Geomorphic hazards are harmful to the process and the phenomenon of surface movement of solid material from the Earth caused by outside forces generated, mainly soil erosion, landslides, desertification, landslides, avalanches and so on. With the rapid economic and social development of Yiliang County, the scale and intensity of human activity continues to increase, when geological disasters landslides, avalanches, mud and other debris have occurred, to a certain extent affected the sustained and healthy development of national economy and social stability Yiliang County, Therefore, prevention of geological disasters has become a very important job. To effectively prevent and control geological disasters, the maximum to avoid geological disasters and mitigate losses and protect peoples lives and property safety, promote coordinated social and economic development in recent years, active in Yiliang County of geological disaster monitoring, management and early warning preventio
