| 本文研究了采用3"S"技术的单体滑坡灾害风险评估的原理,对单体滑坡的致灾因素和评估模型做了全面的界定.分析了光学遥感数据和干涉雷达技术在单体滑坡遥感信息提取的应用.对地理信息系统在评估过程中的应用进行了详细阐述,着重分析了数字高程模型、空间分析手段以及决策支持系统的作用. |
| 英文摘要: |
| This paper analyzed the theories of disaster risk assessment of single landslide using 3S technology,and studied briefly the hazard indexes and assessment models.In addition,optical RS and InSAR were used to extract the information on single landslide and also discuss the application of GIS,emphasizing the operations of DEM,spatial analsis and decision-making system in the assessment process. |
