- Аннотация: The content and distribution of particle-size fractions, humus and Mn, Cu, Ni, Co, Cr, Zn, Pb, Ti, Zr, Fe was studied in the humus soil horizons of small watershed, located in the Central Russian Upland (Plava river basin). The distribution of particle-size fractions in topographic features was characterized by low contrast. The weak trends of fine fractions removal were detected in the areas with intense flows and accumulation at the grass-covered slopes. The metal contents in the system: autonomous landscapes - slight slopes - steep slopes - the lower part of the slopes - the bottom - were slightly distinguished. Contents of all metals, except for Cu and Mo, increased in soils of slight slopes. The trend of concentration increase is detected for Co, Cr, Ti, Zr on steep slopes. The Cu, Zn, Pb, Ni, Mn and Fe contents on steep slopes decreased in relation to slight slopes. Contents of all metals except for Mo, Ti and Zr, were higher in bottom soils than in autonomous soil. The linear trends for Zr, Ti accumulation and for Mn, Ni dispersion, and in a less degree for Cr dispersion, were revealed along the bottom, from the upper to the lower reaches. The coincidence in distribution types of Pb, Ti, Fe and clay fraction, was found out.
