摘　　要：为了对境外地质矿产勘查开发提供遥感信息支持,在综合前人研究成果及野外验证基础上,对塔吉克斯坦帕米尔地区的地质和构造特征进行深入分析和研究;根据不同地质体的特征影像,对照"资源一号"(ZY-1)02C星遥感图像中所显示的地貌景观、色调及纹形等,建立了塔吉克斯坦南部地区主要沉积岩、变质岩和侵入岩以及断裂构造、褶皱构造和环形构造等的遥感解译标志;通过对ZY-1 02C星的全色/多光谱相机(P/MS)和全色高分辨率相机(HR)数据的遥感地质解译效果对比,认为P/MS数据中地质体的色调差异更为明显,易于建立区域构造格架、开展岩石大类解译;而HR数据所反映地质体的微地貌、纹理及细节更为清晰,易于进一步识别各类岩性及小型构造,尤其对碎屑岩的粒度、层状构造类型、第四系、矿业活动以及特殊成分的岩石等具有较好的反映。In order to offer remote sensing information support to geological and mineral resources survey and exploration overseas, the authors conducted further study of geological phenomena and structural characteristics in target areas of Tajikistan on the basis of previous results and current field exploration, established interpretation marks for sedimentary rocks, metamorphic rocks, intrusive rocks, fault structure, fold structure and ring structure in southern Tajikistan area with reference to ring geomorphologic landscape, tune, and stripes shown on remote sensing images gathered by ZY - 1 02C satellite. A comparative analysis of panchromatic muhispectral camera （P/MS） data and panchromatic high- resolution camera（HR） data received by ZY -1 02C satellite demonstrates that the color of geological bodies in P/MS has stark contrast so that it is more convenient to establish regional tectonic structure and carry out interpretation on rock categories, whereas micro -topography, grains and details of geological bodies shown in HR are clearer, which is suitable for identifying lithologieal charateistics and minor structures, especially for types of stratified structure, granularity of clastic rocks, Quaternary, mining activities and rocks with unique components.
