摘　　要：Earth-fissure in Linfen city is dominated by many factors. Everyfactor is analyzed in detail and each coverage of them is established. After that, reciprocal relationship between them is determined by using AHP method. With the strong spatial-operation function of GIS, the advanced GIS models of earth-fissure simulation and multi-source forecast are built. On the basis of this, a satisfying prediction has provided extremely important science bases for the city future plans.Earth-fissure in Linfen city is dominated by many factors.
