| Abstract: |
| This article takes the slope land of Gaopo village of Liulin town as the experimental point in Yan'an city.The advanced bi-roll method is adopted to illustrate the rules of infiltration rate in different landuse types.The result shows: ① the moisture infiltration rate in different landuse types can all be thoroughly defined through the Horton equation;② the average infiltration and the steadily infiltration attains 1.52(mm/min) and 1.17 mm/min respectively with 200 min in stubble farmland,the rate of whatever the average infiltration or the steadily infiltration is the same,it shows that the stubble farmland is a little higher than the arable land,the grassland,than the road;③ Soil density makes a direct impact on the moisture infiltration,the more the density is,the lower the steadily infiltration is.And there is an exponential function relationship between them. |
