Statistical Criteria

В статье обосновывается предложений способ оценки экологического состояния пресноводных водоемов на основе космического геомониторинга и статистического критерия одновременно по нескольким эталонам, каждый из которых представляет соответствующий уровень техногенного или антропогенной нагрузки. Для этого по каждому изучаемому объекту (водоему) вычисляют вероятности соответствия их информативных признаков информативным признакам каждого эталона. В результате получают количественную оценку влияния нагрузки в относительных единицах или баллах. Приведены примеры апробации предложенного метода для исследования изменения экологического состояния водоемов на примере Киевского водохранилища и озера Свитязь.Для обоснования предложенного способа было определено соответствие полученных результатов на основе статистического критерия оценкам реальной рекреационной нагрузки и оценкам влияния нагрузок полученных методами МКО и МАИ. Для этого были подсчитаны коэффициенты корреляции между этими результатами за соответствующие годы, который в среднем был ровен 0,8, что вполне приемлемо для практических оценок результатов нагрузки на экосистему водоемов. Установлено, что водные объекты представляют собой сложные системы, анализ которых происходит на разных уровнях абстрактного описания с учетом взаимосвязи их составляющих: ландшафтных комплексов (ПТК или биотопов), гидрологических, гидробиологических и гидрохимических характеристик. В ходе исследования выяснено что рекреационная нагрузка на озеро Свитязь постоянно растет и соответственно негативно влияет на его экологическое состояние. Также выявлено, что зарастание акватории верховья Киевского водохранилища высшей водной растительностью также увеличивается, что в свою очередь ослабляет эффективность водохранилища для нужд водопотребления. The article substantiates the method of assessing the ecological status of freshwater reservoirs using space geomonitoring and statistical criteria with several standards simultaneously, each of which represents the level of technogenic or anthropogenic load. To achieve this, the probabilities of the affiliation of their informative features to the informative features of each standard are calculated for each studied object (reservoir). The result is a quantitative estimation of the load, which is given in relative units or points. The approbation of the offered method for research of the changes in ecological conditions of reservoirs is done over the Kyiv Reservoir and lake Svityaz.During the study of the method, the correspondence of the obtained results using the statistical criterion to the real estimates of recreational load made by the method of multi-criteria optimization (MCO) and method of analysis of hierarchies (MAH) was determined. For this purpose, the correlation coefficient between the obtained result and recreational load, as well as the results of assessments based on MKO and MAH for the respective years was calculated, which averaged 0.8, which is quite acceptable for practical assessments of water ecosystem load. It was determined that water bodies are complex systems and their analysis takes place at different levels of abstractions, taking into account the relationship of their components: landscape complexes (LC), hydrological, hydrobiological and hydrochemical characteristics. The study found that the recreational load on Lake Svityaz is constantly increasing and has negative impact on its ecological condition. It was also found that the overgrowing of the upper springhead of the Kyiv Reservoir with higher aquatic vegetation is also currently increasing, which weakens the efficiency of the reservoir for purposes of water consumption.

The following paper deals with a methodical approach and experience of water quality complex index ( Iwq ) use for the evaluation of ecological status of surface water bodies by results of rivers monitoring within the Middle Ob basin during 2002-2018. This index allows to use such primary information as results of water chemistry analyses, parameters of structure of microbial community and other available data obtained for each sample site on various water bodies within the basin. The main evaluation criterion for calculating this index is a degree of a deviation of each controlled indicator from average value of this indicator for all explored water area within the basin. Water bodies (or their sites) can be classified to 5 various classes of water quality using the calculated values of the index. Such a methodical approach allows to carry out comparative estimation of an ecological condition of water bodies and their sites within the area, to map the obtained data, to analyze possible reasons of deterioration of water ecosystem state, to manage decisions on their restoration. The paper presents the results of the water quality complex index use for rivers within the Middle Ob basin, calculated on the base of indicators of the chemical composition of water and number of bacteria of various ecological and trophic groups in the structure of microbial community.

The Impact

According to field research, cartographic works and satellite images, the main hydroecological features of water bodies on Zhukov Island in Kyiv have been studied. Information on the history of the impact of economic activity on this area is given. The first object affected the water bodies, located on the island, particularly for the Konyk river arm, was a railway tunnel, which was under construction in the late 1930s and early 1940s. Another factor was the construction of several roads. As the result of this construction the former Konyk river arm actually turned into the lake. Significant changes in this area were observed in the mid-1970s after the constriction of the Kanivske Reservoir. The increase in the water level in low water conditions by about 2.5 m caused an increase in the size of existing water bodies and the emergence of new ones. The description of the largest lakes in the studied area is given. For today they are a complex system of lakes in this area, hydraulically connected with the Dnipro River. At the same time, water exchange in the lakes and between the lakes and the river is insignificant. First of all, this is due to the low capacity of the existing hydraulic structures and clogging of ways to them. In fact, there is the only one hydraulic structure on the river bank through which water can reach the lakes. In addition, low water runoff of the Dnipro River in recent years also causes a negative impact on this ecosystem. Recently, intraday fluctuations of water discharges at the Kyiv HPP have decreased, and respectively the fluctuations of water levels in the Dnipro River near the studied area also decreased. This negatively affected the ecological condition of the lakes, which are intensively overgrown. In addition, wastewater inflow into one of the largest local lakes, namely Konyk, has a negative impact. The indicators of bottom sediments in this lake are given, which testify to its pollution by heavy metals. The typical species of aquatic and air-aquatic vegetation inherent to the lakes on Zhukov Island are characterized. The recommendation, which can improve water exchange in the lakes and their ecological status, are given. It was considered that the nature protection activity in this area can be improved in case of adding the created here landscape reserve to the National Nature Park “Holosiivskyi”.

