遥感技术在新疆双河市南部地热资源调查中的应用研究

Application of Remote Sensing Technology in the Investigation of Geothermal Resources in Southern Shuanghe City of Xinjiang

新疆地域辽阔,约占我国陆地总面积的六分之一,地热资源丰富,亟须开展地热资源勘查。采用最新的GF-2、Landsat-8卫星数据,对双河市南部地区进行1∶5万水文地质遥感解译,着重解译区内地貌、地质构造、泉点及泄出带的分布情况,采用landsat-8卫星数据进行地表温度反演,圈定地热异常点。结合野外验证,对各种地质和地热信息进行动态对比分析,论述了工作区内地热地质演化及趋势变化与地热地质要素的空间分布特性及相互联系,圈地了有效的地热靶区,为该区后期地热勘查提供依据,为新疆开展地热勘查寻找有效的技术方法提供了借鉴。

Xinjiang has a vast territory,accounting for about one-sixth of China’s total land area.It is rich in geothermal resources and urgently needs to carry out geothermal resources exploration.In this paper,the latest GF-2 and Landsat-8 satellite data were used to interpret the 1∶50000 hydrogeological remote sensing in the southern area of Shuanghe City,focusing on the interpretation of the distribution of landforms,geological structures,springs and discharge zones in the area.The Landsat-8 satellite data was used to invert the surface temperature and delineate the geothermal anomaly points.Combined with field verification,the dynamic comparative analysis of various geological and geothermal information was carried out,and the geothermal geological evolution and trend changes in the working area are discussed.The spatial distribution characteristics and interrelations of geothermal geological elements had delineated effective geothermal target areas and provided a basis for later geothermal exploration in the area.It provides a reference for Xinjiang to carry out geothermal exploration to find effective technical methods.
