摘要
对云南省土壤锰元素背景值进行了采样分析,结果显示:锰元素含量呈对数正态分布,中位值560 0mg/kg,几何均值486 5mg/kg,95%置值区间18 3～1648 4mg/kg。并对其特征进行了研究。
The article samples the soil and analyzes the background value of manganese element in Yunnan province, the results show that the contents of manganese element is log-normal distribution, the median is 560.0 mg/kg, the geometric mean is 486.5 mg/kg, the confidence interval of 95 percent is 18.3 to 1648.4 mg/kg,.
