| 摘 要： | 滑坡灾害空间预测经历了从定性-半定量-定量、从确定性-非确定性-概率论的发展过程,其中预测模型的建立、预测方法的选取是滑坡空间预测的核心过程,关系到预测结果的最终确定.讨论了信息量模型、信息-物元模型、信息-神经网络模型的预测流程和关键技术问题,将这3种非确定性数学模型运用于万州安乐寺古滑坡区的滑坡危险性预测中,并对3种模型的预测结果进行了对比分析,指出3种预测数学模型的优劣及其应用中需注意的问题,对比研究表明3种模型均不失为滑坡空间预测中较为有效的数学模型.

| Abstract: | Landslide spatial assessment develops from qualitative, semi-quantitative to quantitative, and from certainty analysis, uncertainty analysis to probability analysis. In the process, building assessment model and choosing assessment method are the key steps, which are responsible for the veracity of the result. This paper discusses the flow chart and some key problems about the information model, information-matter element model and information-ANN model. The three models and GIS technology are applied to the landslide hazard susceptibility assessment of Anlesi paleo-landslide in Wanzou City of the Three-Gorge Reservoir. The paper also presents the advantage and disadvantage as well as their differences and the existing problems of the three models by comparing the results. It is concluded that the three models are the effective mathematics models for landslide spatial assessment. |
