| 摘 要： | 本文利用地球化学背景资料,采用单项污染指数法和内梅罗综合污染指数法,根据土壤环境质量标准(GB15618-1995)中的二级标准,以茶区11个地层为单元分别对土壤重金属环境质量及该区土壤pH值进行了地球化学评价。评价结果表明,研究区K2j、K1t、K2g1、K2g3和Q2五个地层土壤为清洁区;其余各地层土壤尚清洁。就各单指标指数来看,Cd元素对土壤污染指数作用最大。

| Abstract: | Based on the geochemical data and environmental quality standards for soils (GB 15618-1995), assessment has been done of the soil quality and pH of 11 strata in the study region by employing one index and Nemerow comprehensive index, respectively. The assessment result showed that in the study region, the strata K_2j, K_1t, K_2g~1, K_2g~3 and Q_2 belong to the poilution-free area, other strata are slightly polluted. As a result, Cd has a decisive effect on soil pollution, as viewed from one single index. |
