The area of technogenic territories in the Russian Far East and Siberia continues to increase. The aim of this article is show the degree of reforestation processes scrutiny in mining landscapes of the Russian Far Eastern region. The results of technogenic landscapes research of the Russian Far East are represented by extensive set of knowledge, accumulated over half a century, and highly of disparate in resent time. They are not extensive as the results of studies of natural landscapes, but have important practical importance. Time of mining influence in the landscapes of the Far Eastern region is relatively small, and makes some decades in most cases. Therefore, the results of most studies belong to early, at least middle stages of ecological successions. Floral features of mining areas are thoroughly characterized. Many papers are devoted to the regularities of self-healing vegetation. Questions of recultivation are considered for each site individually. It is recommended to provide forestry, recreation, sanitation and meliorative restoration that assume different recultivation schemes. The selection of wood species is commonly recommended from the number of native species, because they are better adapted for local growing conditions. Compiled the lists of tree species, most successfully surviving on the dumps. In the presence of fairly extensive scientific literature, detailed studies of the structure and dynamics of disturbed areas are few in number. In particular, the facies structure of technogenic territories have not been studied, the recovery process of vegetation differentiated for different types of habitats were not considered and there are no detailed landscape and geobotanical maps of disturbed areas. Unfortunately, monitoring studies of natural and artificial reforestation are not developed.

The investigation of processes of recovery of disturbed land at the urban areas is a new, urgent problem for industrialized centers. Currently disturbed areas where recovery operations are conducted by various reclamation technologies are within the city of Novokuznetsk area in Kuznetsk Basin. Monitoring investigations to determine their environmental condition and the level of natural ingredients recovery have not been conducted at these areas until recently. The lack of such information does not allow efficient analysis of the conducted reclamation activities and determination of the prospects for recovery and further use of such land. The paper presents the results of an investigation of forest plantations and areas with natural revegetation of disturbed areas, and the complex of soil studies to determine the basic physical and agrochemical characteristics of young soils formed on the disturbed surface is conducted. Based on these studies the vegetation and soil cover were characterized and the soil-ecological condition of the reclaimed areas from the 1970’ stailings pile of «Baidaevskij» coal mine was assessed. As a result of reclamation activities, the sites with different plant communities are formed at the tailings pile surface. Botanic composition at the reclaimed areas represented species able to operate successfully in a technogenic landscapes. Because the grand dump territory is reclaimed by the forest approach the statement of forest is characterized by the special aspects, such as high density of planting with little crown density, high opacity and low level of stable forest recovery. The tailings pile sites reclaimed by different methods are characterized by specific soil-ecological condition, which can be used to assess the efficiency of reclamation. Soil-ecological assessment of the conducted reclamation efficiency is carried out on the basis of assessment of the soil, formed on the surface of the disturbed area. The more developed phytocoenosis formed in more developed soil areas, and therefore the better soil-ecological condition takes place after reclamation activity. The main tailings pile area is characterized by the satisfactory and good soil-ecological condition. This demonstrates that the currently formed natural-technogenic complex successfully functions that allows this area to carry out protection functions within the territory of city.
The paper present the results of study of the floristic composition and importance of species of aquatic ecosystems on different types of technogenic surfaces of the Borodino coal mine and assessment of the impact of local factors on the structure and the dynamics of vegetation. The list of plant taxa containing 91 species of higher plants and 3 charophytes. The largest amount of macrophytes species are Elodea canadensis Michx. , Eleocharis palustris (L.) Roem. & Schult. , Hydrocharis morsus-ranae L. , Potamogeton alpinus Balb. , P. perfoliatus L. , Sparganium emersum Rehm. , Spirodela polyrhiza (L.)

Braun ex Kutz., the basis (up to 67.6-70.9 %) of vegetation mosaic of aquatic systems and differentiate its structure posttechnogenic landscape. Sorensen index ( QS = 0.63-0.71) and Spearman rank correlation coefficient ( rs = 0.29-0.62, p < 0.01) values showed the greatest similarity between the species composition of the aquatic complexes arising on mineral surfaces planned dumps. The low level of similarity ( QS = 0.13-0.45; rs = 0.25-0.34, p < 0.05) in species composition is typical fir ponds and wetlands formed around the perimeter of the heaps along the erosion of slopes. Non-parametric analysis of variance showed a statistically significant ( p < 0.001) differentiation of the species composition of the variables values of the analyzed environmental factors: the direction of reclamation, type and age of geomorphic surfaces dumps. Aquatic complexes significantly complement and enrich the mosaic of man-made landscape of the Borodino coal mine, the potential of their diversity should be taken into account when developing plans and strategies for reclamation of disturbed areas.

