摘要The forecasting of landslide regions is very complicated. Fuzzy mathematics is applied in this article to form a fuzzy set of landslide regional forecast according to six factors: geomorphological conditions, lithologie characteristics, fracture structure, rainfall, earthquake and freeze-thaw action, which are chosen from many factors. To use functional exponents to show the functional extent of each factor on the landslide and decide the boundary of their subset critical values, an index system for forecasting landslide regions is set up. Landslides are not due to a single factor, but the combined effects of many factors. The forecasting of landslide regions expresses the integrated effect of fuzzy field using general mathematical formula.
