Abstract:

The situation of geo-hazards is severe in China. The status, trend and problem of geo-hazards prevention are discussed in this paper. On the one hand, in the view of geo-hazards prevention, the basis status of geo-hazards in China is discussed, and the prevention system of geo-hazards in China is studied. Then, with a typical debris flow, occurring in August 8， 2010， in Zhouqu County, Gansu Province， in the southwestern  China, some problem and deficiency of geo-hazards prevention are discussed. On the other hand, in the view of geo-environment development, evaluation frame and system of regional geo-environment sustainable development are constructed, and geo-environment safety management is advanced. Finally, conclusions are as following: we should escape from the habitual thought of the single engineering geological evaluation or the single geo-hazards prevention. The protection of geo-environment and prevention of geo-hazards should be organic integrated to ease geo-hazards.

Key words: geo-hazards, geo-environment, prevention system, evaluation system, sustainable development
