Porovnání a dlouhodobý trend látkových toků tří malých povodí na Šumavě

Original language description

Changes in the chemistry of bulk precipitation and stream water between 1999 and 2007 are described for small drained, wetland and forest catchments located within Šumava Mountains (Bohemian Forest) in southwest of the Czech Republic. The paper is focused on interpretation of hydrochemical trends in selected time periods, especially on effect of deposition changes and landscape management. In bulk precipitation, the annual mean pH increased from 4.8 to 5.6, concentrations of base cations were rela-tively low and constant over time, nitrate moderately increased, conductivity and alkalinity decreased, as well as sulphate decreased (from 16.8 mg.l-1 to 2.8 mg.l-1) during the 8 years of monitoring period. Catchments with wetland and forest appear to be more resistant to recovery in terms of water conduc-tivity, alkalinity and base cations in comparison with the relatively fast response from the drained pas-ture. High nitrate, bicarbonate and base cations concentrations in the stream water
