Abstract:: In order to explore the effect of different vegetation reclamation models on soil scour resistance of dump, the shrub land (Amorpha acacia), elm forest land, Robinia pseudoacacia forest land, mixed forest land (Robinia pseudoacacia and elm tree mixed), wasteland and cultivated land in Haizhou open-pit coal mine dump of Fuxin City, Liaoning Province, were selected as the study sites. The methods of field sampling and laboratory improvement were used to obtain the evaluation indexes of runoff and sediment content, scour resistance index, root system index and root system strengthening value (ΔANS) to soil erosion resistance. The results showed that the runoff and the sediment content in different reclamation models changed greatly within 6 minutes of scouring, and the sediment contents after 6 minutes was relatively stable with the prolongation of scouring time; the accumulated runoff and sediment content during the soil erosion process in different reclamation models decreased in the order:cultivated land > barren grassland > elm forest land, mixed forest land and Robinia pseudoacacia forest land>shrub forest land; the soil erosion resistance was inversely proportional to the sediment content during soil erosion process, and the soil erosion resistance increased with the prolongation of soil erosion time; the average impact resistance index decreased in the order:shrub land>Robinia pseudoacacia forest land, the mixed forest land, the elm forest land>wasteland and the farmland. The correlation between soil erosion resistance and soil physical and chemical properties shows that the smaller the bulk density is, the greater the porosity is, the higher the clay content is, and the higher the soil compactness is, the stronger the soil scour resistance is. The strengthening values of soil scour resistance (ΔANS) of different reclamation models were in the range of 0.06~0.73, and the percentage of reinforcement was between 28% and 630%; the plant root resistance to soil decreased in the sequence:shrub land > mixed forest land > Robinia pseudoacacia forest land > elm forest land > barren grassland > cultivated land.
