摘要

The objective of the study is the identification and mapping of zones Alfa at the level of wilaya of Saida. and this through a methodology which combines both between phytoecological diagnosis (sampling techniques) and tools of GIS Geographic Information Systems, to create a georeferenced database on the Alfa. This enables to characterize the ecosystem of Alfa in its environment (climate, flora and soil). The study identified 13 plant groups corresponding to the steppe to Alfa. The synthesis of different historical cartographic data associated with field studies and applications related to the G.I.S has developed a geographic distribution map of the Stipa tenacissima and also to establish a map of proposed actions for a better management of this ecosystem in the study area. Two types of ecosystems can be distinguished: mixed ecosystem to Alfa in Northern and ecosystem to Alfa in Southern.
