- Abstract:
-
Through natural rainfall experiment, soil erosion process on the the typical granite red soil slope and influences of different vegetation planting patterns, rainfall and rainfall intensity on red soil slope surface runoff and sediment yield were analyzed, the effect of different planting patterns on the sediment and water storage efficiency and soil erosion were quantitatively examined under natural rainfall, and the test model was developed. The results show that:(1) under the same rainfall condition, different vegetation planting patterns of relationship between the size of the soil erosion is:the naked model > full cover planting patterns > strip planting patterns > ditch planting patterns; (2) when the average rainfall intensity is 0.3 mm/min, the whole cover planting pattern is superior to the furrow sowing grass planting patterns; when the average rainfall intensity is 0.6 mm/min, a trench planting grass planting patterns of water storage capacity is more significant; (3) the particle size of eroded soil is mainly focused on the less than 0.25 mm, it is the main cause of soil erosion and land degradation, particle sizes of sediment under different vegetation planting patterns are dominated by the sizes < 0.25 mm, the changing rule of the total amount of sediment particle size is as follows:the naked model > full cover planting patterns > strip planting patterns > ditch planting patterns. The effect of furrow sowing grass planting patterns on sediment reduction is the best, which can provide example for management of soil and water loss in the southern area.
