Abstract: Using patches + grid pattern and "S" sampling method, a total of 677 samples were collected from surface soil, irrigation water, atmospheric dry-wet deposition, and crops and root soil. By comprehensive grading method, the authors carried out a land quality geochemical evaluation in Wulajie Town of Jilin Province. The evaluation area is 153 km². Based on the comprehensive geochemical grade, the first grade land accounts for 49.32% of the total area, the second grade land for 21.94%, and the third grade land for 28.38%.The contents of heavy metals of Cr, Cu, Zn, As, Cd, Hg, and Pb in the corn in the evaluation area were <0.87,0.91-2.60,15-27,<0.050,0.003-0.018,<0.010,and <0.050 mg/kg,respectively, which were in accordance with the national standards. The variation of soil pH value was 4.43-8.09 with an average of 5.48, and soil acidification was serious. The acidic soil accounts for 78% of the total area, the strong acidic soil accounts for 15%. The comprehensive land quality of this area is at a good level and suitable for planting crops. However, acidification and boron deficiency (0.35 mg/kg) is at 4th level (0.2-0.5 mg/kg), and effective control measures should be taken.
