为道真县茶园的管理提供依据，对道真县11个乡镇的无公害茶叶生产园区土壤取样，用原子（荧光）吸收分光光度法测定 Pb、Cd、Cr、Cu、Hg 和 As 的含量，以《土壤环境质量标准 GB15618-1995》为依据，采用单因子污染指数和综合污染指数进行评价。结果表明：道真县11个乡镇的茶园区土壤中，洛龙镇的土壤综合污染指数为0．74，Cd 单因子污染指数0．97，处于警戒级别；其余乡镇土壤的单因子污染指数和综合污染指数都小于0．7，处于安全级别。土壤重金属含量除隆兴镇的保持与背景值一致外，其他乡镇的有不同程度的升高。

The Pb、Cd、Cr、Cu、Hg and As content of 200 soil samples from tea gardens of 11 villages and towns in Daozhen County was determined by atomic absorption spectrometry and the pollution status of heavy metals was evaluated by single-factor polluting and integrated pollution indexes according to The Soil Environmental Quality Standard (GB 15618-1995)to provide the scientific basis for construction of tea garden,tea quality safety and sustainable development in agriculture.The results showed that the soils of tea gardens from 11 villages and towns were polluted with heavy metals to varying degrees except for the soil background value in Longxing Town from soil background value,single-factor pollution index and integrated pollution index.The soil integrated pollution index in Luolong town was 0.74,which is in the alert level and the soil of other villages and towns is in the safety level.The soils along the line of the provincial road,soil of County's and town's locations,and soil of the old tea gardens was polluted by Pb, Pb,Cd and Hg,and Cu respectively.The soil pollution degree along the lines of the provincial road and suburbs is higher than out suburbs.The soils of tea gardens in 11 villages and towns of Daozhen County all are suitable to developing tea industry.
