Landslide susceptibility mapping based on GIS modle on Shicheng Jiangxi province, china
[摘要] A GIS model-information index model was presented for landslide susceptibility mapping on Shicheng, Jiangxi province, China.140 landslides were identified from SPOT6 fusion image with 1.5 meters resolution, and they were verified by field investigation. Application of the information index model showed that the landslides more likely occur in areas nearby the road, the river and the lower vegetation covery. The high elevation accuracy of 71% was reached using a receiver operating characteristic (ROC). The result indicates that the northeast and parts of the south of Shicheng County are highly susceptible to damages from landslides, which provides useful information for disaster management and decision making.
