Аннотация:For balanced approach to Sustainable Development Goals,the physical and chemical degradation of soils in result of oil pollution were studied.The data on the particle-size distribution and the content of chemical cjmpoments in the soil of the Tamtsagbulag and Zuunbayan oil-producing areas are presented.Due to arid and could climate and geographical location of inland and mid-latitude highlands the studied soils are characterized by similar physical and chemical properties:high content of physical sand(particle size >0.01 mm) up to 86-91%,alkaline reaction pH up to 8,7-8,8, density of the solid phase 2.63-2.64g/cm3. However, the total carbon content is much higher in Tamtsagbulag soils (kastanozem soils of dry steppe zone) than in Zuunbayan soils(semi-desert brown soils0 -1,07 and 0,24% respectively.The content of petroleum hydrocarbons (HC) in the Zuunbayan soils varies from 9 to 60 mg/kg, in the Tansagbulag soils- from 7 to 670 mg /kg with a maximum in the vicinity of the operating wells.According to the level of hydrocarbon pollution, Zuunbayan soils can be attributed to uncontaminated(" background" of HC up to "moderate level" of pollution (locally, near the well).Despite the locality and "moderate level" of oil pollution of Tamsagbulag soils, a study conducted using remote sensing, methods showed that pollution has a certain effect on vegetation cover. The maximum vegetation index value is some but reliably lower in an oilfield ( within a radius of 4 km) than adjacent territory.For sustainable solutions planning of the oil production , transportation, fnd pollution prevention the transcendental Biogeosystem Technique methodology will be helpful for Land Degradation Neutrality implementation.
