内蒙古东乌旗草原覆盖区遥感构造信息提取

TECTONIC INFORMATION EXTRACT IN THE DONG UJIMQIN COUNTY GRASSLAND DISTRICT OF INNER MONGOLIA

利用遥感技术在内蒙古东乌旗草原覆盖区进行构造信息提取,在GIS平台下结合地质及物探资料,对该区构造进行解译研究,重新厘定了该区的构造格局,为区内新一轮国土资源大调查提供了一些有参考价值的信息。

By means of remote sensing technique, tectonic information was extracted from LANDSAT ETM+ images processing and geology and geo-physical exploration information in Dong Ujimqin County, Inner Mongolia. Due to the complicated terrain surface mainly covered by dense vegetation in the study region, the LANDSAT ETM+ images were carefully selected and technically processed to enhance the structure. On the platform of GIS, the tectonic framework was redefined by combining the tectonic information extracted from remote sensing images and the geology information and the geo-physical exploration information. The results obtained might provide valuable information to a new turn of the Great Territory Investigation.
