Геоморфологические формации горного ряда связаны с неотектоническими блоками, испытавшими воздымание в позднем кайнозое. Проанализированы следующие морфометрические показатели: абсолютная высота, глубина и густота расчленения, средние углы наклона склонов, степень сохранности поверхности выравнивания (пенеплена), развитой в пределах рассматриваемой территории до начала неотектонической активизации. Охарактеризованы критерии различия геоморфологических формаций горного ряда по морфометрическим показателям. Установлено, что густота расчленения не различается между разными типами формаций, а остальные показатели существенно разнятся. Выявленное сходство горизонтальной расчлененности у разных формаций свидетельствует о том, что гидросеть закладывается на ранних этапах горообразования и далее развивается унаследованно.</p></abstract><trans-abstract xml:lang="en"><p>This work presents an analysis of morphometric parameters for low-mountain, mid-mountain, and high-mountain geomorphological formations of the Great Altai, Western Sayan, and Eastern Sayan. The geomorphological formations of the mountain belt are associated with neotectonic blocks that experienced the Late Cenozoic uplift. Anaysis has been made of the morphometric parameters such as absolute elevations, depth and density of dissection, average slope angles, and the degree of preservation of the planation surface (peneplain) formed within the study area prior to the onset of neotectonic activation. The characterization has been performed of criteria for morphometric differentiation between geomorphological formations of the mountain belt. It has been found that the density of dissection does not differ between the different types of formations, whereas all other parameters show a significant difference. The identified similarity in horizontal dissection across different formations suggests that the initiation of the hydrographic network was the early orogenic stages, after which it had continued to develop inheritedly.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Алтае-Саянская горная область</kwd><kwd>морфометрические показатели рельефа</kwd><kwd>геоморфологические формации</kwd><kwd>неотектоника</kwd><kwd>геоинформационные технологии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Altai-Sayan Mountains</kwd><kwd>morphometric relief parameters</kwd><kwd>geomorphological formations</kwd><kwd>neotectonics</kwd><kwd>geoinformation technologies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено в рамках госзадания ИГМ СО РАН (проекты № FWZN-2026-0004, FWZN-2026-0011).</funding-statement><funding-statement xml:lang="en">The study was carried out on the state assignment of the Sobolev Institute of Geology and Mineralogy SB RAS (projects No. FWZN-2026-0004, FWZN-2026-0011).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Drăguţ L., Eisank C., 2012.
