英文摘要	: Debris now hazard assessment is a basic work of hazard monitoring, forecast, alleviation and control. Seven factors, including the maximum volume of once now (L1), occurrence frequency of debris flow (L2), watershed area (S1), main channel length (S2), watershed relative height difference (S3), valley incision density (S6) and the length ratio of sediment supplement (S9) are chosen as evaluation factors of debris flow hazard degree. Using support vector machine (SVM) theory, 259 basic data of 37 debris flow, channels in Yunnan Province are selected as learning samples in this study, then a kind of debris now hazard assessment model based on SVM is produced. First instance applications gave encouraging results. After Cross Validation test, accuracy of this model came to 70.00%. Through verifying 7 groups of test data, classification accuracy came to 85.71%.. The model shows that it has the advantages of best generation, convenience and high precision. SVM is regarded as a broadly applicative tool in debris flow hazard assessment.
