摘要: 传统的地热勘察方法周期长且资金投入大,秭归县地处鄂西山区,复杂地形加剧了地热勘察成本。本文采用机载热红外遥感技术开展研究。首先,以秭归县五龙温泉为核心,圈定了1.05 km2的矩形区域,采用搭载热红外镜头的DJI Mavic 3无人机进行冬季昼、夜航测,成功识别出5个典型地热异常区;然后,通过判读和筛查,锁定2个地热资源靶区;最后,对2个靶区进行实地勘踏和补充调查,发现其中一个靶区与五龙温泉自然出露点吻合,另一个为新发现的地热露头。研究结果表明,机载热红外遥感技术在地热勘察中具备可靠性与应用性,能有效缩短勘察周期、降低成本。

Abstract: Traditional geothermal exploration methods feature long-term cycles and high costs.In Zigui county,located in the mountainous area of western Hubei province,complex topography further inflates exploration expenses.This study applies airborne thermal infrared remote sensing (TIRS)technology to overcome these challenges.A 1.05 km2 rectangular area centered on Wulong hot spring in Zigui county is selected.A DJI Mavic 3 unmanned aerial vehicle(UAV)equipped with a thermal infrared camera conducted winter daytime and nighttime aerial surveys,identifying five geothermal anomaly zones.After interpretation and screening,two geothermal target areas are determined.Field investigations show that one area matched the Wulong hot spring outcrop,while the other is a newly discovered geothermal site.The results prove that TIRS technology is reliable and applicable in geothermal exploration,effectively shortening the exploration cycle and reducing costs.

Key words: TIRS, infrared remote sensing, UAV, thermal anomaly, mountainous area of western Hubei
