The present paper presents the results regarding the role of the ecological infrastructure in the Balti urban ecosystem in the provision of ecosystem services. Modern methods of land use analysis were used, followed by the quantification of ecosystem services (air purification, carbon storage, water retention). It was established that in the municipality of Balti, agricultural land predominates - 51% (4001.44 ha), followed by construction and courtyards - 28% (2138.25 ha), forests -9% (722.75 ha) , lands occupied by water and lands for streets and markets with 4% each, roads - 3%, and other lands including degraded. In the rural area, agricultural land predominates, and in the urban area - buildings and yards. The urban green infrastructure in the Balti urban ecosystem can remove approximately 51.6 t/year of particles from the air, store 116.5 thousand tons of carbon and retain rainwater in case of 10 mm precipitation - 289.8 thousand t/ year.
