Ecological Condition of the Sapalayivka River in the Conditions of Lutsk Urbosystem
Abstract
Purpose. Determination of the main factors of anthropogenic impact of the urban system of the city of Lutsk on the river basin of the river Sapalaivka and assessment of the ecological condition of the river on the basis of MIR "Macrophytic index of rivers".
Methods. Comparative-geographical, generalization, systematization, statistical, comparative-analytical, descriptive, cartographic.
Results. In the Sapalaivka River, 21 indicator species of macrophytes were found in the surveyed test areas, among which - 8 plants belong to dicotyledons, and 13 plants belong to monocotyledons, using which the
MIR values were calculated. Depletion of macrophyte species composition from 15-16 in test plots 1 and 2 to 2 species in test plot 3 indicates deterioration of the ecological condition of the river and the emergence of unfavorable conditions for macrophyte habitats. On the territory of the city, the section of the Sapalaivka riverbed, from the beginning of Potapova Street to the mouth, is mostly canalized, the species composition of macrophytes is depleted here and there is a specific smell of sewage. The part of the river that flows in the city (before Potapova Street), which was renaturalized in 2012-2016, has a richer species composition of macrophytes. Outside the city, the Sarpalaivka river basin is in good condition, as evidenced by the species composition of flora and fauna, as well as the intensive development of higher aquatic vegetation.
Conclusion. As a result of the calculated ecological index of macrophytes MIR it is established that the water quality in the river Sapalaivka on the test site № 1, belongs to the II class, category - good and by trophic status is mesotrophic; on the test site № 2, belongs to the III class, category - satisfactory and eutrophic in trophic status; on the test site № 3, belongs to class IV, category - poor and trophic status is polytrophic. It is advisable to carry out further environmental measures, especially in the lower reaches of the river, in order to eliminate sources of water pollution, and to monitor the ecological status of the reservoir in order to restore the species composition of macrophytes and the ability to self-clean.
