| 摘 要： | 本文对闽北低山区森林土壤中的Ｂ，Ｍｏ，Ｃｕ，Ｚｎ，Ｆｅ，Ｍｎ六种微量元素全量和有效量水平，分布，影响因子等进行了研究．结果表明：闽北森林土壤中的全Ｂ、Ｚｎ、Ｍｎ含量均低于全国土壤平均值，属于较低或很低的水平；影响全量的主要土壤因子是土壤质地和ｐＨ值．土壤中有效态微量元素含量除Ｚｎ、Ｆｅ外，其它四种元素含量均低于临界值含量，属于很低水平；其主要影响因子为土壤质地、全量、ｐＨ值和有机质含量． |

| Abstract: | This paper reported the contents,distribution and influencing factors of total and available microelements in forest soils of North Fujian.Results showed that total contents of B,Zn,Mn in soils of this region were all lower than the average contents in China,belonging to the low level.The factors influencing total contents were soil texture and pH values.Available contents of B,Mo,Cu,Mn were lower than their respective critical level,belonging to deficiency level.Soil texture,total contents,pH values and organic matters were the main factors influencing available micronutrients. |
