LANDSCAPE AND LIMNOLOGICAL RESEARCH OF LAKE SYSTEMS OF THE PLAIN AREAS OF THE NORTHEASTERN BORDERLANDS OF THE REPUBLIC OF KAZAKHSTAN AND ASSESSMENT OF THEIR RECREATIONAL CAPACITY

Abstract

The article is concerned with landscape and limnological research of lake systems in the plain areas of the Republic of Kazakhstan. The results obtained present field expeditionary, landscape and limnological research, primarily of the plain areas of the northeastern borderlands of the Republic of Kazakhstan. A genetical classification of lake basins in key areas, as a single natural complex, based on the main features of environmental conditions in the research area is given. The hydrological and hydrochemical data of lake systems (temperature, transparency and color of water, pH value, content of oxygen dissolved in water and BOD5 of biochemical oxygen demand) are determined. An assessment of the recreational capacity of lakes in the region is given. The created electronic geodatabase is open to replenish it with miscellaneous information (from paleogeographic data to modern results of environmental monitoring) and can serve as the basis for creating a multi-purpose cadastre of reservoirs, as well as for justifying balanced nature resource management schemes in the areas covered with lakes.
