【摘要】 通过对湖北省61个典型茶园的土壤重金属Cu、Pb、As、Hg、Cd和Cr的含量测定,明确了湖北省典型茶园土壤重金属污染状况。结合土壤环境质量评价国家标准,采用单因子污染指数和内梅罗综合污染指数的方法,对湖北省典型茶园土壤重金属污染状况进行了分析评价。结果表明,湖北省茶园土壤环境质量状况良好,符合国家土壤环境质量标准(二级),处于清洁级和尚清洁标准的茶园比例分别为85.2%和13.%,仅有1个茶园出现中度污染。茶园土壤重金属Pb、As和Hg的含量均未超标,个别茶园土壤重金属Cu、Cd和Cr出现超标现象。更多还原

【Abstract】 Though determination of Heavy metals Cu, Pb, As, Hg, Cd and Cr in soil of 61 typical tea gardens in Hubei province, heavy metals pollution status was defined. Using National Standard(GB15618-1995)as evaluation standard , the degree of heavy metal pollution in soils are evaluated by the methods of single factor pollution index and Nemerow integrated index, the result showed , the soil environmental quality of typical tea garden in Hubei province was in good condition, and conformed to the country second standard of soil. Percentage of tea garden soil quality in cleaning class and the grades of clean and relatively clean were 85.2% and 13% respectively, Only one tea gardens soil environmental quality was in middle pollution; Contend of Pb, As and Hg did not exceed standard. Content of Cu, Cd and Cr exceeded standard in soil of individual tea garden.更多还原
