- Abstract:
-
The runoff amount and soil erosion amount on different rainfall and different underlying horizon were analyzed in base of yellow river institute of hydraulic research at 2008.The results show:the runoff of bare slope and farm slope were increasingly with time,they got the steady runoff at experiment 30 min,they are 10 kg/min which is 40 times that of grass slope in small rainfall;the runoff amount of bare slope and farm slope are 7 times that of grass slope in middle rainfall;the runoff of grass slope was slowly increasing at the initial stage,it got the steady runoff at experiment continue 12 min,it’s 10 kg/min in heavy rainfall,the runoff of bare slope and farm slope were rapidly increasing at the initial stage,they got the maximum runoff at experiment continue 20 min,then they keep a low-level runoff amount in heavy rainfall.The soil erosion of bare slope and farm slope were 10 kg which were 20 times that of grass slope in small rainfall;The soil erosion amount of bare slope and farm slope is 100 times that of grass slope in middle rainfall;the soil erosion of bare slope and farm slope were rapidly increasing at the initial stage,they got the maximum soil erosion at experiment continue 18 min,then they keep a low-level soil erosion amount in heavy rainfall;the grass to cover slope could reduce the soil erosion in small and middle rainfall on the Loess Plateau.
