Application of information index model in landslide susceptibility mapping on Tonggu Jiangxi PROVINCE, China
IGARSS(2014)
摘要
The case study presents an information index model for landslide susceptibility mapping in Tonggu County, Jiangxi Province, China. More than 100 landslides were identified from the 2.5-m fused SPOT imagery, and about 60 percent of them were verified in field investigation. It is proved that the landslides are more likely to occur in granite areas, which are strongly weathered, and the areas close to faults. The high elevation accuracy of 75.6% was reached using a receiver operating characteristic (ROC). The result indicates that the south and parts of the northeast of Tonggu County, including Paipu-Yongning and Daduan-Guqiao Towns, are highly susceptible to damages from landslides.
