Kulyk","doi":"10.26565/1992-4224-2021-36-06","DOIUrl":"https://doi.org/10.26565/1992-4224-2021-36-06","url":null,"abstract":"Purpose. The identification of soil indicators for assessing the forest growth potential of soils for the possibility of afforestation.\u0000\u0000Methods. The indicators were chosen among the soil parameters most often used to assess fertility: reserves and thickness of forest litters, morphological characteristics of soils, particle size distribution, acidity, humus and various forms of NPK content, composition and content of exchangeable cations. The research was carried out in natural medieval forests according to the methods generally accepted in forest inventory, typology, soil science, analytical work - according to classical agrochemical and standardized methods. \u0000\u0000Results. The article gives an analysis of the problem of forestry typological evaluation of low-output and degraded soils (sandy, with shortened profile, salted, eroded), which were withdrawn from agricultural usage. The actual and theoretical material on the basis of which the range of issues related to the evaluation of forest land use in different natural zones is generalized, was collected and analyzed. On the main categories of low-productive lands in different natural zones of the flat part of Ukraine temporary trial areas were laid, where soil and typological investigation were conducted. The soil indicators and parameters of forest productivity of low productivity and degraded soils are determined, on the basis of which the classification of soils based on the degree of their suitable for afforestation has been developed. The suitability of soils for afforestation were evaluated in three categories: suitable for afforestation, limitedly suitable and unsuitable suitable for afforestation.\u0000\u0000Conclusions. The experience of afforestation of low-productive and degraded soils is generalized and a system of diagnostic indicators for their forest typological evaluation on zonal and morphological basis is proposed, and an information analysis on the problem of assessing the suitability for afforestation of low-productive lands (saline, stony, sandy) that are derived from agricultural circulation is provided. The suitability of soils for afforestation is described by a system of soil indicators, in particular, their particle size distribution, humus content, common and mobile forms of NPK, and exchangeable cations. However, among these indicators, one can single out informative indicators of the level of productivity of forest lands - mineralogical (chemical) and granulometric composition of soils. At the same time, it has been proved that the granulometric composition of the soil determines such important characteristics as the content of exchange bases, common forms of phosphorus, potassium, and humus.","PeriodicalId":166012,"journal":{"name":"36","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133371704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The basic cartographic document for the study was a scanned map at a scale of 1:50 000 showing the boundaries of the Gomilshansky Forests National Park from the National Nature Park (NNP) Project. The main problem was the lack of elements of its mathematical basis on the map. The IT technology of geo-linking the scanned map of the park boundaries in the GIS environment includes the following actions: linking topographic map sheets at a scale of 1: 50,000 in the ArcGIS geographic information system, saving the relevant geo-linked, transformed copies of the image; visualization of digital geodata with geometry and coordinates of points of boundaries of forest areas (quarters); download the scanned map of the boundaries of the NNP from the Project of creation without geographical reference and perform the procedure of sequential addition of control points of reference; image transformation and saving the result in geotiff format. After that, a polygonal vector layer of * shp format was created and the park territory was digitized according to the NNP Project.

To calculate the amount of POPs inflows into the environment, we use an updated European methodology for the inventory of pollutant emissions «EMEP/EEA air pollutant emission inventory guidebook (2019) ».\u0000\u0000Results. The priority sources of waste accumulation containing polychlorinated biphenyls (PCBs) in Odesa region are identified and analyzed; the availability and state of programs implementation for the detoxification of unusable РOPs-containing pesticides in the Odesa region is estimated; specific masses of POPs-containing pesticides per capita in each districts are determined; according to the value of specific masses of pesticides, priority districts for organization of measures to detoxify POPs-containing pesticides are arranged and identified; using the updated European methodology, the volumes of PCB leaks from PCB-containing equipment and the volumes of PCB inflows into the environment (soil cover and air basin) are calculated; the results are ranked and priority districts for detoxification of PCB-containing equipment and, as a result, effective implementation of the Stockholm Convention are identified.The largest share of pesticides falls on the residents of Savran (2,660 kg/person), Biliaivka (2.47 kg/person), Kodyma (2,082 kg/person) and Liubashivka (1,197 kg/person) districts, which should become a priority in the program for detoxification of unusable POPs-containing pesticides.\u0000\u0000 Conclusions. The existing legal base and methodological framework is not enough to effectively implement the requirements of the Stockholm Convention. The program for the detoxification of unusable POPs-containing pesticides for 2018 has not been implemented. So pesticides that are stored incorrectly in the vast majority of cases, are a probable source of PCBs for residents in which districts pesticides are localized The largest contribution to the supply of PCBs from electrical equipment falls on Odesa – 49.2% of the total PCBs mass coming into the environment from this source.

