摘　　要：本文用随机布点法,采集了简阳东溪镇土壤样品29个,分析了土壤中Cd、Zn、N i、Cu、Mn、Pb六种元素含量,用Shap iro-W ilk法和偏态系数检验了土壤中的元素含量分布类型,结果六种元素含量均为正态分布。根据元素含量类型分布,统计简阳东溪镇土壤中六种元素平均含量为:Cd 0.295ppm、Zn 62.5ppm、N i 27.49ppm、Cu 23.25ppm、Mn 157.25ppm、Pb17.47ppm。29 soil samples were collected at randomly selected points in Dongxi Town of Jianyang County. The contents of six elements consisting of Cd, Zn, Ni, Cu, Mn and Pb in the soil were analyzed. The distribution types of the six elements were analyzed by means of Shapiro - Wilk and coefficient of skewness. The results showed that for every one of the six elements, it appeared normal distribution. According to the statistic data, the content for the elements Cd, Zn, Ni, Cu, Mn and Pb were 0. 295, 62.5, 27.49, 23.25, 157.25 and 17.47 ppm, respectively.
