通过1:250 000多目标区域地球化学调查、采样和化验，获得了阜阳市东南部地区表层、深层土壤中22项指标的土壤地球化学背景值、基准值等数据，研究其分布特征，并依据相应规范进行土壤质量评价。结果显示，与邻区（淮北-亳州）土壤基准值相比，N、Mn、I、Cr等8种元素（指标）土壤基准值略高，而P、MgO、S、Cd等8种元素（指标）则低于邻区；N、Corg和Mn土壤背景值高于邻区的土壤背景值；而P、CaO、MgO、S等8种元素（指标）土壤背景值低于邻区。土壤养分主要处于中等水平、土壤环境质量以清洁为主，仅存在少量轻微污染土壤，影响土壤环境的地球化学指标主要为Cd。区内土壤质量综合评价以优质等级为主，约占研究区总面积的76.33%；其次为良好等级，占研究区总面积的23.67%，就此提出了土地资源分质利用的建议。

Through the geochemical survey, sampling and testing of 1:250 000 target areas, the soil geochemical background values and reference values of 22 indicators in surface and deep soils in the southeastern part of Fuyang City were obtained, and their distribution characteristics were studied. Soil quality evaluation was calculated according to the corresponding specifications. The results showed that compared with the soil reference value of the neighboring area (Huaibei-Bozhou), the soil reference values of 8 elements (indicators) such as N, Mn, I and Cr were slightly higher, while 8 elements such as P, MgO, S and Cd (indicators) were lower than the adjacent area; the soil background values of N, Corg and Mn were higher than those of the adjacent area; while the soil background values of 8 elements (indicators) such as P, CaO, MgO and S were lower than the adjacent areas. Soil nutrients were mainly at a medium level, soil environmental quality was mainly clean, and only a small amount of slightly polluted soil existed. The geochemical index affecting the soil environment was mainly Cd. The comprehensive evaluation of soil quality in the area was mainly based on high quality grade, accounting for 76.33% of the total area of the study area; followed by good grade, accounting for 23.67% of the total area of the study area. Therefore, the proposal for the utilization of land resources was proposed.
