中文摘要：

纸讨论了土壤侵蚀评价的理论和方法论并且根据与题目的纸地图和 DEM 结合的 USLE 因素建立了一个实现过程。USLE 的因素 - R， K， S， L， P 和 C 被使适应测试区域，在 Shaanxi 省的 Chunhua 县的 Nihe Gou 集水，中国。以后， USLE 的参数个别地被评估并且合并了以便在相应的年计算土壤璃的数量， 1977 和 2003。为了导出所有必要因素，听从一张纸轮廓地图被产生。而且，题目的纸地图和气候数据为实现完成了信息的来源。与 GIS 一起综合的量的方法论在这个过程期间被使用。结果的确认被执行在测试区域把真实世界状况与结果作比较题目的地图。它证明这些原则和方法论合理、可行并且能为中国黄土高原的进一步的区域提供基础或参考书。

英文摘要：

The paper discussed theory and methodologies of soil erosion assessment and established an implementation process according to USLE factors combining with thematic paper maps and DEMs. Factors of USLE- R, K, S, L, P and C were adapted to the test area, the Nihe Gou catchment in Chunhua County of Shaanxi Province, China. Afterwards the parameters of the USLE were evaluated individually and merged in order to calculate the amount of soil loss over the corresponding years, 1977 and 2003. In order to derive all necessary factors a TIN was generated out of a paper contour map. Furthermore, thematic paper maps and climate data completed the source of information for the implementation. The quantitative methodologies integrated with GIS were applied during the process. The verification of the result was performed comparing the real world situation at the test area with the resulting thematic maps. It shows these principles and methodologies were reasonable and feasible and can provide basis or reference for further areas of the Chinese Loess Plateau.
