以苏南丘陵主要森林类型土壤为对象,分析测定了土壤中微量元素Fe,Mn,Cu,Zn,Mo,B的全量和有效量.并对林木叶、枯落物和土壤微量元素的动态特性进行了分析.结果表明：该地区森林土壤全量B,Zn,Mn低于全国平均水平,属低B区;Fe,Mn,Cu全量较为丰富.有效态B,Mo,Cu含量很低,处于临界含量水平以下;有效2n含量稍高,有效Fe,Mn特别丰富.毛竹叶片对各微量元素有较为突出的富集作用;林木叶、枯落物和土壤微量元素的动态变化随林分类型和元素不同而异.与叶相比,土壤微量元素的变幅较大、枯落物是森林土壤微量元素的重要供应库.
The total and effective trace elements Fe, Mn, Cu, Zn, Mo and B in soils of the main forest types in the southern Jiangsu hills were analyzed and determined, and the dynamic characteristics of trace elements in forest leaves, litter and soil The results show that the total amount of soil B, Zn and Mn in the forest is lower than the national average level, and belongs to the low B area. Fe, Mn and Cu are all abundant in abundance, and the contents of effective B, Mo and Cu are very low, The content of effective 2n is slightly higher, and the available Fe and Mn are especially abundant.The leaves of bamboo leaves have a more prominent enrichment for each trace element.The dynamic changes of trace elements in forest leaves, litter and soil vary with the types and elements Different from the leaf.Compared with the leaves, soil microelements amplitude larger, litter is an important supply of forest soil trace elements.
