AbstractThe area of the Cheng-hai valley, located in the centre of Yongsheng county Lijiang city Yunnan province, is an area with dense and frequent debris flow disasters due to unique geology, geomorphology and landform conditions. After in situ investigation and analyze the present data of these debris flows, we selected six factors, such as catchment areas, the length of main gully, average longitudinal slope of main gull, estimated outflow of every time, potential reserves of solid materials, percentage of grain diameter of solid materials above and beyond 200mm, as main factors for evaluating the risk degree of 6 chosen representative debris flows in the Cheng-hai valley. The multiple-factor comprehensive evaluation method is applied to evaluate the risk degree of debris flow and then the evaluation result shows a good correspond with the practical situation, i.e. this method has a valuable application foreground.
