This paper presents a GIS-based analysis of remotely sensed(RS) data for the Du'an Yao Autonomous County of Guangxi Zhuang Autonomous Region
including TM image background data and landform
land use
soil
geological and GPS database data. An RS image integration index system for rocky desertification grades are established. A rocky desertification grade map and a digital soil map of Du'an County are presented. Finally
a connection between different degrees of rocky desertification and soil type
