| Abstract: | 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. |
