摘　　要："高分二号"(GF-2)卫星是迄今为止中国研制的空间分辨率最高的民用遥感卫星,标志着中国民用遥感卫星进入亚米级"高分时代"。为了更好地了解卫星的应用性能,充分发挥和利用好GF-2卫星数据在地质矿产调查工作中的应用,尤其是在条件艰苦地区和境外区域。文章利用GF-2卫星在新疆哈密地区的相关影像数据开展了遥感地质调查应用评价,从数据处理、地质构造信息提取、地层及岩体等岩性信息的识别,以及可识别地质体精度等方面分别进行评价。结果表明,GF-2卫星数据能有效地划分遥感影像地质单元、识别地质构造空间展布特征,很好地满足优于1∶25 000尺度的遥感地质调查工作,可为地质矿产资源调查及评价提供强有力的数据支撑。The GF-2 satellite is civilian remote sensing satellite of the highest spatial resolution in China, marking that our country civil remote sensing satellites enter into the submeter level. In order to understand the application performance of the satellite, and make full use of the GF-2 satellite to geological survey, especially in the difficult conditions area and overseas area. In this paper, we use GF-2 satellite data of the Xinjiang Hami area to carry out the evaluation of application in remote sensing geological investigation. We evaluates the GF-2 data in term of data processing, extraction of geological structure information, stratum and rock information, and precision of identifiable geological body. The results show that GF-2 satellite could effectively divide the remote sensing image geological unit, identify the geological tectonic characteristics of spatial distribution.It can suffice the needs of the remote sensing geological application with better than 1：25 000 scale, and can provide powerful data support for geological investigation and evaluation.
