Paper Title:
Activity Degree Evaluation of Glacial Debris Flow along International Karakorum Highway (KKH) Based on Fuzzy Theory
  Abstract

The area of international Karakorum Highway(KKH), is an area with dense and frequent glacial debris flow disasters due to unique geology, geomorphology and landform conditions,which connects northern Pakistan with northwestward China. After in situ investigation and analyze the present data of these glacier debris flow, by using the fuzzy evaluation method, we selected seven factors,such as occurrence frequency,catchment areas,volumes of alluvial fan,estimated outflow of every time,vegetation coverage, slope and altitude, as main factors for evaluating the activity degree of 8 chosen representative glacier debris flows along KKH. According to the evaluation results,which are showed a good correspond with the practical situation, it can conclude that the fuzzy evaluation method based on the fuzzy mathematics theory is an very effective evaluation method in dealing with glacial debris flow with lots of fuzzy factors,i.e. this method is available for evaluating the activity degree of glacier debris flows.
