Abstract

The coupling and integration of models from different disciplines to an interdisciplinary modeling network facilitates the simultaneous description of effects due to ecological, economical or legal changes of land management in selected areas of the natural environment. In all these models soils play a crucial role with their physical and chemical characteristics. In the Interdisciplinary Research Project "Land use concepts for peripheral regions" (Sonderforschungsbereich SFB 299) three mesoscale GIS-based models are developed and adapted to specific conditions of a low German mountain range: the comparative static economic model ProLand, the habitat models ANIMO, ELLA, and YELL, and the hydrological continuum model SWAT. As an example of the interdisciplinary model network, it is demonstrated how changes in land management due to increasing field size affect the landscape services natural production, economic output, water balance, and biodiversity. Numerous soil parameters are employed simultaneously in a variety of modules and processes in these models. The economic model ProLand requires soil data to assess tillage costs, the potential yield from agriculture and forestry production. In order to regionalize the occurrence of typical species by ANIMO and ELLA, universal soil descriptions in combination with exposure classes are formulated and delineated by GIS on the basis of a soil map at 1:50,000 and a digital elevation model. Especially soil physical properties are input parameter of high sensitivity for the hydrological model SWAT. Whenever soil parameters are to be used in interdisciplinary modeling approaches great care must be devoted whether the preconditions for such an application are fulfilled. This problem is pointed out by some examples.
