The sand-sliding slope is a common geo-hazard in the mountain areas of western China,it belongs to one special type of the generalized definition of landslide. In South-East Tibet,the sand-sliding slope is characterized by wide distribution and serious damage. Development of the typical sand-sliding slope usually consists of three processes including the generation of debris and sand,sliding and deposit at the foot of slope. During the development of the sand-sliding slope,the dominant factors are composed not only of the gravitational force but also of the physical weathering. The sand-sliding slope is the productions under the specific environmental conditions,in research area,most of the sand-sliding slope occurred from the 6 ka BP,and the time represents the rainfall decreases in the monsoon region since the early Holocene,which is recorded by the Chinese stalagmite,as well as it responds to the global climate change. According to the mode of sand source formation,the development position of geomorphy and the characteristics of sliding sand,the sand-sliding slope could be classified into two types including the primitive type and the self-reorganization type. Some measures such as avoidance,mucking,sand draining, sand retaining etc. should be taken for the primitive type,as for the self-reorganization type,the effective measures are made up of control engineering in sand source area,sand consolidating and sand retaining and so on.
