| 中文摘要: |
| 对陕西16个苹果主产县的47个果园的土壤重金属含量进行了检测分析。结果表明,Cd、Cr、Cu、Pb、Hg、As 6种重金属均有检出,但均未超过无公害苹果产地环境技术条件标准的含量限值;依据绿色苹果产地土壤环境质量标准,除1个采样点土壤的As元素单因子污染指数为1.03外,其余各采样点土壤中各项重金属元素的单因子污染指数均小于1,47个土样的加权综合指数值小于0.56,均属于清洁级。As是今后苹果园土壤重金属监测和控制的重点。 |

| The contents of soil heavy metals of apple orchards were monitored and analyzed on 47 soil sam-
ples in apple orchards of 16 counties of Shaanxi. The result of test showed that the detection rates of Cd，Cr,
Cu, Pb，Hq and As were 100%，but the amounts were all below the permitted level of no-harmful apple pro
ducing environmental standard; according to the permitted level of green apple producing env ironmental stan
dard, the values of the single item pollution index of the soil heavy metals w ere all smaller than 1 except one soil sample As，whose index was 1.03. For 47 soil samples, the values of comprehensive index w ere all smaller than 0.56, belonging to clean grade. As is the focal point to be monitored and controlled from now on. |
