Abstract
The particulate air pollution may be natural or anthropogenic, with different shapes and diameters of particles. What allow them to reach the lung and the blood increasing not only respiratory and cardiovascular disease but also the risk of mortality. To eliminate the particulate air pollution in a city such as Meknes, the study of the air pollution distribution in the urban area seems necessary. And as the mapping is the most suitable way for a good spatial representation, we had used geostatistics, which permits the characterization of the spatial variability of any property and, its estimate turns out to be very appropriate to map the phenomenon of dispersion. The maps obtained from of two interpolation methods, the deterministic method: IDW (Inverse distance weighting) and the geostatistical technique: Kriging, show that all districts of the Meknes city suffer from a large dust with different degrees, and that particulate air pollution in Meknes is not limited to the border area of pollution sources but it is characterized by the invasion of other areas (action of prevailing winds).

Abstract: (french)
La pollution de l'air par les particules peut être d'origine naturelle ou anthropogénique, ces particules sont de types et diamètres différents. Ce qui leur permet d'atteindre les alvéoles pulmonaires puis le sang, en provoquant non seulement de maladies respiratoires et cardio-vasculaires, mais elles peuvent aussi augmenter le risque de mortalité. Afin de lutter contre la pollution atmosphérique due aux particules dans une ville comme Meknès, une étude sur la distribution de cette pollution semble nécessaire. Et, comme la cartographie constitue le moyen le plus adapté pour une bonne représentation spatiale, nous avons fait appel aux outils de la géostatistique pour cartographier ce phénomène de dispersion. Les cartes obtenues suite à l'utilisation de deux méthodes d'interpolation: La méthode déterministe : IDW (Pondération par l'inverse de la distance) et La technique géostatistique : Krigeage, montrent que tous les quartiers de la ville de Meknès souffrent d'un empoussièrement important avec des degrés différents, et que la pollution atmosphérique particulaire à Meknès ne touche pas seulement la zone limitrophe des sources de pollution mais elle est caractérisée par l'envahissement des autres zones (action des vents dominants).
Author Keywords: Pollution particulaire, SIG, interpolation, IDW, Krigeage.
