The potential of self-purification and the resistance of soils and the main cadastral areas of Azerbaijan on the example of pollution with substances of organic nature-petroleum hydrocarbons, using the proposed formula of the soil-bioecological index, were evaluated using the methods of systematic conjugate analysis of abiogenic and biogenic factors. The regularity of increasing the intensity of decomposition of pollutants when moving from the East to the West on the territory of the country is shown. In the opposite direction, the potential risk of accumulation of pollutants in soils is increasing due to a decrease in soil resistance to pollution. The soil resistance to pollution in cadastral areas is not the same in comparison. Guba-Khachmaz, Lankaran-Astara, Kalbajar-Gubadli, etc. cadastral areas in general are characterized by a relatively high current stability and self-cleaning ability compared to the Absheron region and the territory of the Nakhchivan Autonomous Republic. The potential for self-cleaning of the territory of Azerbaijan as a whole is quite high – about 87 % of its territory is sufficiently resistant to pollution. The proposed approach makes it possible to develop zoning maps of the territory of Azerbaijan based on the nature of potential changes in natural landscapes when they are polluted and timely plan the measures for their restoration. The positive correlation between the assessment scores and soil microbiological indicators shows that ecological scales can be used for preliminary zoning of Azerbaijan landscapes, including the soil cover, according to their self-cleaning potential. As a first approximation, the cartogram of soil bonitet in Azerbaijan can be used to develop cartograms of soil stability indicators in relation to pollutants of various nature.
