基于多源遥感数据的云南西双版纳地区地质构造解译

西双版纳地区地处云南横断山系纵谷南段西双版纳热带雨林区，常年高温多雨、植被茂密、地形复杂，出露地质信息少，给区域地质调查工作造成了很大的困难。为有效获取该地区更多的地质信息，配合使用Landsat 8 OLI、SPOT 6、Sentinel-1A雷达遥感数据和高程数据等多源数据，基于建立的解译标志，提取区内地质构造信息，大至宏观上的大地构造背景信息、小至露头尺度构造信息，并详细分析区内各类型线性断裂构造的遥感影像特征与地质意义。提取的构造结果表明，原地质构造与解译构造吻合度较高，同时新解译出大量的线性构造。研究成果为完善该地区的地质构造轮廓与特征认识提供了丰富的遥感基础资料。

Interpretation of geological structures in Xishuangbanna, Yunnan based on multi-source remote sensing data

Located in the Xishuangbanna tropical rainforest area in the southern longitudinal valley of the Hengduan Mountains in Yunnan, Xishuangbanna area is featured with high temperature, heavy rain, dense vegetation, complex terrain and less geological information, which has caused great difficulties for regional geological survey. In order to effectively obtain more geological information, this paper consults the established interpretation marks and multi-source data including Landsat 8 OLI, SPOT 6, Sentinel-1A radar remote sensing data, elevation data, etc., trying to extract the geological structure information in the study area from the macroscopic tectonic environment information to microscopic structure information of outcrop scale, and analyze in detail the remote sensing image features and geological significance of linear fault structures of various types in the region. The extracted structure results show that the original geological structure and the interpreted structure are highly consistent, and a large number of linear structures are newly interpreted. The research results provide a wealth of remote sensing basic data to improve the understanding of the geological structure contours and characteristics of the area.
