Paper Title:
Landslide Hazard Zoning for Highway in China Base on Remote Sensing and GIS
  Abstract

Eight factors such as slope, incision density, incision depth, average annual rainfall, average annual >50mm rainfall days, soil types, river density, and vegetation cover ratio were used to quantify the Landslide Predict Index for highway in China. Using digital elevation data, rainfall data, thematic map of soil and river, remote sensing data of Spot/vegetation NVDI, these factors were calculated base on spatial analysis, hydrologic analysis, geostatistical analysis supported by ArcInfo9 software. The factors weights were confirmed by applying of expert estimation. The calculation results indicate that a highly spatial heterogeneity exists in the landslide Predict index for highway in China. Considering the maximum and minimum value of the index, the Landslide Predict Index for highway is divided into five levels. The landslide hazard zoning for highway is carried out base on the Landslide Predict Index mainly, then the landslide hazard zoning map for highway in China is formed.
