Abstract:: Synthetic index method was adopted to evaluate the farmland productivity of Qindu District. On the basis of investigating the farmland productivity, 12 targets from 4 aspects of soil condition, soil properties, soil fertility and soil management of Qindu District of Shaanxi Province located in Guanzhong plain were selected. The farmland productivity was evaluated automatically, quantitatively and visually with the integrated use of GIS, analytical Hhierarch program (AHP) and fuzzy mathematical theory (FMT). The results indicated that farmland productivity in Qindu District could be divided into 4 grades. The areas of grades 1—4 accounted for 52.08%, 39.72%, 7.35%, and 0.85% of the total arable land areas, repectively, levels of the farmland productivity are higher. Analysis of the spatial distribution characteristics of each grade is beneficial for scientific management and sustainable use of farmland resources. This result can not only be applied to Qindu District agriculture production, but also contribute a beneficial exploration for studies about the evaluation of the farmland fertility of Guanzhong plain as well.
