High-closed broad-leaved forests are found mainly on the northern and western slopes, whereas scattered and scrub broad-leaved forests, bush, semi-bush and grass communities are found in the south and east. The soil-vegetation cover shows the technogenic impact evidence like on other islands previously belonging to the military department. The landscape structure is composed of 16 morphological units. The total territory is a mountain landscape class, with about 82% of the area belonging to a low-mountain landscape subclass, and 12.35%, to a coastal subclass. Beach accumulative landscape developed on sandy-pebble coastal sediments without soil-vegetation cover is located in the north. Uncontrolled recreational activity has become recently the major factor of anthropogenic transformation of natural complexes. High number of visitors and campsite activity increase the fire danger. Ground fires disturb natural ecosystem functioning. The vegetation, lichens and soils bear the evidence of fire impact. Intense mechanical impact on the soil-vegetation cover occurs in the campsite areas. Because of low depth and high skeletal soil, the bulk of island land is prone to erosion. Trampling leads to active sheet soil erosion and destruction of grass-bush layers. The total content of heavy metals in accumulative-humus layers makes up a small proportion of the approximate permissible concentration. Recreational activity, in particular, burning of solid waste explains high concentration of heavy metals in the west. Copper concentration increases by an order of magnitude there in comparison with ones from the other island parts. The copper concentration comes close to the approximate permissible concentration or may outnumber it, considering an analytical error. Zinc concentration outnumbers the approximate permissible concentration without including analytical error. \u0000Intense anthropogenic impact disturbs the spatial landscape structure and changes material-energy flows resulting in decreasing landscape diversity. Though Shkota Island geosystems have experienced high anthropogenic influence since the beginning of the XXth century, today we observe reliable restoration of destroyed ecosystems. These areas are being actively covered with grass-bush communities dominating by Lespedeza bicolor and Artemisia gmelini, which boosts humification and humus accumulation. Saplings of broad-leaved trees spring there. But periodic ground fires make stable forest restoration difficult.","PeriodicalId":309934,"journal":{"name":"Геоэкология. Инженерная геология.

A significant variation is shown in the concentrations of dissolved substances in river water due to large differences in the composition of underlying rocks, groundwater and wastewater, as well as water of worn-out water supply and sanitation systems. The hydrocarbonate-calcium composition of water, the lowest pH and mineralization values, the phosphate concentrations, as well as the dominance of sulfate ion over chloride and nitrate nitrogen’s dominance over ammonium in the river water in the protected areas were identified. The higher content of dissolved substances and the bicarbonate-calcium (sometimes magnesium) composition of water are typical for the rivers in the outskirts of the city, fed mainly by groundwater in alluvial deposits. Hydrocarbonate-sodium (rarely ammonium) composition of water, maximum concentrations of major ions, contamination with phosphates, ammonium nitrogen, petroleum products and surfactants, absence of nitrite and nitrate nitrogen in anaerobic conditions were noted in the river water at the outskirts of the city, which are fed by wastewater. The hydrocarbonate-calcium composition of water, a decrease in the elevated concentrations of major ions during the winter season, pollution with ammonium and nitrite nitrogen, phosphates and oil products of water in the rivers of the central part of the city fed by groundwater and water of worn-out water supply and water disposal systems were established.","PeriodicalId":309934,"journal":{"name":"Геоэкология.

We paid particular attention to the karst, which was widespread in the area and its relation with agricultural landscapes. We made mathematical modelling of both elementary agricultural landscape spatial pattern and the corresponding rural settlement pattern. A feature of the proposed modeling is its emphasis on the relationship between the natural landscape and agricultural landscape. The mathematical morphology of landscape (method proposed by A. Victorov) and, in particular, the karst system model is the base of modeling. This model is first used for the analysis of cultural (anthropogenic) rather than natural landscapes.","PeriodicalId":309934,"journal":{"name":"Геоэкология. Инженерная геология. Гидрогеология.

