摘要
以清平乡11条泥石流沟为依据,分析其泥石流形成条件,采用模糊综合评判法对其危险性进行综合评判。选取7个因子作为泥石流危险度评价的主要关联因子,利用灰色关联分析法确定其权重,建立泥石流危险性评价模型,对每条泥石流沟作出危险性评价。评价结果与实际情况基本相符,表明采用模糊综合评判法评价泥石流危险性是可行的。
Depending on the 11 debris flow gullies in Qingping Town, the forming conditions of the debris flow were analyzed, and then with fuzzy comprehensive evaluation, the hazard was assessed in such manner that at first, 7 factors were selected as the main correlation factors for the hazard assessment of debris flow; then, by gray correlation analysis, the weight of the factors was confirmed; at last, the model was established to assess the hazard of each debris flow gully. The assessment result is in conformity with the actual situation basically, showing that fuzzy comprehensive evaluation is feasible for hazard assessment of debris flow.
