摘要

 
    

Combined with some important issues concerning landslide environmental factors, the typical spatial data sets of landslide inventory were analysed. Based on spatial data sets of landslide inventory discussed above, earthquake-induced landslides in the Yingxiu meizoseismal area of 5.12 Wenchuan earthquake were inventoried by use of GRASS GIS. From the earthquake-induced landslide inventory, the landslide types, distributions, geometry information and correlation between landslide probability density and landslide area were extracted. It can be concluded from the earthquake-induced landslide inventory that landslide inventory in a large region can be made rapidly.
