贵州省余庆县太子参基地土壤环境质量监测与评价

Evaluation of Soil Environmental Quality of Radix Pesudostellariae Base in Yuqing County,Guizhou

对贵州省余庆县太子参基地土壤中的重金属Cd、As、Hg、Cu、Pb、Cr的含量进行测定,然后采用单因子污染指数法和综合污染指数法进行评价。结果表明,土壤中Cd、As、Hg、Cu、Pb、Cr含量都较低,单因子污染指数和多因子污染指数值均小于1.0,属于污染等级中的安全级,完全符合种植无公害中药材太子参的土壤环境条件。

Monitor of heavy metals including Cd, As, Hg, Cu, Pb and Cr in soils placed in Radix PesadostelUariae planting base, Yuqing county, Guizhou, China was carried out in the present study. Methods of evaluation utilized are the indexes of single factor and multi -factor pollution. Cd, As, Hg, Cu, Pb and Cr from the soils are all in accordance with the standard of regulations. Also indexes of single factor and multi - factor pollution are all below 1.0 which is belong to the safe level of pollution standards. It maybe suggested that planting Radix Pesadostelllariae in the conditions be accepted.
