采用激光诱导击穿光谱法(LIBS)检测保定周边三个产粮基地土壤中的重金属元素，并利用光谱定量法分析元素浓度。结果表明，三个基地中元素Cd 和Hg 的含量均未超过国家颁布的《土壤环境质量标准》(GB 15618－1995)中二类土壤标准。

A laser-induced breakdown spectroscopy (LIBS) system is developed for the determination of heavy metals in cultivated land around the city of Baoding, China. The element composition of the soil is determined by a quantitative spectrum analysis. The results show that the concentrations of Cd and Hg in three base soil samples do not exceed the limits specified by the second- class soil standard“Environmental quality standard for soils”(GB 15618-1995) issued by the state.
