Abstract：The spatial distribution,development characteristics,formation conditions and development pattern of geological disasters constitute the foundation of regional disaster prevention, mitigation and dynamic monitoring. As a rapid,economic and accurate survey technology,remote sensing technology has been widely applied to geological disaster investigation. In this paper,based on the findings of the project of serious geological disasters investigation using remote sensing technology in the Himalayas of China,the authors introduced the methods of remote sensing technology for debris flow investigation in such aspects as remote sensing data and remote sensing interpretation keys. Using GIS spatial analysis methods,the authors analyzed distribution characteristics of debris flow in the study area. In addition, the information of the development characteristics of the debris flow scale,water type,shape and length,gully slope,and the direction of movement was extracted. Based on the quantitative statistic indexes of large-scale debris flow under different backgrounds of the rock group of engineering geology,geological structure,topography,land use types,vegetation cover and climate,the authors summarized the basic condition of the debris flow in this study area and its relationship with the influencing factors. The research results will provide the essential data and scientific decision-making for disaster prevention and mitigation in the Himalayas of China.
