Analysis of basic characteristics and deformation mechanism of loess potential landslide of terrace: Taking loess hilly region in southern Ningxia as an example
The Yellow River Basin has active geological structure, rapid geomorphic evolution and significant regional differentiation of climate, resulting in many types of major disasters in the basin, wide distribution and strong paroxysm. Taking the Loess Hilly Region in the south of Ningxia as the researc...

| description | The Yellow River Basin has active geological structure, rapid geomorphic evolution and significant regional differentiation of climate, resulting in many types of major disasters in the basin, wide distribution and strong paroxysm. Taking the Loess Hilly Region in the south of Ningxia as the research area, this paper introduces the concept of loess potential landslide of terrace. By combining historical data collection, remote sensing image interpretation, field investigation and mathematical statistics, it analyzes the development characteristics and distribution rules of loess potential landslide of terrace, and analyzes its formation reasons. The results show that: （1）There are 26 loess potential landslide of terrace in the study area, which are mainly distributed in the Quaternary loess, with a larger number of medium and long slopes, mainly loess potential landslide of terrace of shallow and middle-level, and the scale is mainly small. （2）The loess potential landslide of terrace are mainly distributed in loess hilly areas and large undulating mountain areas, the elevation interval of 1 800~2 000 m, and the slope direction is southeast, South and southwest in space; It is mainly distributed in rainy season or seismicity period in time. （3）Topography, stratum lithologic, rainfall, surface water and human engineering activities are the main factors for the loess potential landslide of terrace. The research results have guiding and reference significance for the risk identification and risk management of loess potential landslide of terrace in the Loess Hilly Region in Southern Ningxia and the Yellow River Basin. |
