Abstract: | The socio-economic attribute of geo-hazard made us distinguish it from the traditional engineering geology study. It will
get more social benefit from the analysis of the geo-hazard in the socio-economic attribute. The hazard and the vulnerability
of the element controls the risk level of the regional geo-hazard. The risk analysis supported by GIS in geo-hazard study
is one of the most important directions. Based on the author’s studies in recent years, a risk analysis system of regional
geo-hazard (RiskAnly) has been developed on the basis of software MAPGIS. The paper introduces the train of system design,
the structure and the workflow of RiskAnly. As a case study, the paper also deals with the risk zonation of the regional landslide
hazard of China. |
