Abstract. The climate of the area is dry subtropical, the natural vegetation is drought-resistant,
heat-resistant and less demanding on soil.In accordance with these climatic conditions, plants
have acquired a number of adaptations.Usually, xerophytic plants predominate, and in these soils,
drought plant species with a strong root system, thorny, resistant to harsh winds, adapted to saline
soils and sunny weather, are better developed. Mainly annual, perennial herba-ceous plants and
shrubs are found. They have a number of adaptations against water loss (their leaves are hairy or
limp, etc.) there is. Among annual grasses, ephemeroids predominate, and in perennials-ephemeroids.
In modern times, in the territory of Azerbaijan, vegetation is subject to decline or degradation
in man-made disturbed, including oil-polluted lands. So, here it is required to prevent anthropogenic
and man-made effects, as well as based on the classification of phytoce-noses for the purpose
of biological recultivation.
We conducted phytoecological studies and identified 16 formation classes, 19 formation
groups, and 26 associations in 5 vegetation types. Based on our analysis of the phytoecological descriptions
recorded during field studies, we classified the selected oil-contaminated vegetation on
the country’s territory according to the “objects of the study.” In 9 exemplary objects, we found the
same number of formation groups related to the types of halophyte deserts, psammophyte deserts,
semi-deserts, thickets, and wetlands in the vegetation classification. So, the appropriate classification
was given by us for the first time.
