　　对浙江省台州市4个县的90个油茶基地土壤样品中铅、镉、铜、锌、铬和砷含量进行了测定，结果表明，土壤中6种重金属均有检出，从平均值来看，重金属含量从高到低依次为Zn、Cr、Pb、Cu、As、Cd。对照浙江省森林食品基地环境质量标准，采用单因子指数和综合指数法对土壤进行了环境质量评价，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，但重金属综合污染指数接近清洁的临界点。

The concentrations of Pb ,Cd ,Cu ,Zn ,Cr and As were determined from 90 soil samples in Camelliaoleifera Base in four county of Taizhou City of Zhejiang Province .Result shows that the contents of six heavy metals were all discovered in the soil .Average content of heavy metal in soil were ranked in the order of Zn >Cr> Pb>Cu>As> Cd .Compared to environmental quality standard for soil of the Zhejiang Forest Food Base ,environmental quality evaluation were conducted on soil by using single factor index & comprehensive index ;the single-item pollution in-dex of the soil heavy metals are all smaller than one ,but the comprehensive pollution index of the heavy metal was close to the critical point .