In 2012, seventeen years after the termination of Na-PCP use as wood-preservation agent (biocide), the presence of PCP and HCB classified as persistent organic pollutants was determined in soils of the industrial site of the shutdown timber mill. The tendencies towards a decrease in the residual amounts of toxic organochlorine components of Na-PCP were revealed. At the same time, soil pollution with HCB remained at a high levels, several times higher than the health-based exposure limit (approximate permissible concentration, Rospotrebnadzor, Russia), while the concentrations of PCP for the most part already complied to the approved quantitative national regulations (human health soil quality guideline, CCME, Canada; regional screening level, US EPA). It has been shown that residual amounts of biocide impurity component (HCB) in soils repeatedly (by a factor of 4–47) exceed the main component (PCP) concentrations, determining the role of HCB as the high priority soil pollutant at present. The presence of PCP and HCB in the soils of the residential settlement area suggests that recent soils of the industrial site of the timber mill present an active secondary source of persistent organic pollutants to the environment, with the threat of its distribution as a result of local, regional and global transport in the long-term future.","PeriodicalId":309934,"journal":{"name":"Геоэкология.

Fisher, Н К Фишер","doi":"10.31857/S0869-78092019321-31","DOIUrl":"https://doi.org/10.31857/S0869-78092019321-31","url":null,"abstract":"According to the thermodynamic ladder, microorganisms in groundwater use electron acceptors consistently – for transformation of pollution from the pollution plume edge to its core. However, some researchers come to the conclusion that only methanogenic biotransformation of pollution or reduction of Fe(III) and Mn(IV) from the solid phase can occur in the plume, and due to the kinetic factor microorganisms use electron acceptors from the aqueous phase (O2, NO3- и SO42-) only on the edge of the pollution plume. The purpose of the research was to determine whether microorganisms use Fe(III) and Mn(IV) as acceptors of electrons for hydrocarbons transformation in groundwater in the northern part of the Middle Heilongjiang-Amur River basin aquifer. In the study area, both lenses of petroleum-hydrocarbons (non-aqueous phase liquids) on the surface of groundwater (up to 2.5 m) and high concentrations of dissolved hydrocarbons (up to 1000 mg/l) are noted. Microbiological processes were assessed in situ by the method of geochemical indicators. The most active biogeochemical processes occurred during the spring-summer rise of groundwater level. The seasonal increasing of level led to the entry of Fe(III) and Mn(IV) into the pollution plume and activation of the microbiological processes of its reduction. Microorganisms mostly use electron acceptors from the solid phase – Fe(III) and Mn(IV), but not NO3, SO42 from the aqueous phase. This is confirmed by the close correlation of HCO3- formation and that of Fe(II) and Mn(II) in groundwater (r2 up to 0.93). This says that for the groundwater self-purification the kinetic factor rather than thermodynamic one is decisive; and microorganisms use electron acceptors that are currently available. As a result of microbiological pollution destruction, the content of Fe(II) in groundwater increased up to 100 mg/l, Mn (II) – up to 16 mg/l, which exceeds the natural background 4 and 8 times, respectively. This was also because the regional geochemical background of the study area (Amur River basin) forms Fe and Mn.","PeriodicalId":309934,"journal":{"name":"Геоэкология. Инженерная геология.

More than 99% of the sum of all the heavy metal mass with concentration above 0,1 mcg/dm3 is defined by the presence of fourteen metals ranged as following: Fe>>Mn>>Sr>Ba>Zn>Rb>Cu>Co>Ni>V>Ce>Zr>Pb>La. Groups of such metals as manganese and strontium, nickel and cobalt, lead, zinc and copper, vanadium and zirconium, cerium and lanthanum form the concentration сlusters. In comparison to large and average rivers, water samples from small rivers contain higher concentrations of iron and manganese, and lower concentrations of zinc. The Fe and Mn content may vary depending on such characteristics as water color index and water turbidity. The significant exceedance of MACf of Fe and Mn is observed everywhere. The excess of zinc, caused by natural factors is occasionally fixed.
