摘要
应用物元理论,提出了滑坡灾害风险预测物元综合评判的基本流程,并以危险性预测为例讨论了物元集合的建立、等级关联度的确定等关键技术问题,建立了滑坡灾害风险综合评判的物元模型;运用物元模型与GIS技术相结合,对三峡水库蓄水条件下巴东新县城的滑坡灾害进行了危险性、易损性、风险性综合预测研究,证明了物元模型在区域滑坡灾害风险预测中的应用可行性;同时指出了所存在的问题及可能解决的途径。
The basic flow chart of Matter-Element multidisciplinary assessment for landslide hazard risk assessment is put forward by means of the Matter-Element theory.Some key technical problems are discussed,such as matter-element set building,grade dependent degree calculating and so on.Also this paper established the Matter-Element model for the zonation evaluation of the landslide hazard risk.Matter-Element model and GIS technology are applied to carry out the landslide hazard comprehensive assessment of new Badong County Based on hazard evaluating and vulnerability estimating,the landslide risk after the construction of Three Gorges reservoir is assessed in the study area.Finally the paper has proved the applicability of Matter-Element model in landslide hazard risk assessment.At the same time,it has pointed out the existing questions and the possible solutions.
