One of the main problems at engineering-geological
researches is the choice of the most suitable territory
for construction of designed projects and
constructions. The most dangerous threat to the
economy and the security of the Krasnodar region are
geohazards. The article provides an expert evaluation
of engineering-geological conditions of the territory,
the map-scheme of evaluation of engineeringgeological
zoning of the region. The characteristic is
given to the engineering-geological taxons allocated
on degree of usefulness of conditions
The chemical composition of neogen-quaternary, paleogene, cretaceous and paleozoic aquifer systems in the Ob-Tomskoye interfluves area is presented in the article. The water saturation with respect to secondary minerals is described. Authors show that the waters of all studied aquifer systems are saturated with respect to montmorillonites and calcite in a less degree. The geochemical water types are identified and their distribution is described
The article is devoted to the study of the spatial
distribution of air temperature, precipitation and their
ratio in the form of moisturizing factor of the Mayma
river basin. Calculations of the vertical and horizontal
gradients are hold. Cartographic models of the
distribution basic climatic indices are also constructed
The article presents the experience of engineeringgeological
zoning to establish patterns of spatial
variability of the components of engineeringgeological
conditions. In the ArcGIS environment was
created a set of electron-digital maps, taking into
account the influence of adverse geological processes
and landforms for the design, construction and
operation of linear engineering structures.
The article considers the issue of increasing the accuracy of filling geodetic networks of quadrangles with measured by the parties by increasing the number of conditional equations. We have considered the three variants of placement of additionally measured diagonals of the squares. The results improve the
accuracy in the determination of coordinates of points within the network, due to these additional measured elements
Increasing of tea production in the foothills of
Adygea should be based on potential soil properties
suitable for tea plant. The goal was achieved using
modern methods of soil evaluation of tea plantations.
The evaluation criteria were the following
agrochemical and agro indicators: soil acidity (pH
KCl); hydrolytic acidity; the sum of exchangeable
bases; bases saturation; granulometric composition. It
was found that the soil under tea plantation in
Adygeya classifies as brown forest poorly
unsaturated with the level of potential fertility rated
as satisfactory (bonitet rating 40-60). However, the
low supply of nutrients in the layer 0-40 cm:
phosphorus (19,04 ± 2,42 mg / 100 g soil), potassium
(17,70 ± 1,60 mg / 100 g soil) and a sufficiently high
degree of saturation of soil bases in the layer of 50-
100 cm (67,10 ± 11,67%) in combination with a soil
moisture deficit determine their low productivity of
16,0 ± 5,0 kg / ha, whereas their potential
productivity of 30-50 t / ha. The development of
scientifically grounded, targeted ameliorative and
agro-technical measures (irrigation, nutrition systems
using physiologically acidic forms of nitrogen and
potash fertilizers that reduce the degree of saturation
of the soil bases) will help to increase the effective
soil fertility and allow the tea plants reach its
biological potential and achieve predicted
productivity in Adygea region
Many scientists suppose that rural tourism as a kind of
tourism industry in Russia has not got long history.
But we can see its manifestations at different stages of
tourism development, which are described in the given
article. In different historical periods, rural tourism had
its own forms, modifications and kinds of activity.
That is why we can say that agrarian tourism took
place in pre-Soviet and Soviet periods too. Besides, we
still have troubles with theoretic aspects of rural
tourism. Today science society invents a determination
of rural (agrarian) tourism, creates classifications of
this and so forth. Nowadays rural tourism is a
polyfunctional phenomenon. That is why we should
explore it in more details. The Krasnodar region has a
lot of recourses which allows us to develop many kinds of tourism, including agrarian on its territory.
Existing legal environment creates attractive
investment climate and helps to develop rural tourism
in the Krasnodar region successfully
The structural and functional properties of humic acids of different types of poorly studied soils of the Krasnodar Region: ordinary black soil or chernozem (carbonated), meadowish chernozem and gray forest soils are investigated. We define the type of humus of the soil samples studied as fulvate-humate. Using traditional indicators of humus soil conditions the regularities of soil and ecological processes involving organic matter in soils under natural and anthropogenically factorial changes in the monitoring sites are revealed. The relationship of the optical properties of humic acids with the intensity of the processes of transformation of humic substances by increasing the depth of the soil sample is shown. By NMR spectroscopy, IR spectroscopy, and spectrophotometry in the visible spectrum differences and similarities in the structure of macromolecules of humic acids in soil samples. In terms of soil contamination with oil in a field experiment, on the monitoring site we have set a trend towards to redistribution in the ratio of functional groups of humic acid macromolecules: the proportion of aliphatic fragments increases. We have revealed an increase in the share of the mobile fraction of humic substances in terms of oil pollution. The article has the most suitable justification for these processes. The results can be used for prediction the environmental state of the soil under anthropogenic pollution
Even with the modern development of geodetic
techniques to abandon traditional ways a
condensation of planned networks is not possible.
Therefore, the article describes the case of
determination of coordinates of points using
backwards the angular notch and the accuracy of
their determination. In the classical methods of
solving the backwards the angular notch are
calculated coefficients, and get the coordinates of the
designated point. The authors propose to use
auxiliary angles that will reduce the amount of
calculation. In addition, the article gives examples of
solutions to well-known formulas of Gauss and
through the calculation of direct geodetic purpose
The article examines the development of a planned
study on the clearings and roads in built-up and
forested areas, as well as for building networks. Most
often, it is recommended to use the method without
diagonal quadrangles, where in each figure measured
all four corners and the length of one of the parties,
and in the first and last rectangles – four corners and
two sides. The length of the other sides is obtained by
computing, previously having leveraged the angles in
the quadrilaterals. The disadvantage of this method is
the adjustment of such circuits in a simplified manner,
namely: the distribution of residuals arising in the
augmentation of coordinates fx and fy equally to all
augmentation. The article proposes formulas of Gauss
for direct angular notches to make the conditional
equation of directional angles, deciding which method
of least squares, find the amendments to the measured
directional angles. Introducing these amendments, I
get the coordinates of the desired points of successive
angular intersection. As it may be seen from
preliminary calculations, the errors resulting from the
use of differential corrections in the coordinates are
very small and may not have a significant influence on
the measurement result
