As the representative of the northern Loess Plateau gully region, the soil quality under different cultivation length of the orchard in Changwu county was studied. Using partial correlation coefficient to determine the weight, combined with evaluation of membership Sanction to evaluate soil quality levels of the area, the trend of orchard soil quality under different cultivation years was analyzed. The results showed that the IFI values of orchard soil were between 0.22 and 0.70, 27% of them reached the second soil quality standards, 64% reached a third-level soil quality standards, 9% met the fourth standards of soil quality.
