| Abstract: | In order to prevent and reduce the expense of lives and belongings of people which coming from landslide,on the basis of the demands of disaster prevention and mitigation,this paper analyzes the research actuality of the evaluation of natural disaster losses.On the basis of traditional method of evaluating disaster losses,and analyzes the method that has been existed of evaluating disaster losses and puts forward a quickly evaluating method of coast disaster losses based on multi-sources geographical spatial data.This paper discusses integrative analysis method of coast disaster for multi-sources geographical spatial data.The method was demonstrated in Yanhua factory in Wushan,the Yangtse River Gerges,and summarizes the method of evaluating model of coast disaster losses.Finally,a comparison between two results of model calculational and traditional investigation was made,and the method of model calculation was demonstrated in its feasibility and applicability in multi-sources geographical spatial data.Depending on softwares such as ArcGIS,Oracle and ArcObjects,the paper carries out the method of establishing database based on multi-sources and the model of loss evaluation. |
