Soil degradation intensity of loess landscapes by different land use systems in Central Europe.

黄土地区拥有中欧最肥沃的土壤。由于这些地貌在集约土地利用下高度脆弱，一些土壤退化过程十分普遍。这项研究旨在通过比较不同土地利用制度下两个黄土区的土壤退化强度，为可持续土地管理的发展提供支持。因此，将在不同尺度上对土壤的地质生态状况进行分析。将指出重大的退化过程。根据评价结果，可以对不同的土地利用制度进行比较和评价。波兰研究区的特点是小规模、低投入、农民耕作制度，而萨克森研究区的特点是大规模、集约化的现代农业。传统的小规模耕作系统通常被视为可持续土地利用的范例。为了能够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来分析土壤生态因素。更重要的指标是腐殖质质量和植物营养含量，它们对目前的土地利用制度很敏感。已经进行了广泛的地理信息系统分析。在此基础上，将对土壤分析结果进行不同尺度的解释。根据研究结果，将针对特定的土地利用制度提出土壤保护的具体措施。

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.
