Abstract: Debris flows occur extensively over the western China and cause serious property lose and casualties. It is established that Tibet plateau upheaval, intensive tectonic movement, complicated geology, steep topography and frequent concentrated rainstorm, all of them contribute to the magnitude and scale of debris flow occurrences. As one of the typical geo-hazards, debris flows often behave as destroying villages, ruining highway, occupying farmland and reservoir, and pose a danger for nearby inhabitants, thereby considerably harm the local society safe and economy development in the mountainous area. It is always regarded as a key factor in blocking regional economic development. Chinese Government in the past play an important role in the debris flow control around the western mountainous area. Research on debris flow was encouraged and supported financially by the Government. Therefore, a series of technologies for debris flow control have been developed and evolved into a unique Chinese manner of debris flow control, which made a great success in geohazards control in the past. This paper mainly includes following topics:

1)      Debris flow activity and it ‘s harm in the western China;

2)      Integrated system of debris flow prevention and mitigation;

3)      Monitoring and alarming technology for debris flow;

4)      Control technology of debris flow;

5)      Contribution to development of a mountain area due to effective debris flow control

6)      Conclusion.

 

Key words: debris flow; geohazards control; mountain area development; the western China
