Аннотация:The complex of buildings of the main campus of the Lomonosov Moscow State University (LMSU) on the Leninskie Hills (Sparrow Hills) was constructed in the middle of the 20th century. In this paper we can compare results of soil formation under different combinations of low intensity anthropogenic influences within an area of soils 60-70 years old, which were formed on similar technogenic deposits – ‘building grounds’. Pedogenesis is shown to have two main trends, postlithogenic and synlithogenic, depending on the rates of matter accumulation on the soil surface. The matter accumulation can lead to the formation of specific urban humus horizons that are eutrophic and calcareous. The climate warming and increasing humidity have resulted in a particularly intensive organic matter accumulation within areas, where leaf litter has not been removed and composts have been applied.
