Abstract:: The paper studies observational data on runoff and soil erosion in runoff-plots of different grass,different slope gradient,different cover degree in Linqu,Mengyin,Qufu three soil and water conservation experimental stations.The results show that there are good linear relation between rainfall and runoff and between rainfall and soil erosion on the same slope gradient,the different crops and the same cover degree,different slope gradient and the same slope gradient,the different cover degree in grass runoff-plots.There are good logarithmic relation between rainfall intensity and runoff and between rainfall intensity and soil erosion.With the increase of rainfall and rainfall intensity,runoff and soil erosion are increasing.Anticipated empirical model on water and soil erosion for grass land in mountain areas of middle southern of Shandong province for runoff and soil erosion are educed.