State of forest stands, which were originated naturally on mechanically disturbed moor-forestry lands near oil and gas complexes of Surgut Poles’e (Western Siberia) is estimated in the paper. The differences of their timber value from natural stands are also discussed. Newly originated forests on the higher relief technogenic positions differ significantly from natural stands not only by their productivity, but also by their structure and biological diversity. It gives full possibility to call them technogenic forests. ft was unexpected, but the raised role of such forests opened potential productive forces of the Surgut Poles’e. This role showed a necessity of cardinal revision of forestry principles and natural protection of moor-forestry ecosystems. The state of compound technogenic forests witness positive consequences of the destruction of soil cover and significantly surpass the soil damage. Due to this fact, it is necessary to study deeply this phenomenon. The new data concerning this phenomenon will be a scientific development for creation a new normative base for rational natural use and re-cultivation of disturbed forestry parts of Western Siberia.

The article considers the issues of the restoration vegetation on the dumps of the coal enterprises of the Kuznetsk Basin. Studies have shown that the dumps have a wide range of environmental conditions and are potentially suitable for establishment of plants. To negative environmental factors at the mine dumps include the lack of productive moisture, failed penetration, contrasting temperature regime on the different elements of the relief, and low potential fertility of the embryonic soils. Positive - high humidity in the depressions, the high content of fine-grained deposits in the lower part of the elephant dumps, excessive accumulation of snow in the winter on separate dumping sites. On disturbed lands identified eight technogenic ecotopes, characterized by various microrelief, moisture level, amount of fine fractions of technogenic eluvium determining favorable, moderately favorable and unfavorable conditions for vegetation of disturbed land. Selected three stages of syngenesis: pioneer stage, simple plant communities and complex plant communities. The stage of zonal phytocenosis on the dumps was not detected. The basis of diagnostic signs consists of the projective cover, the nature of the host plants, the number of species part of the zonal species. The selected criteria are universal and can be applicable to most dumps. Speed of syngenetic succession does not depend on calendar age of the dumps, and environmental conditions, which are formed on separate sites.

The test groups of animals showed different reaction on the presence of electric power line (EPL) glades, which cross light and dark conifer formations. The microarthropods react on the changes of hydrotermic soil conditions in a higher degree. The direct influence of electromagnetic field on the population density of soil invertebrates has place in both forest formations, but with opposite consequences. The same is demonstrated by herpetobium elements: the clear dominance of «meadow» species in fir formations and the absence of this in pine parts. Small mammals on the LEP glades increase their abundance and species diversity. They also demonstrate that their distribution is dominated by food and protection conditions. But at the same time, the distribution of constant rodent winter refuges demonstrate the negative effects of EPL existence. The analysis of bird populations on the basis of optimal life conditions demonstrated a highest negative effect of electromagnetic field of EPL. Independently of the creation of good protection, food and nesting conditions for birds, which usually occupy open biotopes and bush with herb thickets, they avoid the EPL glades. The first results showed the dual effect of EPL glades on animal populations. It is necessary to take into account the forming of intrazonal locations and real electromagnetic effects. The significant conclusions are found for birds, because they receive more irradiation. Also some biological peculiarities are important: the migratory species have a possibility to react immediately, according to the season, on the changing of biotopes. As for other animal groups, it is necessary to prolong the study of seasonal changes. For the invertebrates it must be performed the instrumental analysis of the differences of hydrotermic conditions of EPL glades and native biotopes.

The study of the host-guest association of Morin hydrate (MO) with b-cyclodextrin (b-CD) and C-hexylpyrogllol[4]arene (C-HPA) is reported in this paper. The iInclusion complexation of MO is studied by ultraviolet-visible, steady-state fluorescence, time-resolved fluorescence, 1H nuclear magnetic resonance (NMR), and two dimentional rotating-frame nuclear overhauser effect correlation (2D ROESY) spectroscopic techniques. The stoichiometry and the binding constant for the MO-b-CD complex are derived from the linearity of the Benesi-Hildebrand equation. The binding constant for the MO-C-HPA complex is calculated from the nonlinear curve fitting of fluorescence intensities. The effects of the acid strength on the absorption and fluorescence spectra of MO are studied in the absence and the presence of b-CD/C-HPA host molecules. The pKa values of the ground and the excited states are reported.
