Abstract

The tourism industry is concentrated within the boundaries of the Subcarpathia Forestry District of Ukraine. These are mostly resort complexes with recreation houses, hotels and restaurants. Since the issue of solid household waste processing has not been resolved in Ukraine, landfills are emerging near recreation facilities. Undoubtedly, such a situation contradicts the improvement processes, because landfills are objects of detonation of dangerous substances and compounds getting into all components of the environment due to geochemical flows. It was established that chemical elements of the toxic group and biogenic elements accumulate. The traces of individual elements were also determined. The Bronytskyi landfill is the most polluted with the following chemical elements: Pb (3.56 - 4.06 mg/kg), Zn (2.84 - 3.67 mg/kg), Gd (0.021 - 0.033 mg/kg), P (457.3 – 609.7 mg/kg), K (9.7 – 14.6 mg/kg), Ca (174.7 – 237.7 mg/kg), Ga (3.58 – 5,98 mg/kg), La (1.09 – 1.24 mg/kg), Y (0.013 – 0.014 mg/kg), Cd (0.15 – 0.176 mg/kg), Sn (0.013 – 0.018 mg/kg ), Nd (0.029 – 0.046 mg/kg), Eu (0.022 – 0.036 mg/kg) and Th (0.05 – 0.078 mg/kg). The site of the Boryslav landfill is most polluted in the western side - Fe (16.06 - 19.72 mg/kg), Cu (0.37 - 0.43 mg/kg), Gd (0.003 mg/kg), Si (43 – 58.2 mg/kg), P (782.4 – 995.5 mg/kg), Ca (88.6 – 104.7 mg/kg), Mn (1.7 – 2.7 mg/kg) , Sc (0.009 mg/kg), Cr (1.069 – 1.255 mg/kg), Y (0.015 – 0.016 mg/kg), Nd (0.016 – 0.018 mg/kg). In the eastern side of the Stryi landfill the presence of the following elements is most evident - Fe (18.98 - 27.97 mg/kg), Ni (0.09 - 0.21 mg/kg), Zn (0.14 - 0.19 mg/ kg), Pb (0.05 - 0.1 mg/kg), Al (1.6 – 2.0 mg/kg), P (718.1 - 652.5 mg/kg), Mn (2.5–3.5 mg/kg), Ga (0.01 mg/kg), La (0.02–0.04 mg/kg), Cr (0.009–0.013 mg/kg), Ge (0.214 – 0.551 mg/ kg), Cd (0.014 - 0.02 mg/kg), Nd (0.017 - 0.037 mg/kg), Th (0.009 - 0.016 mg/kg). Such a detailed chemical analysis for the presented objects of research is carried out for the first time.

Abstract

Coal spoil-heaps cause man-made pressure on the environment of the coal mining area. Coal mining, and in recent years the mass closure of mines has been accompanied by a negative impact on natural objects and engineering structures - the basements of houses and buildings are flooded, walls and wooden fences rot, crops, trees and bushes are destroyed. Reclamation is carried out on spoil-heaps of coal mines to reduce man-made pressure. However, in the process of rock dumping on the spoil-heaps a neorelief begins to emerge causing the vegetation development. The emergence of vegetation groups is a positive phenomenon, as phytomass decomposition promotes the formation of humus. The development of vegetation on the surface of coal spoil-heaps is called vegetative reclamation or phytomelioration. Efficiency of vegetative reclamation is calculated in points and is an indicator of the suitability of a particular man-made object for natural overgrowth. The aim of the work is to establish the features of spatial arrangement of plants in populations on the surface of coal spoil-heaps. It is established that on the coal spoil-heaps, as well as in natural conditions, vegetation tends to aggregate, thus forming phytogenic fields. It should be noted that at different stages of successions, phytogenic fields are formed in different ways. Monocentric phytogenic field arises on the waste heaps during the syngenetic stage of succession. The initial endecogenetic stage of succession provides the formation of phytogenic fields of two types. The first type is the initial polycentric phytogenic field. It is characterized by the ability to combine several individuals of the same species. The second type is a mature polycentric phytogenic field. It is characterized by higher resistance, and plant community is already able to convert geoprocesses. The mature endoecogenic stage of succession is characterized by the development and expansion of tree species, and the phytogenic field is acentric and global. This kind of phytogenic fields is found on tailings with artificial vegetative reclamation.

Abstract

Objective of the study is to research peculiarities of phytogenic fields formation of natural and artificial plantations of shrub and ruderal vegetation on coal mining waste heaps within the Novovolynsk mining area (Ukraine). The biometric analysis of the growth of artificial plantations on tailings has been carried out applying forest inventory methodology, which involves laying temporary experimental areas, measuring the diameter of tree species at a height of 1.3 m, the total height of trees and the parameters of crowns. Variation was applied to study the spatial structure of vegetation on reclaimed and damped waste heaps. The models of artificial phytocenoses and ameliorants on waste heaps of coal mines, which are formed during forest reclamation, have been described. The paper presents an analysis of forest inventory characteristics of the crops phytocenosis on waste heaps. The spatial structure of phytogenic fields basing on variation of the most common species in natural and artificial plantations on waste heaps has been established. This allows us to select an assortment of species to conduct effective vegetative reclamation on the surface of tailings. The article presents result of studies on the formation of phytogenic fields on waste heaps of coal mines, which presuppose formation of aggregations. It has been proved that formation of phytogenic fields is inextricably connected with vegetative reclamation. The conducted research of the origin and distribution of phytogenic fields makes it possible to assess the degree of suitability of tailings for afforestation, regardless of the country in which they are formed. Research of phytogenic fields on tailings and waste heaps of coal mines will improve bioindication research methodology for studying forest crops on their surface and suggest innovative methods of handling. In particular, it is possible to raise the level of environmental safety and aesthetics of the devastated territories, and to reduce cost of vegetative reclamation.
