The Alhagieto-Salsoletum-Artemisiosum fosmation group at the SiyazanNeft NQCI mine

Abstract

The species composition of the vegetation of the formation is richer than that of desert and semidesert phytocenoses; It was recorded in the vicinity of the 1208N well belonging to the 1N oil field of "SiyazanNeft" According to the relief, there is a corresponding grouping in depressions and hollows. There are 19 species in this phytocenosis, of which 2 species (10.5% shrubs, 1 species (5.3%) are semi-shrubs, 1 species (5.3%) are semi-shrubs, 7 species (36.8%) are perennial and 8 species (42.1%) are annual grasses. According to the ecological analysis, 5 species (26, 3%) mesophytes, 3 species (15.8%) of mesoxerophytes, 8 species (42.1%) of xerophytes and 3 species (15.8%) of halophytes. The abundance of the dominant vegetation Artemisia szowitsiana is 3-4 points, the abundance of subdominants Salsola dendroides is 2-3 points and the abundance of Alhagi pseudalhagi is 2 points. Oily soils where phytocenosis spreads are moderately polluted. The structure of the formation has three floors: Tamarix ramosissima, Lycium ruthenicum on the first floor; Artemisia szowitsiana, Salsola dendroides, Alhagi pseudalhagi, etc. are found on the II floor; Aeluropus littoralis, Lolium rigidum, etc. are found on the III floor. During the phytoecological studies, Polytrichum commune, which is typical of higher spores, is rarely found on the soil surface in the depression around the oil well No. 1208.
