Abstract The condition of soil formation,soil characters and soil development were influenced directly by the measures of soil and water conservation.The development degree of eroded soil is an important base to estimate the changing of soil quality and the effects to environment.To study the development effect of eroded soil is able to offer a gist to improve the environment of the Loess Plateau.This paper analysed the changing of soil physical and chemical properties under measures of soil and water conservation,bosed on the method of a site-specific experiment and the concept of space as a substitute for time.The result showed that the soil water environment and the content of soil organic carbon were increased;then,the soil structure and its functions were improved greatly with the adding of years of measures implemented.It was testified that the measures of soil and water conservation had positive activity for eroded soil development.And it was pointed out that study aspects to be strengthened about the effect of soil and water conservation measures on eroded soil development in the Loess Plateau.
