摘　　要：内蒙古大兴安岭河源林场地区属典型的森林沼泽覆盖区,应采用土壤测量开展1:5万地球化学普查工作.通过方法试验确定土壤测量采样密度为4～12点/km2,采样粒度为-4～+80目,采样层位为残积层.经工作获得较为满意的异常圈定效果,发现了找矿线索.The Heyuan region of Daxinganling Mountains in Inner Mongolia is covered by forest and marsh, where the 1:50000 geochemical reconnaissance work should be done by ways of soil survey. The method trial has defined the sampling density for soil survey as 4 - 12 spot/km2. The grain size for samples is in the range of 4 to 80 per inch.The eluvium is the favorable layer for sampling. The result of anomaly delineation by this method is satisfied. And certain mineralization clues have been found .
