本文提出了基于GIS的滑坡灾害风险预测系统的流程图。运用滑坡危险性评价模型，利用GIS技术在图像处理和空间分析方面的优势，建立了巴东县新县城滑坡危险性评价系统。该系统主要由信息管理子系统、灾害评估子系统、易损性评价子系统和风险预测子系统四个子系统组成。该系统采集并保存了大量的相关数据。结合物元模型、BP神经网络模型等技术预测模型，实现了滑坡危险性评价和易损性评价。最后编制了研究区滑坡灾害风险图。该系统为三峡库区库区各分区滑坡灾害信息管理和风险预测提供了一种有效的途径。评价结果可为国家规划和水库移民工程提供依据和保证。
In this paper, based on GIS, the flow chart of landslide hazard risk prediction system is put forward. By using the landslide risk evaluating model and the advantages of GIS technology in image processing and space-analysis, the relative landslide hazard and risk evaluating system of the new county site of Badong is built up. The system is mainly consisted of four subsystems: information management subsystem, hazard assessment subsystem, vulnerability evaluation subsystem and risk prediction subsystem. Large quantity of relative data is collected and saved in this system. Combined with technical predict models, such as Mmatter-Element model and BP model, landslide hazard assessment and vulnerability evaluation are realized. At last the landslide hazard risk map of the study area is made out. This system provides an effective way for the landslide hazard information management and risk prediction of each district in of reservoir in the reservoir area of the Three Gorge Project. The result of the assessment can be a gist and ensure for the country planning and the reservoir immigration project.
