对我国江南丘陵林区森林土壤微量元素（Ｂ、Ｍｏ、Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ）的含量、分布及影响因子进行了研究。结果表明：该地区森林土壤全量微量元素Ｂ、Ｚｎ、Ｍｎ等含量很低，Ｍｏ、Ｃｕ含量较高，Ｆｅ含量丰富。不同林分类型对土壤中微量元素全量不存在明显影响。有效态微量元素表现为Ｂ、Ｍｏ、Ｃｕ含量很低，Ｚｎ中等，Ｆｅ、Ｍｎ含量丰富。微量元素有效量一般由土壤表层往下逐渐降低。影响该地区微量元素有效量的主要土壤因子是微量元素全量、土壤质地、ｐＨ值、有机质、速效Ｐ、速效Ｋ等。其中有机质的富集显著提高Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ的有效含量，对Ｍｏ的作用不明显，对Ｂ则起减低有效含量的作用。
The contents, distribution and influencing factors of trace elements (B, Mo, Cu, Zn, Fe and Mn) in forest soils in southern China were studied. The results showed that the contents of total trace elements B, Zn, Mn and so on in the forest soils were very low, the content of Mo and Cu was high and the content of Fe was abundant. Different forest types did not significantly affect the total amount of trace elements in soil. Available trace elements are B, Mo, Cu content is very low, Zn is medium, Fe, Mn content is rich. The effective amount of trace elements generally from the soil surface down gradually decreased. The main soil factors that affect the effective amount of trace elements in this area are total trace elements, soil texture, pH value, organic matter, available P, available K and so on. The enrichment of organic matter significantly increased the effective contents of Cu, Zn, Fe and Mn, but had no obvious effect on Mo, but decreased the effective content of B on B.