Carry out hydrological zoning of the Southern Buh river basin with the allocation of areas with the same conditions for the spring floods formation by a set of morphometric characteristics of rivers and their basins and hydrometeorological and agrometeorological factors.\u0000\u0000Methods. Using a statistical model of factor analysis (R-modification) the most significant factors from the totality of all features were identified. There are two factors – the first describes 38% of the total variance of all factors (latitude of catchment centers, average height of catchments, wetlands, water reserves in the snow cover, precipitation of snowmelt and maximum depth of soil freezing), and the second – 21% (river length, catchment area and the amount of precipitation that fell after snowmelt). Factor loads were used for further grouping of basins using the method of cluster analysis. \u0000\u0000Results. As a result of territory zoning, two hydrological districts with sub-districts (district I and district II with sub-districts IIa, IIb, IIc) were identified. Area I covers the area from the source to hydrological post on the Southern Buh river basin – Trostyanchik village. Downstream and to the river mouth, the territory covers area II, which is divided into three sub-areas (sub-area IIa, IIb, IIc). Data from small rivers between the Dniester and the Southern Buh are involved in the hydrographical network. The boundaries of hydrological districts in the Southern Buh river basin were drawn along the watersheds of rivers, taking into account the physical and geographical zoning of the territory and involving in the analysis of maps of soil cover and vegetation in the basin.

To substantiate the calculated characteristics of the slope influx and channel runoff, as well as to create a modern methodological basis for rationing the characteristics of the maximum runoff of spring and rain floods in the Vistula River basin within Ukraine.\u0000\u0000Methods. For calculating the maximum runoff of spring and rain floods, statistical processing of data series was performed according to the method of moments and the maximum likelihood method. The three-parametric gamma distribution was used to calculate the runoff layers and water discharges with a rare probability of exceeding. An operator model developed by E.D. Gopchenko (2001) and modified by V.A. Ovcharuk (2017) was used as a calculation to determine the characteristics of the maximum river runoff. To calculate the duration of the slope influx, a complex method was used using the software complex \"Caguar\", developed at the Department of Land Hydrology of OSENU.\u0000\u0000Results. The standard statistical characteristics of the time series of the maximum runoff of spring and rain floods are determined, they were used in further calculations to determine the maximum water runoff and runoff layers with a rare probability of exceeding. The paper substantiates and generalizes on the territory all parameters of the basic operator model of maximum runoff formation: coefficients of time non-uniformity of slope influx and duration of slope influx are determined, transformation function is calculated and maximum modules of slope influx for spring and rain floods are determined.

The research was conducted in 2017–2019. As a result, 40 species of 25 genera, 14 families, 7 orders, 2 classes, and 1 division were registered. A taxonomic analysis showed that the orders Hypnales (14 species), Pottiales (9 species) and Bryales (9 species) are represented best. The main families were as follows: Pottiaceae (9 species), Brachytheciaceae (7 species), Bryaceae (5 species), Amblystegiaceae and Mniaceae (4 species each). The most speciose were the genera Bryum (5 species), Brachythecium (4 species), Tortula (4 species) and Plagiomnium (3 species). Among the identified taxa, two species, (Barbula сonvoluta and Bryum rubens) are regionally rare in the Forest-Steppe zone of Ukraine. In the historical part of Olexandria, five species Ceratodon purpureus, Oxyrrhynchium hians, Hypnum cupressiforme, Atrichum undulatum, and Bryum moravicum were the most common epigean bryophytes. In the western part of the Dendropark, the prevalent species were Atrichum undulatum, Bryum moravicum, Oxyrrhynchium hians, Hypnum cupressiforme, Brachytheciastrum velutinum, and Hygroamblystegium varium, in the central part – Bryum moravicum, Hypnum cupressiforme, Ceratodon purpureus, and in the eastern part – Fissidens taxifolius, Fissidens viridulus, and Brachythecium rutabulum. Twenty species (50 % of the identified taxa) were obligate epigees while the other 20 species belonged to the facultative epigees.
