Other Abstract



Based on a large number of data of geological disasters field survey and multisource interpretation of remote sensing images, we obtained 899 geological disaster sites. We firstly selected 9 influence factors including land- form, geology, earthquake, meteorohydrology and mankind activity,and then conducted statistic analysis of spatial distribution law of geological disasters and each factor by use of GIS technology. Assessment and zoning of secondary disaster hazard were carried out on the basis of K-prototypes clustering analysis and maximum likelihood classification. Resuts show that the geological disasters in disastrous area are not same for different kinds of disaster, and present discontinuous concentric distribution. Among the disaster hazard, medium, high and extreme high hazard are dominant ones, and they account for 35.10%, 21.67% and 24.38% respectively, extreme low and low hazard area account for 18.85%. There is a better positive correlation between spatial distribution of disaster site and hazard class of disaster. This verifies directly zoning results of the hazard.
