Abstract
The article highlights the significant contribution of V.A. Snytko to the study of matter movement by aeolian processes in the steppe and forest-steppe geosystems of Siberia. The scientist paid much attention to the Baikal region. Based on the analysis of the hydrothermal environment and special experiments, he established that the intensity of aeolian migration of matter is a reflection of the climatic situation, and an indicator of the state of landscapes and the degree of their technogenic transformation. In each studied landscape, V.A. Snytko took into consideration the wind regime prevailing in areas of active deflation and accumulation of aeolian deposits. Together with Polish researchers, he carried out a typification of aeolian tracts. The established morphological and dynamic features of modern aeolian migration of matter are important for the purposes of geographical forecasting. The great role of aeolian processes in the spatial differentiation of matter is noted. It is shown that anthropogenic use of the sandy shores of Lake Baikal led to their degradation and disrupted the course of aeolian processes. As a result of many years of research, the features of the transformation of the functioning of aeolian geosystems have been identified. It has been noted that all Baikal geosystems require careful handling. The results of the research are reported in numerous articles, collections and monographs.
