AbstractPeople in mountainous regions are likely to settle on alluvial fans that are primarily composed of accumulated debris flow sediment. Despite their many agricultural benefits, these areas are also highly vulnerable to debris flow hazards. Dabaini catchment, in the Xiaojiang basin, Yunnan province, was chosen as a study area to monitor the long-term change of alluvial fans as well as the corresponding influencing factors. Landsat images of the area from 1987 to 2013 and an object-oriented classification method were used to interpret the debris flow fans in each of these years. Their evolution characteristics revealed that (1) the hazard area of debris flow fans has shrunk during the recent 30 years; (2) the debris flow alluvial fans in Dabaini are affected by the size of the debris flows; (3) less precipitation, sediment source, human activities and higher vegetation are the main factors that contribute to the changes of volume in the alluvial fan in recent years.
