摘　　要：近年来,滑坡灾害频繁发生且极大地危害着人类的生产生活,因此,如何快速有效地进行滑坡灾害危险性分析与评价,进而为滑坡的预测、预报及风险管理服务是一个亟待解决的问题。以莆田市为例,通过将地学信息图谱应用到滑坡灾害危险性评价中,构建莆田市高程、岩性、坡度、坡向影响因子信息图谱,并在此基础上得出莆田市滑坡灾害危险性评价信息图谱,以一系列的图谱直观地反映了莆田市滑坡发生的机制及滑坡危险性空间分布情况,反演了莆田市滑坡发生的时空变化规律,为滑坡灾害预测提供了矢量化的图形信息。Landslides occur more and more frequently in recent years and threaten the production and human life seriously.So,it becomes an urgent task to analyze and evaluate landslide hazards fast and effectively for serving landslide prediction and risk management.Taking Putian city as an example,by applying the geo-informatics map to landslide hazard evaluation,the information maps of landslide causative factors,such as elevation,lithology,terrain slope and aspect are worked out,on the basis of which,the landslide hazard evaluation information maps are obtained.The series of maps not only reflect the landslide mechanism and spatial distribution,but also inverse the rule of temporal-spatial change of landslides in Putian city.It provides vector graphic information for landslide prediction.
