These areas constituted a problem to geographers and statisticians who wished to assign them contours. The delimitation of peri-urban areas is indeed difficult and must combine geographic, urban, economic and human parameters that might render account of a movement that affects almost all areas. Our approach is a contribution to the use of simple and rapid decisions as a tool for the characterization of natural space in the suburban town of Sidi Bel Abbes. It is based on a diagnosis of the current situation in this municipality. The study allowed us to identify 106 natural areas in a suburban area of over 3969.36 hectares. Despite their spatial importance, these areas remain largely forgotten; It is therefore necessary to know their functions, developments and potential in order to keep the suburban biodiversity.
