SOIL COVER TRANSFORMATION OF THE TEREK-KUMA LOWLAND (DAGHESTAN SECTOR) UNDER CLIMATIC CHANGES CONDITIONS
GASANOVA Zarema Ulubiyevna
The intermediate position of the Terek-Kuma lowland, the close connection of groundwater with Caspian Sea level dynamics contributes to the transformation of the soil cover depending on the direction of groundwater dynamics. During nearly hundred years, the composition of the soil cover of the lowlands at the typical level remained constant: sands, chestnut soils, solonchaks, solonetz-solonchaks, alluvial, meadow, marshes. The share participation of soils and soil diversity changed. Minimal diversity occurred during the period with a low groundwater level. The highest participation was noted for chestnut soils. Meadow soils have the lowest participation, which is typical for transition zones - the smallest areas in the composition of the soil cover. Along with the analysis of survey maps, the transitional nature of meadow soils was confirmed by studies of the soil cover on a detailed scale: the largest range of values fell on meadow soils, which indicates the high dynamics of salt solutions in the soil cover.
