Abstract in another language

The impact of anthropogenic depositions on soil and groundwater quality has been subject to numerous studies in the last two decades. However, the problem of linking results and models of different scales remains to be solved. A case study has been performed in the Fichtelgebirge region in South-East Germany. Data from this case study has been used to analyse scale dependences of spatial variance, autocorrelation lengths and interdependeces of soil hydrological and soil chemical parameters.For soil suction, spatial variability increases stepwise with scale. Three different sources of variation, predominating at different ranges of scale, could be identified which makes a deterministic mapping feasible.Local SO4 deposition explained much of the spatial patterns of SO4 concentration in soil solution and catchment runoff observed at different scales. This is mainly due to the fact that the sorption capacity of the soils in this region is exceeded at present. Decreasing SO4 deposition in the long term run is likely to enhance the influence of the soil, and reduces the correlation between deposition and soil solution concentration. NO3 showed minimum variation at the county scale. This seems to be a reasonable representative elementary area for mapping regional NO3 concentration patterns. For protons and Cl, neither observed spatial patterns nor the scale dependence of spatial heterogeneity could be explained adequately.
