中文摘要：

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。

英文摘要：

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.
