Ten runoff plots with different planting patterns were established for experimental observation in the Longli soil and water conservation demonstration area of science and technology in karst region of Guizhou Province.Results show that under the same rainfall condition
shrub land(such as Rubus idaeus)
natural grassland and abandoned land presented the best function of soil and water conservation. Runoff yields on the three kinds of land were 0.71
0.74 and 0.71m3 and sediment yields
20.3
20.3 and 20.16g. The function of soil and water conservation was poor for arbor planting pattern
because the shrub layer
herb layer and forest floor were not formed. Runoff yields for the three plots with arbor planting pattern were 1.18
0.98 and 0.95m3 and sediment yields
119.56
126.56 and 125.89g. Because of no-tillage
sur-face crust and other effects
the function of soil and water conservation in slope farmland was better than that in runoff plots with arbor planting pattern.
