内蒙古黄岗梁——白音诺土壤地球化学方法探讨

Probe into the Geochemical Methods for the Huanggangliang-Baiyinnuo Soil in Inner Mongolia

根据内蒙古黄岗梁—白音诺半干旱区的特点,从研究风成沙对本区土壤地球化学影响入手,进行了土壤的层位及粒度的研究,以确定该区在野外实际工作中土壤地球化学勘查方法所采取的粒级区间和层位。结果表明,土壤测量应截取-5mm～+0.45mm粒级,层位为c层样品,可有效排除风沙的干扰。

On the basis of the features of Huanggangliang-Baiyinnuo arid zone in Inner Mongolia,this paper researches on the horizons and granularities of the soil starting from the research on the influence of the wind sand on the soil Geochemical nature of this zone in order to determine the granularity interval and horizon adopted in real field soil Geochemical reconnaissance in this zone. The results show that the soil measurement should intercept the granularities of -5 mm～+0.45 mm, adopt the soil specimens of C horizon, which can effectively eliminate the interference of the sand storm.