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.

Neva Bay

The macrophyte thicket ecosystems of higher aquatic vegetation in the Neva Bay (NB) and Eastern Gulf of Finland (EGoF) perform many important roles, including acting as the habitats, nesting sites and migration sites for aquatic and semi-aquatic birds, creating the specific conditions necessary for the spawning and growth of many species of fish, and taking part in the self-purification of the aquatic ecosystems. Many anthropogenic disturbances, hydraulic works in particular, have a significant negative impact on these macrophyte thicket ecosystems. In recent years, the active growth of a new type of macrophyte thicket has been observed in the NB. This is due to the aftereffects of the construction of the Saint Petersburg Flood Prevention Facility Complex (FPFC). It is quite likely that the total macrophyte thicket area in these waters is currently increasing. In the future, it will be necessary to assess the environmental impacts of the hydraulic works on the macrophyte thicket of the NB and EGoF, taking into account the background processes of the spatiotemporal dynamics of the reed beds in the waters in question. To do this, it will be necessary to carry out a comprehensive study of these ecosystems and identify patterns in their spatial and temporal dynamics. The program of the study has been developed and is currently being implemented by Eco-Express-Service, a St. Petersburg eco-design company.

Designing environmental flows in lowland river sections and estuaries is a challenge for researchers and managers, given their complexity and their importance, both for nature conservation and economy. The Ebro River and its delta belong to a Mediterranean area with marked anthropogenic pressures. This study presents an assessment of the relationships between mean flows (discharges) computed at different time scales and (i) ecological quality based on fish populations in the lower Ebro, (ii) bird populations, and (iii) two shellfish fishery species of socioeconomic importance (prawn, or Penaeus kerathurus, and mantis shrimp, or Squilla mantis). Daily discharge data from 2000 to 2015 were used for analyses. Mean annual discharge was able to explain the variation in fish-based ecological quality, and model performance increased when aquatic vegetation was incorporated. Our results indicate that a good ecological status cannot be reached only through changes on discharge, and that habitat characteristics, such as the coverage of macrophytes, must be taken into account. In addition, among the different bird groups identified in our study area, predators were related to river discharge. This was likely due to its influence on available resources. Finally, prawn and mantis shrimp productivity were influenced up to a certain degree by discharge and physicochemical variables, as inputs from rivers constitute major sources of nutrients in oligotrophic environments such as the Mediterranean Sea. Such outcomes allowed revisiting the environmental flow regimes designed for the study area, which provides information for water management in this or in other similar Mediterranean zones.

In the digital era, the success of the professional development of future specialists in the process of obtaining higher education largely depends on their professional orientation (PN). Despite the significant interest in the subject of the study, the problem of identifying the factors that affect PN remains poorly understood. The purpose of the study is to determine the factors of the formation of PN of students enrolled in training and retraining programs, and the features of PN in the digital era. The article reveals the content and structure of the PN of future specialists in the era of digitalization. According to the results of the empirical research, the relationship of students' PN with indicators of life-meaning orientations, motives for choosing a profession and training was revealed; the relationship between students' life-meaning orientations and indicators of motives for choosing a profession and training at the stage of digitalization of education. The factors influencing the personal condition, and the factors of the formation of the personal condition of students, who are trained according to the programs of training and retraining of specialists, have been determined. As a result of an empirical study, it was concluded that a negative impact on the formation of PN is created by factors caused by various life circumstances, lack of independence of decisions in choosing a profession, low reflection of life goals, prospects for the future, rigidity of volitional and personal qualities, internal conflict in the structure of personality relationships, low pleasure training and the like. At the same time, the level of PN is significantly higher among students who receive a second higher education and who understand its importance at the stage of digitalization of education.

National Nature Park “Pyryatynsky” is a valuable reserve of flora and vegetation of the Left-Bank Dnipro. The extensive hydrological network of the Udai River and the wide representation within this nature reserve of floodplain reservoirs are the reason for the high diversity of plant communities of higher aquatic vegetation. In this article we classified the communities of order Callitricho-Batrachietalia in National nature park "Pyryatynskyi" and identify the features of their syntaxonomic and ecological differentiation. Fragmentary and non-comlete information about this type of vegetation are existed in literature, however, without geobotanical releves and detailed characteristics of the structure of phytoceonoses, synecology and synchorology. All obtained results based on original field data. In total, 22 geobotanical releves were performed during the period 2010–2017. The description of communities was carried out within their natural boundaries. Treatment of fitosociological data was performed with the JUICE software package. The nomenclature of syntaxons was consistent with the International Code of Phytosociological Nomenclature (ICFN).The order of Callitricho-Batrachietalia on the territory of NPP "Pyriatynsky" is represented by alliance Batrachion aquatilis Gehu 1961 and 4 associations (Batrachietum aquatilis Gehu 1961, Potameto perfoliati–Batrachietum circinati Sauer 1937, Hottonietum palustris Sauer 1947, Veronico beccabungae–Callitrichetum stagnalis (Oberdorfer 1957) Th. Müller 1962). This is first prodrome of order Callitricho-Batrachietalia for territory of National Nature Park “Pyryatynskyi”. The communities of this syntaxon occupy small areas and have a limited distribution in the region. Most of them are rare and vulnerable to changes in environmental conditions. Monitoring of their structure, chorology and dynamics is an important task to maintain and preserve the species and coenotic diversity of NPP "Pyryatynsky".
