摘　　要：针对滑坡空间预测中遇到的问题,简述了滑坡空间预测的主要过程,首先介绍了栅格数据的准备过程,结合栅格数据的存储特点,提出了基于栅格数据的信息量模型预测流程。以三峡库区巴东新城区为例开展了滑坡空间预测,重点阐述了预测过程中关键技术,如基于栅格数据计算信息量的解决方案、预测因素状态的确定方法以及预测结果的分级方法,同时探讨了影响巴东新城区滑坡的重要因素,在此基础上开展了巴东新城区滑坡危险性预测并对预测结果进行了合理性分析。通过解决这些滑坡空间预测中的关键性问题,为滑坡空间预测提供了一个高效合理的解决办法。This paper first introduces the main process of spatial prediction for regional landslides with reference to the problems in the prediction.Firstly,the transaction process of raster data is presented.Then,the prediction flowchart of the information value model is brought forward combined with storage characteristics of raster data.Finally,a case study was made on the new town site of Badong in the Three Gorges Reservoir area for the spatial prediction of regional landslides based on raster data.The Key technologies of spatial prediction are depicted emphatically such as the solution to computing information value based on raster data,the determination of predictive factor state,and the classification method for predictive results which should be analyzed for rationality.The highly efficient and rational solution for landslides spatial prediction is provided by resolving these problems.
