In order to find the effect of soil macropore distribution on overland flow and solute transport, artificial rainfall experients were carried out. The results showed that compared to original macropore soil tank, in the increased density macropore soil tank with the surface porosity of 57% and the volume porosity of 0.285%, the increasing extents of the soil water content of every layer were less, the velocity of overland flow was smaller and the runoff amount of surface was less, the runoff amount of underflow appears earlier and was more in increasing-density macropore soil tank. The results also indicated that in increased density macropore soil tank, the concentration of Br^-, NH₄⁺ and NO₃^- in surface runoff were lower, the concentrations of Br^- and NO₃^- in the underflow runoff were higher in earlier stage of the groundwater outflow, but the concentration of NH₄⁺ was lower and the increasing extend was smaller.
