Research on Soil Infiltration Law of Different Landues Types in Jinsha River Dry-Hot Valley

Abstract:

This article takes four different slope lands as the experimental points in Jinsha River dry-hot volley. The double-rings method is adopted to illustrate the soil moisture infiltration characteristics in four different landuse types. The results show that different landues types have obvious differences in soil infiltration capability among four different patterns of landuse. Arbor forest behaved the best infiltration capability and wasteland the worst; the average infiltration and the steadily infiltration attains 1.67mm/min and 0.5mm/min respectively during the first 120min of soil water infiltration process in arbor forest; the rate of whatever the average infiltration or the steadily infiltration express the same regulation: the arbor forest is a little higher than the shrub land, the grassland, than the waste land; the moisture infiltration rate in different landuse types can all be thoroughly defined through the Horton equation; Water infiltration is affected by the soil bulk density. With the bulk density increasing, the steady infiltration rate decreases. And the two are at an exponential function.
