Abstract: Balti urban ecosystem, is located in the Steppe Plain of the Lower Cubolta, which is part of the Steppe Balti District (VII). Previous studies indicate that it,s flora obviously differs from the typical spontaneous zonal flora of the steppes. In Balti urban ecosystem, research was conducted in 13 stations during the vegetation period using the linear transect method. The purpose of the research was to assess biocenosis indices, such as the frequency and constancy of herbaceous plant species, in order to determine which species have greater plasticity and capacity to adapt to the conditions of the urboecosystem. Species frequency represents the ratio, between the number of sites where the species is recorded and the total number of sites analyzed. To assess the frequency of the species, there were sufficient qualitative data on its presence or absence in the resort. Species constancy represents an indicator that is assessed through the values of the frequency. Depending on the frequency range, herbaceous species within Bălți urban ecosystem were classified into the following categories: Euconstant – with frequency values of 75 – 100 % – 16 species, (11 %). The most frequently encountered are the ruderal and segetal – ruderal species (Bromus arvensis L., Polygonum aviculare L., Chenopodium album L., etc.); Constant – whose frequency values of 50 – 75 % – 12 species, (8 %). The following species were included in this category: Cychorium intybus L., Ambrosia artemisiifolia L., etc.; Accessories – species with frequency of 25 - 50%, known as companions of the urbanization process. Were reported 37 species (25 %): spontaneous (Trifolium fragiferum L., Butomus umbellatus L., etc.) and ruderal (Caucalis platycarpos L., Plantago lanceolata L., etc.); Accidental species – with frequency of 0 – 25 % – are often species that accidentally ended up on the territory of the city were recorded. This category includes 85 accidental species (56 %): segetalruderal, ruderal, and spontaneous species (Ajuga genevensis L., Salvia nemorosa L., Urtica dioica L., etc.), the latter being at an advantage.
