摘要
对我国东北北部森林沼泽景观各种采样介质元素存在形式进行研究 ,确定这类地区元素存在形式有碎屑形式和元素活动态形式两类。实际资料表明 ,元素存在形式对采样介质、采样粒度、采样方法的确定有重要影响 ,对研究区景观地球化学特征、元素迁移富集机制研究和化探异常评价具有重要意义。通过试验研究确定了森林沼泽景观区中大比例尺化探工作方法。
An investigation on the mode of element occurrence in various samples collected from forest-bog area in northeastern China has been carried out. The mode of elements in the area includes detrital and mobile forms. The results show that the element form is a key factor for selecting the sample materials and grain size as well as sampling method. It is also very helpful for the researches on landscape geochemistry, mechanism of element transformation and enrichment, and evaluation of geochemical anomalies. A suitable geochemical prospecting method of middle-large scale is suggested in the forest-bog area.
