Methods of research: field (geobotanical descriptions), remote and laboratory analysis (determination of physiological and biochemical state and spectral values of the plants from contaminated areas). The purpose of the work: development of information technologies for monitoring the ecological status of wetlands in real time, taking into account the pollution of the environment by heavy metals and petroleum products, based on the definition of a system of stable identification markers of anthropocentric pollution of water bodies based on the results of terrestrial spectroscopy of aquatic vegetation, comparison of these indicators with vegetation indices, computed from satellite data, and physiological and biochemical analysis of hydrophytes, grown in lakes and reservoirs, polluted by petroleum products and heavy metal ions. During the stage, three sections of the wind farms with different ecological characteristics were selected: 1. A control site with no pronounced anthropogenic impact near the village Protsiv in the Pavlovka River area; 2. A swamp site near the Solid Waste Management (Waste Management) No. 5 near the village of Podgortsy, exposed to harmful compounds that are washed away into the soil from waste; 3. Plot in the area of the drainage channel of the Border Station of aeration. Here the vegetation suffers from the residues of liquid waste and other products that remain in the water after cleaning. A geobotanical description of the selected sites was made, dominant vegetation types were determined. The model experiments identified changes in the pigment complex at the Ceratophyllum demersum under the influence of high concentrations of copper and chromium. In laboratory conditions, based on soil spectrometry with ASD FieldSpec® 3FR, it has been shown that hydrocarbon indices HI and HD can serve as indicators of petroleum contaminated soils without vegetation cover. In the presence of local minima at the wavelengths of 1720-1750 nm, 2310-2350 nm in the reflectance spectra of the soil surface when contaminated with oil, these indices assume the values HI> 0 and HD> 1.The camera for measuring ecosystem flows CO2, which will be used to determine respiration ecosystems (ER, Reco) - the sum of respiration of autotrophs and heterotrophs; clean ecosystem carbon exchange (NEE) - the difference between GEP and respiration of the ecosystem (Reco) GEP - the amount of CO2 absorbed by plants in the process of photosynthesis, as well as soil respiration (Rsoil), consisting of autotrophic (respiration of plant roots) and heterotrotrophic (soil microorganisms) parts. During the reporting period, 2 articles and 1 abstracts of the international conference were published.
