Abstract

Abstract: In this paper, the information content model and analytic hierarchy process are used to ana-lyze the disaster-prone geological conditions in Dantu District of Zhenjiang. Six evaluation factors, inclu.ding topographic relief, slope , engineering geological rock formation , geological structure, elevationand disaster point density, are selected to construct the evaluation system. By calculating the weightedinformation value of landslide and collapse geological disasters in Dantu District of Zhenjiang , the region-al geological disasters are divided into three levels of high , medium and low susceptibility. The calculat-ed results are in agreement with the actual survey results. This method provides scientific and objectivebasic data for geological hazard risk assessment in this region.

Key words: geological disasters, susceptibility assessment, low mountains and hills, information content model, analytic hierarchy process
