摘要
集对分析方法的研究和应用对区域性滑坡预测具有较强的理论和实用意义。滑坡空间预测系统是一个受不确定因素影响较多的系统,而集对分析法能够很好地解决确定–不确定问题。将集对分析法引用到滑坡空间预测领域,以MAPGIS为操作平台,在对巴东县新城区滑坡灾害发育的地质背景、分布规律和发育特征进行统计分析的基础上,根据统计结果确定预测危险性等级评价标准,然后根据各预测单元的属性信息判别各预测单元指标等级,最后利用集对分析理论对各预测单元进行危险性等级预测。将所得空间预测图与已知滑坡分布图进行比较,认为结果可靠、方法可行,并得出联系度和集对势理论结合能够提高预测精度的结论。
Set pair analysis（SPA） method has a certain important theoretic significances and practical applications to landslide spatial prediction. Landslide prediction system is always affected by uncertainties that the SPA method can resolve based on the platform MAPGIS. Firstly, the geological setting in the new site of Badong County is counted and prediction units are divided. Secondly, risk assessment criteria are determined andindex levels ofall the predicted units are discriminated according to unit properties. Thirdly, risk level of each unit is predicted based on the SPA method. The results are considered feasible and reliable by comparing the predicted spatial distribution of landslide with the known landslide hazard map. It is shown that the contact degree and set pair potential theory can improve prediction accuracy.
