摘要：

Fluxes of dissolved mineral elements have been monitored in a declining spruce stand in northern Bohemia. This area is subjected to very high atmospheric pollution. Mean annual throughfall pH was 3.15 and monthly mean values as low as 2.6 were recorded. Measurements show deposition values per ha and per year as high as 150 kg S, 60 kg Ca and 12 kg Al as well as a proton input > 5 keq/ha/yr H+. Part of the input was immobilized in the litter layer and the remaining acid load was buffered by Al release in the mineral horizons. High nutrient inputs may explain why no mineral deficiencies have been detected, although tree mortality is extremely high in this area.
