目的：连续多年监测彭州敖平镇川芎药材栽培土壤中重金属镉的含量，分析其对川芎药材中镉含量的影响。方法根据前期研究结果选取敖平镇部分川芎种植地固定采集样品。按照国家标准方法，采取0～20 cm连续根系土柱和川芎药材。采用火焰法对抽样土壤及川芎药材中镉的含量进行检测分析。结果采样区域内土壤中镉含量均符合国家二级土壤环境质量标准；部分土壤中镉的含量呈明显增长趋势。结论川芎种植土壤中镉含量与环境有较高关联，水泥厂粉尘等污染源是土壤中镉含量增加的重要来源。

Objective Continuous monitoring on the cadmium in the plant root soils of rhizoma chuanxiong of Ao'Pin town to found out the source of heavy metal elements in Rhizoma Chuanxiong . Methods The content of cadmium were detected by AAS .Results The content of cadmium in the plant root roils of rhizoma chuanxiong conformed to GB standard .The content of cadmium in the plant root soils of rhizoma chuanxiong was larger than those in the soils and surpassed the standard .Conclusion Cadmium in the rhizoma chuanxiong planting soil content and environment have a higher associated , cement plant dust pollution in soil is an important source of cadmium content increased .
