Potential soil erosion risk on arable soils in Germany 1:1,000,000 (WMS)

The Potential Soil Erosion Risk map gives an overview of the exposure of arable soils to soil loss due to surface runoff and splash erosion in Germany. It is based on pedological, relief and climatic factors. The map was created by using the long-term model USLE (Universal Soil Loss Equation). The method is published in the DIN 19708:2005-02 and in the documentation of Ad-hoc-AG Boden (representing the soil experts of the geological services of the German federal states). For the application with soil maps, the method was adapted by the Federal Institute for Geosciences and Natural Resources (BGR).The landuse stratified soil map of Germany at scale 1:1,000,000 was used as pedological input to the model. The relief data was derived from the DEM50 of the BKG. The mean annual precipitation data of the period 1961-1990 (DWD) is used to model the erosivity of rainfall. The land use information is derived from CORINE land cover data set (2006).本潜在土壤侵蚀风险图（Potential Soil Erosion Risk Map）概览了德国境内耕地因地表径流与击溅侵蚀引发的土壤流失风险暴露状况。该图的制作基于土壤学、地形地貌与气候因子，采用通用土壤流失方程（Universal Soil Loss Equation，USLE）的长期模型完成。该方法已正式发表于DIN 19708:2005-02标准以及Ad-hoc-AG Boden（德国联邦州地质服务机构土壤专家代表组织）的官方文档中。为适配土壤图的应用需求，德国联邦地球科学与自然资源研究所（BGR，Federal Institute for Geosciences and Natural Resources）对该方法进行了适配调整。模型的土壤学输入数据采用德国1:100万比例尺土地利用分层土壤图。地形数据源自德国联邦测绘与大地测量局（BKG）的50米分辨率数字高程模型（Digital Elevation Model 50，DEM50）数据集。研究采用1961-1990年时段的年均降水数据（德国国家气象局，DWD，Deutscher Wetterdienst）构建降雨侵蚀力模型。土地利用信息则源自CORINE土地覆盖数据集（2006版）。
