摘要
“3S”技术与地学的结合,对传统地貌制图的编绘方法必然产生较大影响。遥感影像不仅作为地面调查的重要辅助手段,而且是一种可以根据需要缩放到所需比例尺的重要数据源;各种数据源的参考数据如地形图、植被图、地质图、土地资源图等均可以数字的方式在GIS环境中集成、叠加与运算,从而改变了地貌制图依赖于地形图进行多次综合概括的制图方式,使基于多源数据的遥感地貌信息定量解译成为可能。以青藏高原昌都幅遥感地貌解译为例,探讨不同类型的数据在山地地貌解译过程中的使用方式和对地貌判读的作用,并在此基础上总结基于多源数据的遥感地貌解译方法,为全国1∶100万地貌遥感解译和地貌信息系统的建立奠定基础。
With the further combination of ＂3S＂ with geosciences, it has great influence on mapping methods of traditional geomorphologic cartography. Firstly, remote sensing data is not only an important assistant measure for ground survey, but also an important data source which can be zoom in or zoom out to certain scales according to needs, which changes the data sources of traditional geomorphological cartography. Secondly, data with different sources such as relief map （DEM）, vegetation map, geological map and remote sensing data can be integrated, overlapped and calculated in GIS environment, and this totally changes the mapping methods of traditional geomorphological cartography which was depended on generalization from topographical map by several times and makes it possible for quantitative interpretation of geomorphological information based on multiple-data-sources. In order to establish a set of methods for geomorphological interpretation on scale 1： 1,000,000, this paper discussed the ways and the functions of different data for landform interpretation and the interpretation methods of geomorphological information based on multiple-data-sources. Changdu Sheet in Tibet Plateau was our experiment area.
