Through field trials,the method by microwave digestion-flame atomic absorption spectrometry and microwave digestion hydride generation atomic fluorescence spectrometry was used to detect heavy metals contents(Cu、Hg、Pb and As) of soil-Ligusticum chuanxiong Hort.system in Ligusticum chuanxiong Hort.authentic producing areas of Sichuan which were Willow street town of Dujiangyan city,Xu Du village of Dujiangyan city and Qing xing town of pengzhou city.And then their enrichment was studied.This research could provide scientific evidence for GAP production and be controlled of heavy metals enrichment.It can be proposed appropriate measures to reduce heavy metals contents in commodity Ligusticum chuanxiong Hort.
