摘要
以吉林省江源县石人镇泥石流观测资料为背景,对该区泥石流形成及活动条件进行了较为全面的分析研究。提取出11项影响泥石流危险性的评价因子,利用灰色关联方法计算出评价因子间的关联度,并运用模糊数学综合评判法对石人镇13条泥石流沟进行了危险性评价,评价结果较为可信,对监测和整治泥石流具有较高的参考价值。
On the basis of the observation data of debris flows in Shiren town of JiangYuan county, JiLin province, the paper made a relatively comprehensive analysis of the factors of formation of debris flow and its activity, and then extracted 11 influ- ence factors of debris flows in the research area. After figuring out relative degree among those factors by gray correlation method, synthetical evaluating method of fuzzing mathematics is used to evaluate the risk of 13 debris flows in Shiren town, It is concluded that the evaluation result is credible and has much higher reference value for monitoring and regulating debris flow.
