Yusupov A.R., Kurbanismailova A.S., Alkhulaev K.G., Mamaev A.S., Yusupov Z.A. THE INFLUENCE OF ANTHROPOGENIC FACTORS ON THE CHEMICAL COMPOSITION OF LAKES IN ARID REGIONS OF DAGESTAN (ON THE EXAMPLE OF THE GREAT AND SMALL TURALI) // Arid ecosystems. 2021. V.27. № 4 (88). P. 118-122. | PDF
Anthropogenic impact on the ecosystems of arid areas leads to environmental pollution. Assessment of the state of nature of arid regions is the most important task in the context of scientific and technological progress.
When studying the current state of the Turaly lakes, as representatives of reservoirs of arid conditions, various research methods were used. This made it possible to draw a conclusion about the level of pollution of objects and to assess the ecological condition of reservoirs characteristic of natural complexes of arid conditions.

The article presents the materials of route, stationary soil, soil-ecological studies conducted in the high-mountain zone of Dagestan with the characteristic: a) the current features of the development of the soil cover; b) the ecological parameters of the soil cover and their changes under the influence of climate warming.
The variety of natural and economic conditions of the object of study caused a significant diversity of the soil cover. The distribution of the soil was greatly influenced by the height of the terrain, the exposure and the steepness of the slopes. Based on the soil erosion studies conducted in previous periods, it can be noted that improper land use and climate warming have led to radical changes in the composition of the soil cover in terms of determining indicators – soil erosion.
In recent years, the area of eroded land has doubled, the area with heavily eroded soils-by 1/3. This led to a decrease in the thickness of humus horizons in almost all soils to an average of 20 cm, and the loss of humus reserves in the soils amounted to 60% of the initial content. The presented analysis of the degradation of the soil cover and the established patterns of soil evolution on the slope lands of the highlands serve as a theoretical basis for the reproduction of soil fertility, the preservation of the ecological role of soil protection from erosion and other degradation processes.

The article provides material of monitoring and, analysis of the state and dynamics of erosion processes of agricultural land for the 16-year (2000-2016) period in the regions of the Stavropol territory. Currently, the spontaneous decline in agricultural production, primarily due to the farming culture, not so much contributes to the restoration of natural bioresources and biodiversity, but exacerbates the negative processes. An algorithm for assessing the state of the land has been proposed and the territorial distribution of 11 types of negative processes in the Stavropol region has been determined
