滑坡灾害的多源数据分析与评估方法

Research on The Method of Analysis and Evaluation of Landslide Disaster Based on Multi-source Data

为有效地防治和减少滑坡地质灾害给人民生命财产造成的损失,本文根据防灾减灾决策的需求,分析了自然灾害损失评估的研究现状,进行了多源地理空间数据的滑坡灾害损失快速评估方法实验。文中采用多源地理空间信息获取及处理方法,对滑坡灾害进行了综合分析,并以三峡库区巫山县烟花厂滑坡灾害体实例进行验证,提出滑坡灾害损失评估模型方法。并利用模型计算与传统调查统计方法的结果,对其方法的可行性和适用性作了验证。

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.
