The application of GIS to the forecast and evaluation in the regional landslide can provide scientific basis for
the regional geological environment management and the geological disaster assessment, can integrate the scattered data
to share each other, and can improve data value. Its powerful interface function library provides a good tool for the professional
GIS design and development. This study carried out rapid modeling, efficient calculation and strong visibility in
the slope evaluation by highly fusing Geographical Information Systems (GIS) and slope engineering together and combining
Supermap GIS with ANSYS, which are representative software in their fields. Furthermore, the system of slope
stability analysis and evaluation was established by quadric developing, which made a bridge between the fields of GIS
and slope stability assessment.
