【摘要】 研究五台山６种主要土壤类型中全钴的含量分布，并对影响其含量分布的一些主要因素进行了分析。结果表明：①五台山土壤中全钴含量范围为１２．７７～２３．３９ｍｇ／ｋｇ，平均含量为１７．３８ｍｇ／ｋｇ，高于全国及世界土壤中钴的平均含量。影响土壤全钴含量的主要因素是土壤母质。②相关分析表明，五台山土壤中全钴含量与全铁、全铜含量呈极显著正相关，且全钴含量与全铜含量关系更为密切；而与土壤有机质、ｐＨ、１～０．０１ｍｍ、０．０１～０．００５ｍｍ、０．００５～０．００１ｍｍ、＜０．００１ｍｍ的土粒含量及全锰含量无明显的相关性。③五台山土壤中全钴含量高于土壤中钴的临界水平更多还原

【Abstract】 Cobalt contents in the main soil types of Wutai Mountain were investigated.The results are summarised as follows:①The total cobalt contents of the main soils in Wutai Mountain range from 12 77 to 23 39mg/kg,with an average of 17 38mg/kg,Which is higher than the average level of China as well as the world.Parent material is the major factor to influence the total cobalt contents in the soils.②Correlation analysis shows that the cobalt content is significantly and positively correlated with the amount of total iron and copper in the soil.However,cobalt contents in soils had no obvious correlations with organic matter content,pH,particle fraction and total manganese content in the soil.更多还原
