：In order to explore the impact of ecological planting pattern on runoff sediment transport rate(T ₂), this study in two planting modes with a single planting of Prunella vulgaris (A) and P. vulgaris and earthworms (B) were investigated through simulated rainfall experiments in the field. The results showed that: 1) T ₂ decreased first and then stabilized with the rainfall duration,which is dominated by the composition of soil particle size and runoff depth;2) T ₂ under gentle slope and steep slope conditions is greatly affected by rainfall intensity and slope, respectively; 3) T ₂ ,which has a good correlation with runoff separation rate (D ₂), needs to be explained in conjunction with soil properties or raindrop kinetic energy. The main controlling factors of T ₂ in bare slope, B, A are raindrop kinetic energy, D ₂, and organic matter, which explain 93.10%, 95.76%, and 98.65%.Compared with B, A has obvious economic and ecological value.
