坡面侵蚀产沙信息的获取对土壤侵蚀预报模型开发和相关参数获取至关重要。采用如下方法放水冲刷法和人工模拟降雨法，通过不同的放水流量、雨强，在5 m坡长坡面上利用REE示踪法;在4 m长坡面和3 m长沟坡组成的坡沟系统上，用地形测针板法和坡面侵蚀沟量算法;在8 m长坡面和5 m长沟坡组成的坡沟系统上，用地形测针板和HDS3000高精度扫描仪测量法等，对不同空间尺度、不同侵蚀测量方法的测定结果进行了对比分析。结果表明几种方法的测量精度高低依次为HDS3000扫描仪法＞REE示踪法＞地形测针板法＞侵蚀沟量测法;工作效率高低依次为HDS3000扫描仪法＞侵蚀沟量测法＞地形测针板法＞REE示踪法。在坡面侵蚀空间分布上几种方法都可实现，但精度各有不同，实际应用中应根据需求选用不同的测量方法。

Acquiring of slope erosion information is very important to build erosion prediction model and obtain relevant parameters. By using artificial simulated rainfall experiments and scouring experiments, 3 physical models were established in the presence of different discharges and rainfall intensities slope-gully system of 5 meters long straight slope by using REE tracer method, slope-gully system of the 4 meters long slope and 3 meters long gully slope by using topography needle plate measuring method and rill measurement method , and slope-gully system of the 8 meters long slope and 5 meters long gully slope by using topography needle plate measuring method and HDS3000 scanner method . Different measuring methods for slope erosion were analyzed in this paper. The results show that HDS3000 scanner method is the most precise, followed by REE tracer method, topography needle plate measuring method and rill measurement method. HDS3000 scanner method has the highest efficiency, followed by rill measurement method, topography needle plate measuring method and REE tracer method. These methods all can be used to measure the erosion spatial distribution on slope, but the precision is different among them. Therefore, in the study of soil erosion, suitable measuring method should be chosen to meet actual need.
