EVOLUTION DE L'OCCUPATION-UTILISATION DU SOL EN CONTEXTE AGRICOLE INTENSIF : ESSAI DE SIMULATION DE LA COUVERTURE HIVERNALE DES SOLS DANS LE PERIMETRE IRRIGUE DE KALAAT LANDALOUS (NORD-EST TUNISIE)

Abstract : The objective of this study is to develop a reproducible method that allows for a short-term prediction (5 years) of the winter cover of soils in the irrigated perimeter of Kalaât Landalous (idea inspired by the work of CORGNE S., 2004). Indeed, this type of coverage has a proven impact on water quality. It affects the transfer of pollutant flows from agriculture in the irrigated areas. His prediction, can be an aid to programming of actions in projects to restore the water quality. However, it raises a number of methodological problems. Approximate approach which is based on an expert model and uses the rule of the Dempster-Shafer evidence was chosen because it allows to take into account the vagueness and gaps in knowledge related to the problem and available data, and involve a degree of confidence in the results produced. Predictions of winter cover soil are carried out according to two hypotheses "Soils covered" and "bare soil covered by little." After determining the spatiotemporal dynamics of past changes, especially from a series of multi-temporal remote sensing images, and have defined the factors motivating the changes past and future, the fusion of information sources that are these factors will be conducted with the rule of Dempster-Shafer (CORGNE S., 2004).
