沙尘暴严重程度的模糊综合评判——以内蒙古地区为例

Fuzzy Evaluations for the Severity of Sand Storm——Taking the Inner Mongolia Area as an Example

采用模糊综合评判的方法对内蒙古地区沙尘暴严重程度进行量化评判。筛选出对沙尘暴的发生影响较大的三类九种因素,这三类因素是土壤岩石因素、植被降水因素、大气因素。结果表明,评判结果与大众感受相符,可为沙尘暴问题的预测与分析提供初步的数学模型。

The severity of Sand Storm in Inner Mongolia was studied quantitatively by use of fuzz- y evaluations. The three classes of factors which include nine categories were screened. The three classes of factors are soil rock factors, vegetation precipitation factors and atmospheric fac- tors, which have greater effect on sand storm. The conclusion worked out is consistent with the public feeling and provides a preliminary mathematics model for analysis and forecast of sand storm.
