The impact of changes in climatic factors of the Aktumsuk region on the formations of Medicageta sativa

The article presents a brief analysis of 20-year changes in climatic parameters the Aktumsuk region Eastern Cliff Ustyurt and their impact on species composition Medicageta sativa formation. From obtained daily indicators 2 sources (NASA POWER meteorological station), long-term trends average, average maximum minimum air temperatures, as well annual precipitation have been established. Data from 2000-2020 were taken for analysis. warm cold seasons year established, which affected amplitude parameters. Basically, decrease temperature occurs half-year (November-December, January-March), explains increase during these periods. most significant warming territory was noted (April, June, July August). data comparing temperatures above-mentioned period indicates that climate is sharply continental, here we can observe sharp regime direction warming, could lead to transformation appearance xerophytes this type vegetation recent years provides information about xerophytization flora due an drought Cliff. Climate aridization, reduction number mesophytes composition, projective coverage, halophytes communities may indicate change.
