泥石流的危害性很大,为了减少损失必须进行危险度分析,再根据评价结果采取相应的防灾措施。泥石流发生因子都具有不确定性。模糊理论对处理不精确问题特别有效,因此选取了8项因子进行多级模糊综合评判,最后以实例进行验证,取得了预期的效果,可作为预警参考使用。 Debris flow hazards are great, in order to reduce losses must be carried out risk analysis, and then based on the evaluation results to take appropriate disaster prevention measures. Debris flow generation factors are uncertain. Fuzzy theory is particularly effective in dealing with inaccurate problems. Therefore, eight factors are selected to carry out multi-level fuzzy comprehensive evaluation. Finally, an example is used to verify the results. The expected results are achieved and can be used as an early warning reference.
