Loess areas contain the most productive soils in Central Europe. Several soil degradation processes are widespread because of a high vulnerability of these landscapes under intensive land use. The study aims to support the development of a sustainable land management by comparing soil degradation intensities in two loess areas characterized by different land use systems. Therefore, the geoecological status of soils will be analyzed on different scales. Significant degradation processes will be pointed out. Based on the results the comparison and evaluation of the different land use systems can be done. The research area in Poland is characterized by a small scale, low input, peasant farming system, whereas the Saxonian study area is dominated by large scale, intensive modern farming. Traditional, small scale farming systems are usually seen to be examples for sustainable land use. To enable a comparison of these agricultural land use systems edaphic ecological factors will be analyzed using geochemical parameters and the erosional status. Further important indicators are humus quality and plant nutrition content which are sensitive to the current land use systems. Extensive GIS analyzes have already been done. On this basis the results of the soil analyses will be interpreted for different scales. Basing on the results specific measures for soil protection will be advised relating to the particular land use system.

黄土地区拥有中欧最肥沃的土壤。由于这些景观在集约土地利用下的高度脆弱性，一些土壤退化过程很普遍。本研究旨在通过比较两个不同土地利用系统的黄土地区的土壤退化强度，支持可持续土地管理的发展。因此，将在不同尺度上分析土壤的地质生态状况。将指出重要的降解过程。在此基础上，可以对不同的土地利用系统进行比较和评价。波兰的研究区以小规模、低投入的农民耕作系统为特点，而萨克森的研究区则以大规模、集约化的现代耕作为主。传统的小规模农业系统通常被视为可持续土地利用的范例。为了对这些农业土地利用系统进行比较，将利用地球化学参数和侵蚀状况分析土壤生态因子。另外重要的指标是腐殖质质量和植物营养含量，它们对当前的土地利用系统很敏感。广泛的GIS分析已经完成。在此基础上，对不同尺度的土壤分析结果进行解释。在此基础上，针对具体的土地利用系统，提出具体的土壤保护措施。
