摘　　要：研究了土壤地球化学、土壤电导率和土壤元素活动态测量在内蒙古新巴尔虎右旗干旱-半干旱草原覆盖区的应用效果,圈出3处土壤地球化学综合异常,3处土壤电导率异常和1处土壤元素活动态综合异常,各异常在研究区对应的位置均有不同程度的套和。通过对比研究得出,利用土壤地球化学、土壤电导率和土壤元素活动态测量相结合的集成方法可以取得更好、更快的找矿效果;三种方法可以相互印证异常;土壤元素活动态测量,能够进一步强化异常。文中所用的方法和取得的一些认识,对内蒙古新巴尔虎右旗地区乃至其它草原覆盖区的地质找矿工作,具有一定的指导意义。The applied effect of soil geochemical survey,soil electro-conductivity survey and speciation analysis of elements survey in the grassland-covered area of Xinbarerhuyou county of Inner Mongolia were studied,portrayed 3 integrated soil geochemistry anomalies,3 soil electrical conductivity anomalies and 1 speciation analysis of elements integrated anomaly,the anomalies in the corresponding location of the study area have different overlap.Compared the different results of various methods,more better and more faster effect of prospecting could be achieved by using the compositive methods of soil geochemical survey,soil electro-conductivity survey and speciation analysis of elements;the three methods can mutual conf irm;the speciation analysis of elements survey could further strengthen the anomalies.The methods and conclusions in this paper have some guiding significance to the Geological prospecting in Xinbarerhuyou county of Inner Mongolia or other grassland-covered areas.
