摘要: An assessment was made of the capacity base cations to neutralize acid deposition and contribution cation forest nutrition in Europe. In large parts southern Europe more than 50% potential found counteracted by non-sea salt Mg2+ + Ca2+ K+. central northwestern Europe, usually amounted less 25% Input. Smallest relative Scandinavia, Denmark, northern Germany The Netherlands. A similar spatial pattern for neutralization anions precipitation. Whereas Scandinavia weathering is dominant supplier soils, eastern forests mainly rely on atmospheric supply cations. Using error propagation, random systematic an average grid cell 10 x 20 km estimated equal 45-55% 50-55%, respectively.
