[Objective] To explore the technology and method of the analysis and evaluation of debris flow disaster in the west Kunlun area of Xinjiang Region. [Methods] Taking Maeryang area of Xinjiang Region as the research area

and studied the characteristics of the geological environment in the region with the collected previous data and other information sources. Through interpretation of ETM+ images on the study area

the debris flow sites were identified. The terrain and topographic characteristics were also analyzed with DEM data. [Results] The appropriate indicators were selected for debris flow hazard assessment

and an index system was developed for risk assessment. The general risk area

medium risk area

high-risk area and extremely dangerous area were 31.69 km2

40.70 km2

38.31 km2 and 25.83 km2

with an area ratio of 23.21%

29.81%

28.06% and 19.92%

respectively. [Conclusion] Extremely and high danger zone in the study area account for 47.98% of the total area

mainly distribute in the northwest and central regions

and which is highly dangerous geologic disaster occurrence areas.
