Based on geochemical indicators affecting the quality of land such as nutrition elements, harmful elements and compounds, organic pollutants, and physical-chemical properties, the authors assigned the weight of each index by using analytic hierarchy and set up the corresponding membership function to get the function value which could be used to classify the land levels. The results indicate that land quality of the Jitai Basin in Jiangxi Province is good. The area of high-level land is 9 640.94 km², accounting for 85.98% of the study area, the medium-level land accounts for 13.75% and the poor-level land accounts for 0.27%. The results of the study provide geochemical foundation for adjusting agricultural planting structure, developing characteristic agricultural products, and promoting reasonable fertilization in the Jitai Basin. The countermeasures are put forward for soil pollution regulation, such as the application of lime (CaCO₃) to reduce the acidity of soil, the increasing application of organic fertilizer and the utilization of phosphate.
