The study of the soil biological environment is of great importance, because of the large variety of soil types in the dry subtropical and humid subtropical zones of Azerbaijan. The soil fauna participation in the soil formation process is always an urgent and priority subject. It plays an important role especially in bio diagnostic assessment of soils, organic substances conversion biological matters circulation and an energy circulations of the various parts in an ecological pyramid. The object of the study is natural cenoses, spread over the gray-brown soils of the Absheron Peninsula in the Kurdakhany lake surrounding areas and invertebrates living in these cenoses. On the gray-brown soils of the investigated territory, ephemeral-halophytic plants have largely spread. Studies were conducted in 2017-2018. In conducting field and laboratory studies to determine soil invertebrates, the Gilyarov’s method was used. The determination of plant species collected from the object of study was carried out according to the " Azerbaijan flora ". The taxonomy of the invertebrate animals in the soils under the ephemeral and halophytic vegetation formation in this zones has been fixed and the distribution analysis has been performed in the article. It was determined that the soil invertebrates concerning the Arthropoda type and insects class widely expand in the research zone.
