Main features of Maria Alfredovna Glazovskaya’s work

  • Glazovskaya M.A. Geochemical barriers in plain soils, their typology, functional characteristics and environmental importance

The article summarizes and analyses information about geochemical barriers accumulated in numerous landscape-geochemical studies. An attempt is made to elaborate an integrated functional-genetic classification of barriers according to various criteria, i.e. genetic, functional, temporal, topological etc. The importance of genetic approach to the investigation of geochemical barriers for solving environmental problems is underlined.

In elaboration of M.A.Glazovskaya’s ideas

  • Kasimov N.S., Vlasov D.V. Technophilia of chemical elements in the beginning of the 21st century
The notion of “technophilia” introduced by A.I.Perelman characterizes correlation between the intensity of use of chemical elements by the mankind and their mean concentrations in the lithosphere. Technophilia of elements in the first decade of the 21st century is calculated and scenarios of its change towards the end of the century are suggested. New parameter, i.e. regional technophilia, is proposed to facilitate classification of the world countries in terms of the intensity of technogenesis.
  • Bogdanova M.D., Gavrilova I.P., Gerasimova M.I. Elementary landscapes as objects of landscape-geochemical mapping
Conceptual and spatial interrelationships of “elementary landscape”, “facies” and “biogeocenosis” notions are discussed in relation to problems of the large-scale landscape-geochemical mapping. Taxonomic levels of landscape components, i.e. attributive elements, are analyzed. Taxonomic diversity of characteristics of the components of elementary landscape was revealed. While mapping elementary landscapes characteristics which control migration processes are taken into account for each component despite of its taxonomic level.
  • Avessalomova I.A., Diakonov K.N., Savenko A.V. Geochemical traps on the way of water migration of anionic elements (case study of taiga landscapes of the East-European Plain)
Distribution of anionic elements (Cl, F, Si, P) in the water of taiga landscapes of the East-European Plain was analyzed. Factors of lateral differentiation of their mobile forms and contrasts of their localization in catenas were revealed. The role of anthropogenic factors which change water migration of biogenic elements and the preconditions of eutrophication of water bodies are discussed.

Theory and methodology

  • Rychagov G.I., Sudakova N.G., Antonov S.I. About ice age stratigraphy and paleogeography of the central part of the East-European Plain
Actual issues of ice age stratigraphy and paleogeography of the central part of the East-European Plain are discussed. Unsatisfactory solution of the problem is mainly due to the underrating of the importance of integrated physical-geographical approach. The authors prove their standpoint by the results of long-term field investigations and laboratory studies in the sphere under discussion. Debatable questions which require further investigation are discussed.
  • Alexeevsky N.I., Murakaev R.R. Integration of elements of temporary and perennial watercourses within a water catchment area
An approach to the elaboration of an integral scheme of formalization of the elements of a cascade system of integrated temporary and perennial watercourses is discussed. It is based on the concept of “conventional orders” of watercourses which describe correlation between the size of watercourse, the area of its catchment and the average maximum of water discharge from the area under current climatic and morphographic conditions. Unlike the already elaborated schemes of structural formalization of watercourses the suggested approach doesn’t require denotation of an elementary watercourse. Thus the scheme could cover the whole system of temporary and perennial watercourses within a water catchment area by assigning conventional orders to indefinitely small watercourses. The strength of the concept is illustrated by its application for a number of water catchment areas within the central regions of the European part of Russia.
  • Korotayev V.N. Comparative analysis of the Late Holocene and present-day river deltas of Northern Eurasia
The areas of the Late Holocene and present-day river deltas were determined using the geological and geomorphologic data, topographic maps and space imagery. An attempt to evaluate the intensity of delta formation was made and the prognosis of the evolution of river mouth systems is suggested.

Methods of geographical studies

  • Bozhilina E.A., Sorokina V.N. Principles of geographical cartography in modern climatology

Principles of geographical cartography and their importance at the present-day stage of geoinformational mapping development are discussed. The results of automated and geographical interpolation of data in the process of mapping air temperatures and annual precipitation for the territory of the Irkutsk oblast are presented.

  • Kravtsova V.I. Spatial structure of tundra-taiga ecotone within the Putorana Plateau (basing on very high-resolution space imagery)

Interpretation keys and specific features of the structure of the Putorana Plateau forest and forest-tundra vegetation image were determined using space imagery of very high resolution and field observation data. The vegetation map at the scale of 1:5000 was compiled which shows very complex spatial structure of the tundra-taiga ecotone.

Regional studies

     
  • Dubinin E.P., Kokhan A.V., Grokholsky A.L., Rosova A.V. Specific features of relief morphology and structure formation in the rift zone of the Reykjanes Ridge

Specific features of structure formation and segmentation of the super-slow spreading Reykjanes Ridge are described. The large-scale axial morphology changes with the growing distance from the Icelandic mantle plume, i.e. from the large upland to the mid ridge and the rift valley. Morphostructural schemes for the sites with different morphology made it possible to reveal the character of changes in the axial morphostructural segmentation of the rift zone. Experimental modeling proved that the leading factors of structure formation of the Reykjanes Ridge are the depth of the axial lithosphere, width of the heating area of the rift zone and the oblique position of the ridge relative to the direction of spreading.

  • Yemelianova L.G., Levik L.Yu. Geography of mammal biodiversity in the central part of European taiga
Spatial organization of mammal biodiversity in the central part of European taiga within the Arkhangelsk oblast is described. Data on local faunas and mammal population of the territory are summarized. Comparison of local biotas and cartographic method of studying the structure of species range using the numbers criterion made it possible to analyze taxonomic and typological structure of mammal diversity, both indigenous (reconstructed) and anthropogenically transformed.
