摘　　要：有机质干扰是困扰森林沼泽景观区化探工作多年的问题。对有机质对元素表生地球化学特征的影响机制进行了初步研究,结果表明:有机质主要通过直接吸附元素和改变环境的物理化学条件这两种方式对元素表生地球化学特征产生影响,两者之间又存在着密切的关系。研究结果较好地解释了由于有机质的干扰而使化探异常发生的变化。Disturbance of organic material is a main factor effecting geochemical exploration in forest marsh landscape area for many years. This paper researchs preliminaryly into the disturbed principle of organic material to character of supergene-geochemistry. The result showing that organic material disturbed to character of supergene-geochemistry with absorbed elements directly and changed physicochemical condition of environment. And both of ways has relations closely. Researched conclusion explained better the variation of abnormal of chemical exploration as disturbance of organic material.
