Abstract:ln order to explore the soil anti-scouribility under different vegetation planting modes and find out the best vegetation planting patterns for soil and water conservation in red soil region, the soil under different planting modes in red soil hilly region was selected as the research object. The soil anti-scouribility under three different scouring flow (1.5, 2.5, 3.5 L/min) was studied by wet screening method and the undisturbed soil sample washing experiment. The results showed that:(1) The coefficients of soil anti-scouribility under different vegetation planting patterns ranged as:stripe grass shrub belt > geomantic forest > planting grass on the whole slope > mango rake land > closure land > bare land > reclaimed land. The scouring sediment yield of the three scouring flows was in a low level equilibrium state. The scouring sediment yield ranged from 0.01~1.12, 0.02~1.53 and 0.02~2.57 g, respectively. CK1 and CK2 had the largest scouring sediment yield, ranging from 0.08~65.20, 0.07~60.56 and 0.24~80.60 g, respectively. (2) Soil total porosity,>0.25 mm water-stable aggregates content, root surface area, root volume, root length and root biomass in trench grass irrigation belt and geomantic forest accounted for 37.08%, 80.38%, 44.15%, 45.12%, 52.11% and 57.91% of all modes respectively. (3) The average weight diameter (MWD), geometric mean diameter (GMD) of soil aggregates, root length density and root weight density were the larger in the shrub belts and geomantic forests, accounting for 55.76%, 44.06%, 52.18% and 54.91% of all modes, respectively. The results could provide reference for controlling soil erosion and revealing the mechanism of erosion in red soil region.
