摘要：The terraced field was an important way to develop the high-efficiency agriculture on the loess plateau,however, lots of terraced field were heavily damaged by the extreme rainstorm in 2013. Improving the terracedfield design standard had become a difficulty in recent research. Based on the field observation and similaritytheory, this paper constructed a 1:10 terraced field scale model. The artificial rainfall together with waterreleasing experiments were designed to simulate the soil erosion process in the scale model. The experimentalresults revealed that the erosion process of the prototype in extreme rainstorm could be reappeared underthe experimental condition that the rainfall intensity was 0.395 mm/min and the experiment lasting time was2.68 hours. Both the erosion amount and the erosion gully topography of the scale model could be verified bythe measured data of the prototype. It can be inferred that the equivalent erosive precipitation of the extremerainstorm was 636 mm. And it was an effective method to research the soil and water erosion process andthe terraced field design standard utilizing the terraced field scale model.
