Abstract
The Characteristics of runoff and sediment in slope land were studied under the natural rainfall condition in Yangpo watershed, locats at upper reaches of Fen River. The results showed that comparing with the average, the precipitation distribution in 2013was variable. Studies on 17 erosive rainfalls in 2013 were analyzed that the relationship about cumulative runoff correlated significantly with the cumulative rainfall and cumulative sediment, with the correlation index of 0.953 4 and 0.925 9 respectively. It was found that a few big intensity rainfalls had great contributions to the amount of runoff and sediment.
