| Abstract: |
| The paper studies the patterns of runoff and silt generations in different types of slopland, which are of great importance to quantitatively evaluate the efficiency of water and soil conservation by forests and grasses. Using the data of the ten runoff plots located in the Chaijiachuan catchments of Jixian county, Shanxi, the paper analyzes the effects of different land uses and land-mulching mode on runoff and silt generations and elicits that grassland has a weaker capacity to retain rainstorm water than arbor and shrub forestlands do; farmland(slope farmland) is the major land type suffering from slope surface erosion, and natural arbor forests and mixed forests have remarkably higher erosion-preventing capacity than purely artificial forests; the forests of water and soil conservation have a remarkably higher runoff-impounding capacity than cash forests. |
