| 摘要: |
| 以陕西关中(塿)土、陕北黄绵土及陕南水稻土为重点,兼顾其它土类,共采集土壤样品947个,对其进行了铬、砷、汞、铅、铜、锌、镉、镍、硒、氟等十种元素的测定,在土壤剖面中还测定了钛。测定结果经数理统计,确定了以上十种元素在不同土类中的分布类型及环境背景值,绘制了背景值分级图,并探讨了不同元素在各土类中的水平和垂直分布情况。 |

| Abstract: |
| 947 soil samples were collected with priority given to Lotu soil in Guanzhong,cultiyated loessal soil in north Shaanxi and paddy soil in south Shaanxi and with other soil types taken into account.The chemicals elments such as Cr/As/Hg/Pb/Cu/Zn/Cd/Ni/Se/F were determined in these soil samples with Ti in soil profile done as well. Work had been done with AQC.The determined results being subject to statistics decided the distribution patterns and background values of more than ten elements in different soil types so that the classification of background values was mapped out.Also,the horizontal and vertical distribution of different elements in different soil types were discussed. |
| Key words: background value,agricural soil,pollution elements,map of classification of background values |
