The spatial and species features of heavy metals (Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Mo, Pb) contents in higher aquatic plants of reservoirs and rivers within Belarus have been analyzed on monitoring data. The group of submerged plants are characterized by high ash content; and they accumulate large amounts of Ti, Mn, Cu, Zn, Zr, Pb. There are statistically signi ficant differences between the plants in ecological groups of reservoirs and rivers in terms of Mn, Cu, Pb contents in the tissues (elements with a 100 % frequency). According to the spatial analysis the reservoirs of the northern geochemical province account for 71 % of the Mn anomalies and 80 % of the Cu anomalies, including the Braslav region – 46 % of the Mn anomalies and 59 % of Cu. Mn, Cu, Pb maximum concentrations are characteristics of submerged macrophytes such lakes as Snudy, Losvido, Maloye Beloye, Beloye (Luninets District), Beloe (Surmino), Svityaz. Among submerged macrophytes within lakes the abnormal accumulation of Mn has been noted for Charophyta (61 % of cases), Myriophyllum and Ceratophyllum, Cu – Charophyta, Isoetes and Lobelia dortmanna, Pb – Isoetes, Charophyta and Potamogeton. The macrophytes within rivers are characterized by the higher ash content and the average content of Mn, Cu and Pb in comparison with the lakes plants. Areas with identified Cu and Pb anomalies in the submerged plants are confined to the central geochemical province of Belarus (the Svisloch river accounts for 67 % of anomalous values of Cu and 33 % of Pb). Anomalous values of Cu have been fixed in the tissues of the Ceratophyllum and Potamogeton, Pb – mostly in Potamogeton. The cluster analysis has distinguished a group of plant species as a part of the following genera: Potamogeton, Myriophyllum, Elodea, Ceratophyllum and Sparganium. The group is characterized by elevated contents of Ti, V, Cr, Mn, Ni, Cu, Zn, Zr, Pb and recommended as indicators of polluting water objects with heavy metals.

The article presents the experience of using the landscape approach in optimizing the land use system of the alpine-subalpine highlands of Chornohora in the borders of the Transcarpathian region, the quality of the pasturage. On the basis of the features of the landscape organization of the mountainous territory and the properties of the integral geomapplexes of Chornohora, on the example of the key-site Sheshul – Petros, as well as regularities of the distribution of negative natural processes, the main centers and scale of the influence of the pasturage objects on the specific natural territorial complexes of the level of the tract were determined. On the landscape basis there are conditionally distinguished highland natural complexes from artificially developed pasture lands of forest middle level tier. The largest field pasturing type in the vicinity of the key area of Sheshul – Petros, the features of their placement and functioning, as well as the extent of attracting highland tracts, which are also used in the economy as pasture land in our research. The analysis of the morphological structure of the highlands made it possible to establish regularities of the organization of natural complexes, which express the properties and ecological state of the polonina pasture lands, and to develop recommendations for optimization of the pasturage as the main land useage of the highlands of Chornohora.

Analysis of lithological and genetic features quaternary deposits within the influence zone of industrial objects continues to be an urgent task of modern geology and geoecology. The article presents the results of studies of the lithologic features of quaternary deposits of the first from the surface of the low permeable layer underlying the ground aquifer within the sanitary protection zone of the Gomel chemical plant (GCP). In its structure, genetic types, groups of facies and facial varieties were identified. Large-scale (1 : 25 000) mapping of the established facies of quaternary deposits has been carried out. The present-day appearance of the formed natural and technogenic landscape has been studied. It has been established technolithomorphological changes of the geological and geomorphological basis of natural landscapes took place in the production zone of the plant. Facies of technogenic genesis has been identified.

Integrated data of the structure and mineralogical composition of the marking tuff horizon in the Upper-Devonian bed of the North-Shestovich synclinal zone are presented in this paper. Dependence of the tuff bed structure on the volcanic activity stage is revealed. Find out that the prevailing mineral of tuff is the structure-ordered illite 1M. Marked tuff horizon is situated inside the Upper-Devonian salt bed within Petrikov synclinal zone and comes up into the overlaying clay-marl formation of the surrounding geological beds.

The requirements of complex subsoil use are increasing in the Pripyat potash-bearing basin: potash ore of new technologic types, with lower contents of useful components, increased concentrations of harmful impurities. Using all complex of quality indicators assessment of natural types of potash ore is undoubtedly prioritized by characteristic of potash deposits. The study of structural and textural features and composition of potash deposits has been given attention since the time of discover of the Starobin deposit. Systematic study of salt rock petrology has been started after the discovery of the Starobin deposit. Until now in the petrology, there is no recognized rational genetic classification of the structures of salt rocks being potash (potassium-magnesium) ore. The name of certain structure is based on the secondary features that are brightly expressed, color or similarity with different objects. The aim of the present work is an element recognition of the primary sedimentary features of rocks, systematization of primary and secondary characteristics and their typification according to petrochemical parameters. In the article the main microfabric types of potash ore that are typical for the deposits of red-colored and mottled hypersaline association of the Pripyat basin.

The article is devoted to the analysis of economic-geographical and socio-economic differences of the regions of the Republic of Belarus in order to improve the administrative and territorial division (ATD). The decisive role of the Belarusian scientific school of economic geography in developing of the principles of the ATD of Belarus at various periods of development is shown. The historical stages of formation, advantages and disadvantages of the current system of the ATD of the Republic of Belarus are revealed. The positive and negative international experience of conducting of administrative and territorial transformations is systematized. The significant disproportions in the resource, demographic and economic potential of the regions of Belarus and their various contributions to the social and economic development of the state are determined. Based on the centro-peripheral principle, a scheme of the regions of Belarus by the level of socio-economic development has been developed, which indicates significant changes in the development of regional economic complexes that have occurred over the past decades. About 20 % administrative districts are characterized by the properties of the center or semi-center, which have the ability to perform the functions of regional centers in the new ATD. More than 30 % administrative areas are peripheral in terms of socio-economic development. The obtained results are the basis to the need to improve the ATD of the Republic of Belarus.
