Application Research of Remote Sensing Technology in Regional Hydrogeological Survey

摘要

regional hydrogeological survey is groundwork for regional water resource development and utilization. In order to promote working efficiency and work cycle of traditional general survey, remote sensing technology is used to obtain the information of the region surveyed, such as landscape, Quaternary geology, geological disasters, geologic structure, hydrographic features, etc, thus building diagrams, such as regional remote sensing interpretation geomorphologic map, Quaternary geological map, hydrogeologic map, tectonic map, etc. This paper takes application of remote sensing in hydrogeological general survey(revision) of 1:200 000 mountain region in Hebei Province as an example, to systematically introduce technical route and technical method of remote sensing applied in regional hydrogeological survey as well as main content of interpretation. The paper also combines the latest remote sensing technological development to look far ahead into application of remote sensing in regional hydrogeological survey and introduces a new direction.
