摘要
Local natural and man-induced environmental changes in the early medievalarchaeological site in the central Russian plain were reconstructed by study of surface and buriedsoil profiles. Natural soils and ecosystems on watersheds were similar to present ones in agreementwith palynological data. In the floodplain there are remains of forest soils and anthropogenichorizons. These formed in ancient urban environments and are buried under recent alluviumindicating that alluvial sedimentation and flood intensities were much less than at present. Ancientman-induced environmental change related to crop growing activity is well documented bypalynological data but corresponding cultivated horizons are found only in few buried profiles,being unstable if left on the surface. Paleopedological signs of the ancient urban environment arevery stable and preserved in surface soils even 1000 years after the settlement stopped functioning.
