   <abstract xml:lang="ru">
    <p>Рассмотрен подход к реконструкции продуктивности пелагических экосистем, основанный на численном моделировании фракционирования изотопов углерода. При моделировании использованы данные о содержании углекислоты в атмосфере, температуре воды, а также об изотопном составе углерода карбонатов и конодонтовых элементов. Предложенная модель опробована на материале из верхнего девона — нижнего карбона Cеверного Приуралья (разрезы карбонатной платформы и склона внутришельфовой впадины). Данная модель позволяет реконструировать продуктивность палеозойских пелагических экосистем и ее динамику по ограниченному набору исходных данных. При этом результаты моделирования представляются скорее качественными, чем количественными. Корректность модели проконтролирована результатами определения изотопного состава органического вещества.</p>

    <p>The article considers an approach to the reconstruction of the bioproductivity of Palaeozoic pelagic ecosystems based on the numeric modelling of the carbon isotope fractionation. The model uses information on the carbon dioxide content in atmosphere, water temperature, and carbon isotopic composition of carbonates and conodont elements. The developed model is tested on the material from the Upper Devonian — Lower Carboniferous of the northern Cis-Urals (successions of carbonate platform and slope of intrashelf depression). It allows reconstructing of the primary productivity of the Palaeozoic pelagic ecosystems and their dynamics on the basis of limited data. The results of the modelling are considered as rather qualitative than quantitative. The carbon isotope composition of total organic carbon was used for controlling the quality of the model.</p>
