Transport mechanisms of soil water and solute on slope land are important to promote the water and nutrient efficient and protect the water and soil resources in erosive region.According to the results of indoor simulation rainfall experiments,the transport traits of soil PO3-4,K and Br-on loess slope lands with different soil antecedent water content,1.3%,5.7%,9.7%,14.2% and 18.9%,respectively,are investigated.It shows that loss amount and loss percent of solutes climbs with the increase of soil antecedent water content.The mean concentration of solute in surface presents a parabola relation with soil antecedent water content.The mean concentration of 18.9% slope land is the highest,and it of 1.3% slope land is more than that of the 5.7% and 9.7%.The infiltration amount of soil Br-is the most of the three solutes,then K ,and PO3-4 least.Increase of soil antecedent water content will improve the infiltration amount of soil Br-.Km of soil K and PO3-4 is gaining with the increase of water content,and it of soil Brand K is more than that of PO3-4.Quality transport coefficient Km,based on the solute convection-dispersion theory and well reflecting the transport traits of non-adsorbed Br-with surface runoff,is unfit for the impacts of soil erosion on adsorbed soil K and PO3-4 transport.Avoiding spraying fertilizer in rainy season is favorable to lessen the surface loss of soil solute,especially the adsorbed solute.
