Résumé

To estimate the overall air pollution in the Skikda region, the capital of petrochemicals in the north - eastern Algeria, we used a qualitative method based on the census and geographical distribution of the lichen flora corticolous according pink pollution of the study area networks combined with mapping. It is essential to know some biophysical factors such as climate and the tree flora (lichen substrate or phorophyte) to better understand their influence on the distribution of lichens in different stations. Thus, 39 lichen species have been identified in the 8 sites established as a zoning that takes into account their exposure to different sources of emanation. The census results of the lichen flora of the Skikda region and its periphery have shown clearly that the number and rate of recovery is closely linked to the degree of pollution. This finding is remarkable in the field by reducing the number of species and their recovery rate when the overall pollution is diffuse is important. Keywords: cartography - pollution - lichen - Skikda – Algeria.
