| 摘 要： | 针对洮河谷地(岷县段)所处的地质环境和条件的多样性、变异性、复杂性,泥石流沟谷从形成、发展至消亡受到了很多因素的影响,从而形成了这样一个较为复杂的泥石流灾害"模糊"巨系统,本文将模糊数学理论引入泥石流危险度的评价研究中。运用模糊综合评判法,参考国内刘希林、宫雪、陈伟等的相关文献,最后确定了沟谷纵比降、流域相对高差、泥沙沿程长度补给比、冲淤变幅、植被覆盖率等8个因素作为泥石流危险性评判因子,对岷县洮河流域21条泥石流沟做了单沟危险性评价。

| Abstract: | According to the diversity,variability,complexity of the geological environment and conditions in the Taohe river valley,Min County,debris flow gully formed a more complicated disaster fuzzy system from the formation and development to the disappearance by a lot of factors influence.This paper introduced fuzzy mathematics theory into the risk evaluation of the debris flows.This paper used fuzzy comprehensive evaluation method developed by Liu Xilin,Gongxue,and Chen Wei,and selected eight risk factors such a... |
