It is established that the largest amount of fresh phytomass is recorded upstream of the city. Bălți (1998 g / m2), which is explained by the fact that, upstream of the city, the anthropogenic impact is minimal. A large amount of dry vegetable mass was determined on the bank of the tributary of the river Răut - Flămânda, (960 g / m2), fresh phytomass (1850 g / m2), and organic mass (50 g / m2). This is due to the fact that there are no houses nearby and the anthropogenic impact is minimal and the soil is fertile. The lowest amount of fresh phytomass (840 g / m2) and the lowest amount of organic matter (18 g / m2) are recorded near Lake Komsomol. The dry phytomass of the grass layer of this resort is also small (170 g / m2). These results are caused by the fact, that there are houses nearby, the soil is pounded and the plant diversity is subject to an essential anthropogenic impact.
