Abstract: Locating in the west of Mt.Liupan in Ningxia,the Xiji region is the area where 9-10 degreeearthquake occurred in 1920.There is a great variety of slide hazard-induced landforms,includingbedding slide types on the bottom or in the middle of loess layer and longer-belts along loess ridge onright bank of the Hulu River.Although epicentral intensity of the earthquake was about 11 12 degree,the disastrous characters of landslides here were the most serious in comparison with all otherintensity areas.Based on the systematic description of distribution of slide hazard-induced 1andforms in the Xijiregion,the paper discusses deeply the formative mechanism of the landslide resultant forms.The result of study indicated that the origin of those was not only controlled under earthquake intensity butalso influenced by physical environment,such as natural property of loess,geologic structure,geomorphic texture,regional tectonic movement and so on.Therefore the scale and distribution of somekinds of ground deformations,e.g,landslide landforms,may be a bit of unconformity in contactwith its intensity degree within the meizoseismal area.
