Contemporary urban ecosystems represent ecosystems with genesis and microevolutionary processes, it includes a varied spectrum of different taxonomic groups of plant and animal organisms, which occupy certain ecological niches of the urban ecosystem. In order to develop a management plan, it is necessary to know in detail the green spaces in the urban area from a quantitative and qualitative aspect, which primarily involves the study of: the total area of green space in the urban area, the weight of the area of green space compared to the total surface of the urban area, the surface of green space per a person, floristic study and the productivity of the grassy layer. The floristic study of this ecosystem indicates that the flora was formed by the penetration of spontaneous autochthonous species, which adapted to the conditions of the urboecosystem, and of allochthonous species, who entered the territory of the Republic of Moldova by different routes. Fresh phytomass provides information about the state and capacity of the ecosystem. The productivity of the grassy layer within the Balti urboecosystem differs depending on the activity of the anthropogenic factor.
