摘要
利用层次分析法,结合专家评分模型,构建了滑坡预警评价指标体系。在GIS技术的支持下,开发出滑坡预警分析系统。采用该系统不但能预测滑坡灾害的空间发展趋势,而且还可反映出某一时段内其发生发展态势。文中以河北省太行山地区为例,利用该系统,实现了该区的滑坡预警评价分析。其结果与实地滑坡分布规律存在很好的一致性。
For preventing and controlling landslide disaster, it is urgent to carry out regional early warning research of landslide hazard. Using grade model, expert analysis model and GIS technique, the table of affecting factor and a predictive system for landslide hazard evaluation has been developed. Using this software, we can prediction of a landslide hazard not only spatially but also temporarily. The implementation of the predictive system for landslide hazard evaluation is introduced, using GIS data of Hebei Mt. Taihang. The result is similar to the actual distribution of landslide hazard in Taihang, Hebei.
