| 摘 要： | 利用遥感、G IS技术和其它分析手段,在“递进分析法”(AMFP)理论框架下,利用AHP模型评估各影响因子权重;选用综合指数评价模型求取潜势度、危险度及危害度等区域地质灾害评价指数;借助自建的灾害评价系统,实现了藏东林芝地区的区域性地质灾害预测评价及其可视化表达。研究结果表明:该方法评价结果较为合理;研究方法和试点区预警系统的建设实践对于区域性灾害的预测、预报和防止不仅具有理论意义,也具有重要的现实意义;将人类活动等影响因子量化,不仅缩小了预测区的范围,也突出了地质灾害对人类生存环境的影响。

| Abstract: | With the utilization of remote sensing,Geographical Information System(GIS) and other analytical tech-niques and on the basis of AMFP advanced for regional geological hazards warning study,the authors designed thejudgment matrix of Analytic Hierarchy Process(AHP) for working out the weight of assessment factor,and estab-lished the assessment model for geological hazards of the experimental region with the Comprehensive Index Model.Furthermore,by means of the geological hazard forecasting-warning systemof the experimental region,the results ofestimation of regional geo-hazards in Linzhi district were obtained.It is concluded that the results of this method arevaluable,that the research method put forward in this paper and the construction of the geological hazard forecasting-warning systemfor the research region have not only theoretical but also realistic significance in the forecasting andavoiding of geological hazards,and that the quantification of human activities can reduce the area of geological haz-ards forecast and make prominent the influence of geological hazards on the environment of human survival. |
