Статья посвящена решению важной проблемы, возникающей при оценке экологического состояния техногенных ландшафтов, определению содержания углерода педогенных органических веществ (гумуса) в обогащенных углистыми частицами почвах. Авторами предложен подход, позволяющий определять литогенный потенциал гумусонакопления как максимально возможное содержание гумуса в почвах. Выявлены зональные закономерности формирования литогенной основы гумусонакопления в зависимости от выраженности аридности или гумидности климата. This paper is devoted to the solution of a problem arising at estimating the ecologic condition of man-caused landscapes: determination of paedogene organic substance (humus) carbon content in soils enriched with coal partitions. Basing on a thesis that almost all paedogene organic substance in soils is connected with the mineral part, the authors offer an approach that allows determining the lythogene potential of humus accumulating as the maximum possible humus content. The goal of research is identify the zonal regularity of paedogene organic substance accumulating in soils of coal-mine dumps of Siberia by estimating lythogene potential of humus accumulating. Young soils of man-caused landscapes formed on the surface of coal-mine dumps and widely presented in different regions of the Siberian Federal District were the objects of research. Soils of autonomic positions of man-caused landscapes located in humid, sub-humid (mountain-taiga and forest-steppe zones of Kemerovo Oblast), semi-arid (steppe of Khakassia), arid and arid extra-continental (steppe of Tuva) climate were analyzed. The research shows that values of lythogene potential of humus accumulating in soils of coal-mine dumps of Siberia are proportional to the content of fine-dispersed fractions, and related to certain intervals for each soil type. An increase of value of the lythogene potential of humus accumulating is registered in the evolution line. Initial embryozems have minimum potential (from 0.6 to 2 %). Organic-accumulating and turf embryozems have the following values of potential: from 1.8 to 3.5 % and from 3.5 to 4.0 % respectively. Humus-accumulating embryozems are characterized by the maximum potential value of about 5.5 %. It is shown that best conditions for lythogene humus accumulating base formation are in regions with the aridity index of about 0 (sub-humid and semi-arid climate). Values of lythogene potential of humus-accumulating decrease when aridity or humidity increases. It is observed that lythogene potential of humus accumulating is determined by soil evolution stage and climate conditions. Humid regions are an exception, because the potential of all soil types stays at the level of initial embryozems. Thus, results of the research allow forecasting maximum values of humus content in soils under certain conditions. The use of such index as lythogene potential of humus accumulating creates new opportunities for research of ecologic conditions and resource potential of soils in man-caused landscapes.
