ANNOTATION

A 428-year tree-ring chronology for the Iskanderkul area, Sughd region, Republic of Tajikistan has been constructed and analyzed. Core samples were taken from Juniper hemispherical (J. semiglobosa) at an altitude of 2500-2700 meters above sea level. between the Gissar and Zeravshan ranges in the Sarytag region. Periods in the middle of the XX century and the beginning of the XXI century, which showed low increases can be associated with global climate change, in particular, an increase in temperature and a decrease in precipitation. This gives us a reason to assume that the chronology of this area can be used as a material for further reconstruction and forecasting of climatic parameters.
