Qapqal County, Xinjiang Wei Autonous Region was selected as the study object. The authors proposed four indexes, i. e., land utilization intensification coefficient, land consumption returns coefficient, land production coefficient, and land contamination coefficient. The coefficients were then used to evaluate the quality and sustainable utilization of land in Qapqal County, Xinjiang Wei Autonous Region. Results show that the land utilization intensification coefficient is lower. Although the land consumption redound coefficient is higher, the productivity of land is not raised as much as possible. In addition, the phenomenon of soil pollution and degradation in Qapqal Conty is serious, which rest ricts the sustainable development of agricult ural economy. From now on, we should strengthen intensification utilization of land resources and scientifically use fertilizer and chemicals to reduce soil pollution. In this way, we can promote the sustainable utilization of soil resources in Qapqal County.
