中文摘要	近红外分析技术已经广泛应用于岩石分析中,方法简单、快速、有效,可以在短期内分析较多样品,适合应用于区域地质物质成分的分析。近红外光谱中不同矿物分子会表现出不同的峰值特征,故对层土壤进行近红外分析,可以较精确的获得土壤中矿物成分、含水量、矿物结晶程度等信息。通过分析河套平原土壤样品,推测出其矿物成分、含水量、晶体结晶程度等,结合当地气候特征和地质环境,推测其物质来源和矿物形成环境,不仅完善了当地的地质特征,还对河套地区土壤的成因机制的研究有重要意义。实验结果表明,河套平原表层土壤的矿物主要由高岭石、蒙脱石、伊利石、白云母等蚀变矿物组成,从而推测其来源为阴山山脉中酸性岩体,同时提出阴山山脉在气候方面对河套平原土壤形成也有重要影响,内蒙古地区虽然为大陆性干旱气候,但降水量充足,且阴山山脉南北两侧的年平均降水量差异巨大,阴山山脉南部的年平均降水量较北部大,保证了河套平原湿润的环境,有利于沉积物充分蚀变,这些均为土壤成因机制的完善提出了新的研究方向。
英文摘要	The technology of near infrared spectrum, marked by its convenience and effectiveness, which has been applied extensively in lithological analysis, is suitable for component analysis of regional geology, due to its superiority in analyzing numerous samples in a relatively short time. Since different mineral molecule peaks will show different characters when being analyzed in the near infrared spectrum, we can acquire the information about the mineral composition, water content, mineral crystallinity and etc. In this passage, the soil from the surface of Hetao Plain has been analyzed, and in this case, we can obtain the information about the mineral composition, water content, mineral crystallinity and etc. Referring the features of local environment and climate, we could surmise the source of the minerals in soil and the environment where they formed. The result not only consummates the geological characterization of Hetao area, but also has great significance revealing mechanism of soil-formation in Hetao area. The result shows that the soil from surface of Hetao Plain is mainly composed by altered minerals, such as kaolinite, smectite, ledikite, muscovite etc, and is presumed to be from acidic rock mass of the Yinshan mountains. The passage also indicates that the Yinshan mountains have great impact on the formation of the soil on Hetao Plain in the aspect of climate, for example, though the climate of inner Mongolia is continental arid climate, enough rainfall and the substantial differences in mean annual precipitation ensure the relatively moist environment in this area, and make the sediments altered adequately, proposing new aspects about exploring the mechanism of the soil-formation in Hetao area.
