摘要
针对泥石流发生的复杂性和不确定性,运用模糊数学综合评价的方法,从人类活动、地质、地形和气象水文条件4个总目标和19个子目标,建立了泥石流易发性模糊综合评价模型。确定了目标因素等级及权重,对邱家沟、天须沟和长坡沟泥石流易发性进行了综合评价。结果表明,邱家沟泥石流易发性最大,天须沟次之,长坡沟最小。
In light of the complex uncertainty of the debris flows, fuzzy mathematics is used to make a comprehensive evalua lion. Haman activities, geological, topographical and climate conditions are analyzed in establishing a fuzzy mathematics evalua lion model. Factors are classified and their weights are dcfined. The studies on Qiujiagou, Tianxugou, and Changpogou gullies show that, in terms of debris-flow susceptibility, Qiujiagou comes first, Tianxugou second, and Changpogou third.
