【摘要】 依托GIS与RS技术,以广西省都安瑶族自治县为研究载体,采用TM影像为背景资料,辅以地形图、土地利用图、地质图、土壤图以及GPS实测数据库等相关资料综合分析,建立石漠化分级的遥感影像解译指标体系,生成都安县石漠化分级分布图和数字化土壤类型图;运用GIS空间分析功能,定量探讨不同级别石漠化与土壤类型之间的空间相互关系。更多还原

【Abstract】 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, from the viewpoint of spatial correlation, is proposed.更多还原
