Abstract: Debris flow is due to the convergence of a lot of water, carries special flood mud formed in a short time. The debris flow mainly developed in four areas in our county, the south eastern of Tibetan Plateau, the Sichuan-Yunnan mountains, the Loess Plateau and the north and northeast mountains. Description of debris flow generated by the hazardous conditions and to further understand the importance of monitoring and early warning of debris flow. Combining the domestic and abroad over the years of monitoring and early warning of debris flow research experience, This paper reviewed and summarized the research of debris flow monitoring and early warning at home. And abroad so far through debris flow monitoring(solid materials, water condition and debris flow movement characters etc.) ，debris flow critical rainfall model and debris flow early warning technology method etc. Then the problem of low early warning rate of debris flow available at present time is analyzed. And last the advances on questions need to be solved are posed. The further research trend of debris flow monitoring and early warning is given, that is to introduce the researched work so far and promote the development of disaster prevention.
