摘　　要：三峡库区滑坡灾害广泛发育,其稳定性受土地利用变化等人类工程活动的影响。采用数据挖掘技术研究库区土地利用变化对滑坡稳定性的影响及其规律,利用三个时相的遥感影像得到实验区滑坡面上两个时段间的土地利用变化监测图,用Apriori算法挖掘出滑坡稳定性与土地利用变化类型之间的强规则,用马尔可夫链模型预测滑坡面上土地利用的变化趋势,将预测结果用于对滑坡稳定性发展的分析评估。通过实验分析,所采用的方法可用于预测滑坡稳定性变化趋势,为滑坡灾害的监测预警提供决策支持。The Three Gorges Reservoir area has a frequent occurrence of landslides. The stability of landslide is influenced by land use and other factors. The relationship between stability of landslide and change type of land use is discussed by data min- ing techniques. The images of the change of land use in two periods are concluded by interpreting remote sense images of the study area in three different times. Strong rules between the stability of landslides and the change type of land use are mined by using Apriori algorithm. The change trend of land use is predicted by using Markov chain mode. The predict results are used for the stability analysis of landslides. Through experimental analysis, the method proposed in this paper can be used in predicting the stability trend of landslides and taking the decision-making support for the monitoring and predicting of landslide hazard.
