      abstract = {This paper studied soil erodibility of slope farmland in  Guizhou mountain areas by the plot runoff method, analysis  and test. Results show that the variation coefficient of  erodibility K value calculated according to formula  introduced by Sharply is low and relatively stable and  accurate, so it is a suitable method for calculating  erodibility K value of slope farmland in Guizhou mountain  areas. K value of layer A slope farmland decreases with  increase of years. The erodibility of entire soil layer is  high, and the erosion resistance is weak. From the  influence of different planting system and use types in 4  years, K values of different soil layers decrease, average  reduction of A, B and C layers reaches 3.17%-11.64%  (1.26%-12.34% for layer A, 1.29%-13.80% for layer B, and  1.26%-10.80% for layer C). Except engineering terraced  treatment, the decline of K value of grassland, zoning crop  rotation, economic fruit forest, grain and grass  intercropping, plant hedge, and mixed forest treatment is  higher than farmers’ treatment, and the decline level is  grassland ＞ zoning crop rotation ＞ economic fruit forest ＞  grain and grass intercropping ＞ plant hedge ＞ and mixed  forest treatment. Planting grass and trees is favorable for  lowering erodibility of slope farmland and improving  farmland quality. Interplanting of corns with other plants  can increase plant coverage and species, so it is favorable  for improving erodibility of slope farmland.},
