摘要
The geohazards susceptibility is a main critical to decribe possibility of geohazards occurrence. Geohazards susceptibility evaluation is one of main tasks on the evaluation of regional geohazards risk. The quantitative or semi-quantitative evaluation on geohazard susceptibility using Analytical Hierarchy Process （AHP） was effective. Taking Chengxian County as an example, the paper introduced how to combine AHP with MapGIS for geohazards susceptibility evaluation.
