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.

黄土区包含中欧生产力最高的土壤。由于这些景观在密集的土地使用下，这些景观的脆弱性很大，因此几个土壤降解过程很普遍。该研究旨在通过比较以不同土地利用系统为特征的两个黄土区的土壤降解强度来支持可持续土地管理的发展。因此，将在不同的尺度上分析土壤的地球学地位。将指出重大降级过程。根据结果​​，可以对不同土地使用系统进行比较和评估。波兰的研究领域的特征是小规模，低投​​入，农民农业系统，而萨克森研究区则以大规模，密集的现代农业为主。通常认为传统的小规模农业系统是可持续土地使用的例子。为了比较这些农业土地使用系统，将使用地球化学参数和侵蚀状态来分析edaphic生态因素。进一步的重要指标是腐殖质质量和植物营养含量，它们对当前的土地使用系统敏感。已经进行了广泛的GIS分析。在此基础上，将为不同的尺度解释土壤分析的结果。将建议根据特定土地使用系统的特定措施进行土壤保护的特定措施。
