Анотация: Trees can give clear visions of what parameters influence in this or that period of its growth. Due to lack of the influencing of climatic variables on tree growth in this area, therefore we are faced with the task of what climatic factors affect growth in different periods of development, how different soil moisture layers are related to other parameters and its relationship with the tree. Tree-ring width chronology of Populus euphratica was investigated based on dendrochronological standards on the Irtysh river floodplain, Altai Prefecture at an altitude of 500 m a.s.l. and climatic factors influencing the tree-ring width were examined using a Pearson’s correlation coefficients. Six parameters of monthly climatic data [mean temperature, total of precipitation, relative humidity, base flow, snow water equivalent and soil moisture <>] were used for the analysis. Ring width related to precipitation and snow water equivalent from the end late growing season prior November until early growing is March, where the April temperature affects negatively, thereby increasing evaporation and including the effect of relative humidity. Soil moisture effected to tree-ring width from prior November to this June, while base flow influence current April-September. Such spectral high frequency cycles were identified at 16.3, 12.5, 8.1, 2.7, 2.6, 2.4 and 2.1-years, which suggest possible linkages with huge scale ocean-atmosphereland circulation system and an influence of solar activity. Our results suggest that all the connection have possess time to impact, so Populus euphratica has a sufficient potential to shed light on climatic factor.
