Abstract This study presents the updated version of the recently published LANDUM model [Land Use Policy 48, 38–50 (2015)]. LANDUM is integrated into the 100 m resolution RUSLE-based pan-European soil erosion risk modelling platform of the European Commission. It estimates the effects of local land use and management practices on the magnitude of soil erosion across each NUTS2 region of the European Union. This is done based on a spatially explicit estimation of the so-called cover-management factor of (R)USLE family models which is also known as C-factor. In this updated version, the data on soil conservation measures (i.e., reduced tillage, cover crops and plant residues) reported in the latest EU Farm Structure Survey (2016) were integrated and elaborated in LANDUM in order to estimate the changes of the C-factor in Europe between 2010 and 2016. For 2016, a C-factor of 0.2316 for the arable land of the 28 Member States of the European Union was estimated. This implies an overall decrease of C-factor of ca. -0.84 % compared to the 2010 survey. The change in C-factor from 2010 to 2016 could be an indication for the effectiveness of Common Agricultural Policy (CAP) soil conservation measures in reducing soil erosion in Europe, especially key CAP policies such as Good Agricultural and Environmental Conditions and Greening.

反映共同农业政策对土壤侵蚀减缓作用的指标

摘要 本研究介绍了最近发布的 LANDUM 模型 [Land Use Policy 48, 38–50 (2015)] 的更新版本。LANDUM 已集成到欧盟委员会基于 100 m 分辨率 RUSLE 的泛欧土壤侵蚀风险建模平台中。它估计了当地土地使用和管理实践对欧盟每个 NUTS2 地区土壤侵蚀程度的影响。这是基于对 (R)USLE 系列模型的所谓覆盖管理因子（也称为 C 因子）的空间明确估计来完成的。在此更新版本中，最新的欧盟农场结构调查（2016 年）中报告的土壤保持措施（即减少耕作、覆盖作物和植物残留）的数据在 LANDUM 中进行了整合和阐述，以估计 C- 2010 年至 2016 年间欧洲的因素。2016 年，欧盟 28 个成员国的耕地的 C 因子估计为 0.2316。这意味着大约 C 因子的整体下降。-0.84 % 与 2010 年的调查相比。2010 年至 2016 年 C 因子的变化可能表明共同农业政策 (CAP) 土壤保护措施在减少欧洲土壤侵蚀方面的有效性，特别是关键的 CAP 政策，如良好的农业和环境条件以及绿化。
