Soil erosion by water is one of the most significant forms of soil degradation globally, especially in Europe. A new soil erosion risk map of Hungary has been compiled and published recently, using the combined outputs of the Universal Soil Loss Equation and Pan-European Soil Erosion Risk Assessment models. Our study aimed at providing evaluation of the map by using semiquantitative validation data obtained from the Hungarian Soil Degradation Subsystem of the National Environmental Information System. The Soil Degradation Subsystem database contained information at farm level as well as indicators based on laboratory data for 5-ha representative plots. On the basis of the semiquantitative analysis, the map results align well with the farm-based degradation data and provide viable information not only at the regional scale but also at the farm scale. However, indicators from representative plots did not support model results, indicating possible conflict between farm- and plot-level data. Cross-comparison of these indicators showed only limited correlation between farm- and plot-level indicators.

评估匈牙利新的土壤侵蚀图 - 一种半定量方法

水土流失是全球土壤退化最重要的形式之一,尤其是在欧洲。最近使用通用土壤流失方程和泛欧土壤侵蚀风险评估模型的组合输出编制并发布了匈牙利的新土壤侵蚀风险图。我们的研究旨在通过使用从国家环境信息系统的匈牙利土壤退化子系统获得的半定量验证数据来对地图进行评估。土壤退化子系统数据库包含农场层面的信息以及基于实验室数据的 5 公顷代表性地块的指标。在半定量分析的基础上,地图结果与基于农场的退化数据非常吻合,不仅在区域范围内而且在农场范围内提供可行的信息。然而,代表性地块的指标不支持模型结果,表明农场和地块级数据之间可能存在冲突。这些指标的交叉比较表明,农场和地块级别的指标之间的相关性有限。
