6.5 Conclusions
Landslide is a kind of widespread geologic hazard in the rural area of the Loess
Plateau, China. Since the 1980s, 53 fatal landslides have occurred, causing 717
deaths. Landslide also accounts for a considerable proportion of soil erosion in the
upper and middle reaches of the Yellow River. In some catchments of the Loess
Plateau, the contribution of landslide erosion to the total erosion was up to 50%.
Among the fatal landslides on the Loess Plateau since the 1980s, about 40%
were triggered by rainfall. Landslides also result from several other factors such as
human activities, freeze-thaw and earthquake, which accounted for 36, 23 and 1%,
respectively. Compared with the earthquake on the Loess Plateau, human activities
and the freeze-thaw factor were found to be more significant in triggering a landslide.
Moreover, human activities had an increasing trend in the impact of the landslide.
Due to the frequent occurrence of landslide disasters, effective measures advocated
by the local government are urgently desired to control landslide hazards in the area.
