un inventaire sur les études pédologiques dans la région Sud-Est algérienne (wilayats de Biskra, Laghouat, El-Oued, Ouargla, Ghardaïa et Illizi). A travers une recherche bibliographique, qui a touchée tous types de référence et une enquête réalisée dans plusieurs structures et établissements techniques et administratifs, nous avons recensé un nombre non négligeable des études pédologiques, dont 45 études académiques et 55 études téchniques, mais malgré ces chiffres la surface recouverte par ces études reste très petite par rapport à la surface totale -La majorité des études académiques sont des mémoires d’ingénieurs, elles ont été réalisées en grande partie dans les wilayats de Biskra et Ouargla. -La plus part des études techniques sont réalisées par le bureau de B.N.E.D.E.R. et l’agence de l’A.N.R.H, elles ont été réalisées en grande partie dans la wilaya de Biskra. -La majorité des études pédologiques sont de type morphologiques, analytiques et même des fois micromorphologiques surtout pour les études académiques. -Les études cartographiques présentent un pourcentage de 77,29 % par rapport à la surface totale étudiée Summary : This work consists in making an inventory on the pedological studies in the Algerian South-Eastern area (wilaya of Biskra, Laghouat, El-Oued, Ouargla, Ghardaïa and Illizi).
