Полнота и достоверность палеогеографических реконструкций определяется выбранными объектами исследования, среди которых палеопочвы археологических памятников (курганов) степной зоны европейской части России, а также лёссово-почвенные толщи Приазовья, содержащие серии ископаемых почв плейстоцена (последние 800 тыс. лет). Для проведения количественных реконструкций параметров состояния окружающей среды использованы три независимых метода: 1) магнитный метод (магнитная восприимчивость почв), связывающий почвенную “магнитную запись” с предшествующими условиях окружающей среды степей и позволяющий получать количественные характеристики климата (атмосферные осадки) в плейстоцене и голоцене; 2) геохимический, базирующийся на эмпирических зависимостях геохимических коэффициентов выветривания, связывающих изменения валового химического состава почвенной массы и еe элементов с климатическими факторами, а также комплекс минералогических исследований; 3) методы изотопной геохимии, изотопный состав углерода, позволяющие получать информацию о климатическом режиме территории, реконструировать некоторые параметры климатических систем. На основании полученной совокупности магнитных, геохимических, изотопных параметров почв и пород предложен оптимальный вариант набора показателей для палеоклиматических реконструкций и промоделированы климатические условия (палеотемпература, палеоосадки, аридность), характерные для природной среды степей Евразии в голоцене и плейстоцене.</p></abstract><trans-abstract xml:lang="en"><p>Reconstructions of the dynamics of soil formation conditions’ climatic parameters in Quaternary in the south of the East European Plain are performed. Reconstructions are based on the study of paleosols as indicators of biosphere evolution on the scale of geological and historical time. The completeness and reliability of paleogeographic reconstructions is determined by the selected research objects, including the paleosols of archaeological sites (kurgans) of the steppe zone of the European part of Russia, as well as loess-soil sections of the Azov region, containing a series of Pleistocene paleosols (the last 800 thousand years). Three independent methods were used to perform quantitative reconstructions of paleoenvironment: 1) magnetic method (magnetic susceptibility of soils) linking the soil “magnetic record” with the previous environmental conditions of the steppes and allowing to obtain quantitative climate characteristics (precipitation, aridity) in the Pleistocene and Holocene; 2) geochemical method based on empirical dependencies of geochemical coefficients of weathering, linking changes in the bulk chemical composition of soil mass and its elements with climate factors, as well as a complex of mineralogical studies; 3) methods of isotopic geochemistry, the isotopic composition of carbon, allowing us to obtain information about the climate regime of the territory, reconstruct some parameters of climate systems. Based on the obtained set of magnetic, geochemical, and isotopic parameters of soils and rocks, the optimal indicators’ set for paleoclimatic reconstructions is proposed. The climatic conditions (paleotemperature, paleoprecipitation, and aridity) of the natural environment of the Eurasian steppes in the Holocene and Pleistocene were modeled.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эволюция почв</kwd><kwd>палеопедосфера</kwd><kwd>глобальные изменения климата</kwd><kwd>магнитные свойства почв</kwd><kwd>геохимия</kwd><kwd>почвенная минералогия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>evolution of soils</kwd><kwd>paleopedosphere</kwd><kwd>global climate change</kwd><kwd>soil magnetic properties</kwd><kwd>geochemistry</kwd><kwd>soil mineralogy</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена при поддержке Российского фонда фундаментальных исследований (грант № 1929-05178; 19-54-45008).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The work was supported by the Russian Foundation for Basic Research (grant nos. 19-29-05178; 19-54-45008).</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">Алексеев А.О., Алексеева Т.В.
