Аннотация: This article presents a new tree-ring network of chronologies for Scotch pine and Siberian larch for the Republic of Khakassia. The key difference between this work and previous researchers who had previously constructed two chronology networks for the region under consideration is the establishment of trial plots in the rain shadow on elevated habitats (hill slopes and cuestas) on the western border of the Minusinsk basins. An analysis of the main statistical parameters of the new chronology network showed that, with the exception of first-order autocorrelation, there are no significant differences between the two tree species. Based on the results of cluster and correlation analyses, regional chronologies for Scotch pine and Siberian larch are obtained (by generalizing local tree-ring chronologies). Verification of the new network with previously published chronologies for the study area has shown that some of them contain obvious errors. The use of such chronologies without corrections for paleoclimatic reconstructions, dating of materials from historical buildings, etc., may lead to the distortion of research results. Of no less importance is the use of modern (digital) methods for measuring tree-ring parameters to improve the quality of chronologies. The fact that even the most distant chronologies (up to 230 km in a straight line) for different tree species are in good agreement with each other in the future will allow us to significantly expand the dendrochronological network by including new areas (primarily pine forests of the Republic of Tyva and Krasnoyarsk krai). In the future, this can significantly increase the existing potential of pine and larch forests in the south of Siberia for conducting a comprehensive analysis of the growth of woody vegetation in the forest steppe over the past millennium and performing paleoclimatic reconstructions.
