摘要

Soil erosion is a serious worldwide problem. It leads to a particular form of degradation in which land loses its productive capacity. Soil erosion is also considerable in central Germany. Since this region is characterized by highly fertile black soils, agriculture is very important there. The land is covered by large fields with only few structural elements like hedges, small forests, copses and field edges, exposing it to the risk of soil erosion. However, it is important that farmers, landscape planners, environmental and local authorities take steps to combat soil erosion, while simultaneously taking into account other landscape functions such as water discharge regulation and the crop production capacity. After all, only if production capacity is regarded as the basis of their income will farmers be willing to take action to ensure higher biodiversity in their fields. This involves giving up part of their fertile farmland by changing it into hedges, copses or extensive meadows. Therefore a suitable approach was developed which includes various landscape functions and is geared to the specific landscape involved. This approach is based on the assessment of different functions with subsequent multicriteria optimization. A draft landscape plan is added. The approach and the results are introduced and discussed in the following paper.
