ASTER影像在喀斯特石漠化遥感解译中的应用——以贵州省瓮安县为例

The application of ASTER image in remote sensing interpretation for karst rock desertification——With a special reference to Weng'an County of Guizhou

以2004年ASTER影像数据为信息源,在GPS野外调研和G IS软件支持下,对贵州省瓮安县喀斯特石漠化进行遥感解译,结果表明ASTER高光谱遥感与一般遥感影像相比能为对地观测提供更高质量的信息源,能较好地满足1∶5万石漠化成图的需要,为制定喀斯特石漠化综合防治规划提供依据。

With ASTER image in the year 2004 as data source, the paper, on the basis of fieldwork by GPS and software of GIS, carries on a remote sensing interpretation for karst rock desertification of Weng＇ an, Guizhou. The results show that ASTER remote sensing image, compared with other normal remote sensing images, can provide better source data for ground observation, which meets the needs of compiling the map of 1 ： 50 000 and establishing the integrated control programming for karst rock desertification.
