遥感技术在汉中天坑群地质遗迹调查中的应用

随着遥感技术的不断发展,遥感新理论、新方法广泛应用于地质遗迹资源调查。本文结合《汉中天坑群地质遗迹调查》项目,通过采用不同空间尺度的影像数据进行遥感解译,全方位展示了工作区内岩溶地质遗迹的分布特征及外部形态,在汉中南部发现了88处重要的岩溶地质遗迹资源。结果表明:遥感技术方法的应用创新了汉中岩溶区地质遗迹资源调查的技术方法,提高了调查精度,为分析汉中南部天坑形成机理提供了理论依据,也为开展类似地质遗迹调查工作奠定了基础。

Application of remote sensing technology in geological relics investigation of Tiankeng Group in Hanzhong,Shaanxi

With the continuous development of remote sensing technology, new theories and methods of remote sensing have been widely used in the investigation of geological relics resources. Based on the project of Hanzhong Tiankeng Group Geological Relics Survey, this paper presents the distribution characteristics and external morphology of karst geological relics in the working area through remote sensing interpretation of image data with different spatial scales. Through multi-level remote sensing interpretation of the work area, a large number of karst geological relics resources have been found in the south-central part of Han Dynasty. The results show that the application of remote sensing technology and method has innovated the technical method of geological relics resources investigation in Hanzhong karst area, improved the accuracy of investigation, and laid a solid foundation for similar geological relics investigation work.
