摘要

Studies were carried out in the buffer zone of Bialowieza Forest - in agricultural (reclaimed meadow) and forest catchments of the Perebel River. Yielding, sward cover and botanical composition were analysed in 2007. At the river edges the plant and water samples were taken in May and August for analyses of: NO_3~-, NH_4~+, PO_4~(3-). Yield from 2 cuts was 4-8 Mg ha~(-1); the third regrowth was grazed. In the autumn, sward cover ranged from 52% to 76%; the larger followed lower fertilisation rates, smaller yields and grazing, particularly that less intensive. Concentration of mineral nutrients in water samples was higher in May than in August. It was significantly higher in plants and water from meadow than from forest catchment. Vegetation from theriver edges contained many times more mineral nutrients than the outflowing water. Despite significant differences most water samples did not exceeds standards for the I and II water quality classes. The Perebel River carries water of high quality.
