摘　　要：资源一号02D(ZY1-02D)卫星为我国首颗高光谱业务卫星,为了测试ZY1-02D高光谱载荷数据在地质矿产调查中的应用能力,在数据预处理的基础上开展岩性及矿物信息识别,并与GF-5数据提取结果进行对比分析,结合实地调查成果,对该数据的应用能力进行了有效的分析。结果表明:ZY1-02D高光谱数据反射率光谱曲线与地质体光谱曲线形态吻合度高;经过岩矿信息识别,结合研究区地质矿产资料,显示提取的大理岩、二长花岗岩等岩性信息,方解石、白云石等造岩矿物信息以及绿泥石、褐铁矿等蚀变矿物信息与实测成果较为吻合,表明该数据对岩矿信息的识别效果较好,可为高光谱技术在地质矿产领域的业务化应用提供数据保障。The ZY1-02D satellite is the first hyperspectral operational satellite in China.To test the application ability of ZY1-02D hyperspectral loading data in geological and mineral survey,the authors identified lithologic and mineral information on the basis of data pre-processing,and the results were compared with GF-5 data.The application ability of the data was analyzed effectively in combination with the results of field survey.The results are as follows:the coincidence degree of ZY1-02D hyperspectral data reflectivity spectrum curve and geological body spectrum curve is high in shape,which can meet the requirements of rock and mineral information identification;through the identification of rock and mineral information in combination with the geological and mineral data of the study area,it is shown that the lithological information of marble,monzogranite,calcite and dolomite and alteration mineral information of chlorite and limonite are consistent with the measured results.The results show that the data has good recognition effect on the information of rocks and minerals,and can provide data guarantee for the application of hyperspectral technology in the field of geology and mineral exploration.
