摘    要:目的]为云南茶叶产业的健康发展提供必要的参考。方法]测定云南主要茶区普洱、保山、西双版纳、大理等地茶园土壤重金属铅(Pb)、镉(Cd)和铜(Cu)的含量,并结合茶园土壤重金属评价标准和茶园土壤污染分级标准,采用单因子污染指数法和Nemerow污染指数法进行污染评价。结果]结果表明:云南省主要茶区土壤中这3种重金属含量均较低,Pb和Cd平均含量都处在一级水平,Cu平均含量都处在二级水平,Pb和Cd单因子污染指数和综合污染指数均小于1.000,Cu的单因子污染指数和综合污染指数都在1.000~1.500之间。结论]云南主要茶区茶园土壤环境质量总体良好,符合有机茶园土壤环境质量标准。

关 键 词:茶园土壤  重金属  监测  污染评价

Monitoring and Pollution Evaluation of Heavy Metals in the Tea Garden Soils from Main Tea Areas of Yunnan
Abstract:Objective] The research aimed to provide necessary references for the healthy growth of Yunnan tea industry.Method] Three heavy metal ions including Pb,Cd,Cu were determined in the soils of tea gardens from main tea areas(Puer,Baoshan,Xishuangbanna,Dali) of Yunnan.Combining with the health quality standards of the soil and the soil pollution classification standards of tea garden,the single factor pollution indices and Nemerow pollution indices were used to evaluate the pollution situation.Result] The results showed that the contents of Pb,Cd,Cu were low.The average contents of Pb,Cd were in the first level,and the average content of Cu was in the second level.The single factor pollution indexes and Nemerow pollution indices of Pb,Cd were all below 1.000,and that of Cu was between 1.000 and 1.500.Conclusion] The qualities of soil environment in the tea gardens were good on the whole,and it accorded with the soil environment quality standards of the organic tea garden.
Keywords:Tea garden soil  Heavy metal  Monitoring  Pollution assessment
