摘　　要：文章运用痕量相态分析和元素活动态提取技术对森林沼泽景观各类表生介质元素存在形式进行研究,确定各类表生介质中元素存在形式有继承矿物原生状态的相对稳定形式和表生环境下形成的元素活动态形式两类,不同类型介质的元素存在形式具有较大差异。元素赋存形式对评价化探异常具有重要指示作用,介质中成矿元素的有效相态形式占有一定比例是矿异常的重要标志。Element occurrence was studied in different secondary mediums, using trace - element state analysis and element mobile form extracting methods in the forest - swamp landscape. There were two kinds of element occurrence mode in the secondary mediums. One was in stable form in primary minerals, another was in mobile form. A considerable difference of element occurrence was in different type mediums. It was an important indicator that a quite portions of ore - forming elements in effective state forms in the secondary mediums.
