摘　　要：在森林沼泽景观区中低山亚景观条件下,通过4个研究区的试点工作认为:①以找寻小型以上规模矿床为目的的区域化探异常查证工作方法,以水系沉积物加密测量为佳,采样粒级-10^+60目,采样密度3~4点/km2。②采用B层残坡积土壤测量可以达到同样的目的;采样粒级-20目,采样密度4点/km2左右;采样布局为沿山脚和山脊的不规则测网。③在倒石堆发育区,可以采用采样密度6~7点/km2渗湿土测量方法进行异常追踪。④泥炭测量难以获得比较全面和客观的测区找矿前景信息,在区域化探异常追踪阶段最好不要选用。The follow-up methods for regional geochemical anomalies were studied in four areas with the forest-swamp middle-low mountain landscape. Some conclusions were summarized： （1） Stream sediment survey of -10 - ＋ 60 mesh with sampling density of 3 - 4 samples/km^2 is a good method in search for small-large sized deposits; （2） pedogeochemical method collecting layer-B residual and slope materials of - 20 mesh is also a good method, which uses an irregular network with sampling density of about 4 samples/km^2 along piedmont and ridge; （3） soaked soil survey with 6 -7 samples/km^2 for follow-up in talus areas can be effectively used; （4） peat survey method should not be applied because it only provides poor information of mineralization.
