| 中文摘要:内蒙古南部砒砂岩分布地区的岩土侵蚀非常强烈，外界原因是当地的气候自然条件十分恶劣，而内在根源是当地有大量易于侵蚀的物质-砒砂岩。本文从矿物成分、化学成分、岩性组合、颗粒密度、岩体构造和工程性质等方面对砒砂岩易于侵蚀的内在原因进行了初步解析。 |

| The Internal Cause of the Erosion in "Pisha" Sandstone Area, Southern Inner Mongolia |

| Abstract:The rock and soil erosion in Pisha sandstone area of southern Inner Mongolia has been very serious. Its external causes are local atrocious climate and awful nature conditions, whereas its internal cause seems to be the existence of abundant erodible materials—“Pisha” sandstone. The intrinsic cause for the erosion of “Pisha” sandstone has been tentatively analyzed in this paper in the light of minerals, chemical compositions, rock associations, grain size distribution, structure characterstics and engineering features. |
