摘　　要：随着空间技术和信息技术的飞速发展,遥感技术现已成为区域地质矿产调查评价的重要支撑技术,尤其是高分辨率遥感技术开启了微观遥感地质应用的大门。文章利用World View-2高分辨率遥感数据的技术优势,在西藏改则县北部地区开展矿产资源遥感调查研究,在遥感图像处理、地质解译及野外查证等工作的基础上,重新确定了该地区的地层岩性、岩体、断裂构造及其界线,新发现了9处金属矿化点,取得了良好的应用效果,充分体现了高分辨率遥感数据在海拔较高、地质工作程度较低地区的矿产资源调查中的技术优势及重要作用。With the rapid development of space technology and information technology, remote sensing technology has become an important supporting technology for regional geological and mineral resources survey evaluation, especially high resolution remote sensing technology opens up the gate of microcosmic remote sensing geological application. The paper carries out mineral resources investigation and research in the northern region of Gaize county, Tibet using the technical advantage of WorldView - 2 high resolution remote sensing data. Based on remote sensing image processing, geological interpretation and field verification work, etc. , the stratum lithology, rock body, fault structure and their boundaries have been re - outlined, and nine mineralization occurrences were discovered. Therefore it has proved that the technical advantages and important role of WorldView - 2 high resolution remote sensing data for mineral resources survey in those areas with high altitude and poor exploration work.
