摘要(Abstract)：

【目的】土壤侵蚀是一种日益严重的生态问题，已经成为全球性的环境挑战，对人类的生存和可持续发展产生了极大的威胁。因此基于多源遥感数据，【方法】通过RUSLE模型和地理探测器模型研究了1990—2020年京津冀地区土壤侵蚀在时空尺度上的动态变化，并对其驱动因素进行了分析。【结果】结果显示：(1) 1990—2020年京津冀地区的土壤侵蚀总体呈现东南低西北高的分布特征，且以微度和轻度侵蚀为主，其百分比达到73.79%。(2)京津冀大部分地区土壤侵蚀等级主要由高向微强度侵蚀转移，且转移比例都在50%以上，整体有所好转，但存在局部加剧。(3)各个影响因子对土壤侵蚀的解释力依次为：坡度>高程>土地覆盖类型>植被覆盖度>降雨量>人口密度>GDP。【结论】相关结论可为水土流失治理以及防治提供一定的科学参考，同时也可为其他地区的土壤侵蚀治理提供参考。
