摘　　要：以西昆仑塔什库尔干地区为研究区,以WorldView-2高空间分辨率数据为主要信息源,在标准影像图制作基础上,针对性地进行图像增强处理,突出相关控矿要素和矿化信息,开展地质矿产遥感解译;利用ASTER和WorldView-2数据开展矿化蚀变有关的遥感异常信息提取,配合适量的野外调查验证,最终圈定了11处遥感找矿靶区。其中,A级遥感找矿靶区5处,B级遥感找矿靶区3处,C级遥感找矿靶区3处,其为后续区域地质矿产调查项目规划部署和矿产资源勘查评价提供依据;高分遥感技术在西昆仑地区矿产地质综合调查中作用显著,可实现找矿工作的快速突破,值得在相同或类似区域进一步推广应用。In this paper,the Taxkorgan area of West kunlun Mountains has been selected as a study object,the WorldView-2remote sensing images have been used as major data source to make standard image map and as the adopting methods to enhance the image for protruding the information of ore-controlling factors and mineralization,and the interpretation of remote sensing for mineral resources has been carried out.After using ASTER and WorldView-2data to carry out alteration anomaly information extraction,11 remote sensing prospecting targets have beencircled on through implementing a right amount of field investigation verification,including 5of A-class,3of B-class and 3of C-class,which are used as the basis for deploying mineral resources survey project and exploration and evaluation of mineral resources.Therefore,the high precision remote sensing technology is worth to be further promoted and applied in the same or similar area of West Kunlun,because it can realize the rapid breakthrough of ore prospecting work in the mineral geological survey.
