摘    要:为贵定茶园区的优选和建设提供科学依据,对贵定县5个乡镇茶园土壤pH值及铅、镉、铬、铜、汞、砷6种重金属元素含量进行了检测及统计分析,以无公害茶叶产地环境条件中土壤环境要求为背景值作为标准对其单项和综合污染指数进行分析评价。结果表明:调查区域内土壤重金属含量差异较大,且部分受到了不同程度的污染。在重金属污染因子中,Hg是主要污染因子,其次是Cd。

关 键 词:茶园土壤  重金属  污染评价  贵定  贵州

Abstract:In order to provide a scientific reference for optimization and construction of Guiding tea gardens,the pH values and contents of Pb,Cd,Cr,Cu,Hg and As in tea plantation soil samples collected from five villages and towns in Guiding County were determined and analyzed,and the single and comprehensive pollution indexes were analyzed and evaluated,taking the soil environment requirement of pollution-free tea production areas as the background values.The results showed that the contents of heavy metals in the soil varied markedly.Some areas were polluted in varying degrees.The major pollution factor was Hg,followed by Cd.
Keywords:soil of tea garden  heavy metal  pollution evaluation  Guiding  Guizhou
